https://killexams.com/exam_list/HPKillexams : Top 5 printer problems and how to fix them
It’s frustrating when the tech we rely on doesn’t work as it should, and printers are no exception. In our latest annual tech experience survey, we quizzed over 16,000 people* to uncover the most common printer problems.
Many of the issues we heard about were related to poor print quality, which meant users were struggling with colour imbalance and smudged text. Other respondents told us that the paper wasn't feeding into their printer correctly.
On the plus side, our study found that many people were able to fix these problems themselves, so you don't necessarily need to pay a professional.
Keep scrolling for details on how to ensure your printer is working at its best. If you're thinking of replacing your current printer entirely, we've also rounded up some tips on picking the perfect alternative.
Deterioration in print quality was by far the most common problem experienced by respondents. Users told us they had noticed colour imbalance and white lines on prints. Text was flawed, too, landing in the paper tray looking spiky, misaligned or smudged.
To fix, simply turn your printer off and on again to see if there's an instant solution. If not, check whether your ink cartridges need replacing.
To check printer ink levels on Windows, follow these steps:
Click the Start button in the bottom-left corner of your screen.
Search for Printers & Scanners.
Click on the printer you want to check and select Manage.
If your printer is low on ink, you'll see a message next to Printer Status that says so.
To check printer ink levels on Mac, follow these steps:
Click on the Appleicon and go to System Preferences.
Select Printers & Scanners and choose your printer.
Click Options & Supplies.
Ink levels are shown under the Supply Levels tab.
If your cartridges have plenty of ink left, poor print quality might be caused by blocked printer head nozzles – those are the components that spray ink onto the paper. This is more likely to happen if you don’t use your printer very often, as dried ink can cause a blockage.
Cleaning the nozzles could help. You can do this by running your printer’s cleaning function, either via the brand's printing app on your computer or on the printer itself. Consult your printer’s manual if you’re not sure where to find it.
If the self-cleaning function doesn't solve your problem, you can clean the printer head manually. Use a lint-free cloth dampened with warm distilled, filtered or bottled water.
To tackle text that doesn't line up correctly, have your printer perform an alignment – you'll see an option for this in your printer settings. Turning it off and on again after 30 seconds can also fix the problem.
Your printer paper could also be causing smudging or feathering, so confirm that you're using the right printer paper for the job. Damp, curled or wrinkled paper can affect print quality.
General hardware problems were also widely reported in our survey. These could be more difficult to fix yourself if components need replacing. If you suspect a hardware issue – maybe the printer won’t print or won’t turn on – check the basics first.
Ask yourself the following:
Have the cables become disconnected or are they damaged?
Is there a paper jam?
Has the paper been loaded incorrectly?
Is the power light on?
Are there any flashing lights that could indicate a problem?
Once you’ve checked all of the above and, assuming you’re able to print, try to print a self-test report – this could tell you what’s causing the problem.
To run a test report on Windows, follow these steps:
Click Start, then Settings > Devices > Printers & Scanners.
Select your printer and choose Manage.
Click Print a Test Page.
To run a test report on Mac, follow these steps:
Click on the Apple icon and go to System Preferences.
Select Printers & Scanners and choose your printer.
Click Open Print Queue > Printer > Printer Test Page.
If you need to pay for a printer repair but don't fancy spending big, there's good news. According to our survey, the average repair cost for an inkjet printer is lower compared to any other type of tech product we asked about: £42 compared to £74 for wireless headphones and £73 for laptops.
3. Problems with paper
This can be caused by dusty or dirty rollers, obstructions in the paper tray, an overfilled paper tray or even the paper itself. If turning the printer off and on again doesn’t fix it, check the paper you're using.
Your printer paper should all be of the same size and type, and loaded properly, with the edges of each sheet aligned. Issues with the paper can cause paper jams, too. Remove the paper and, using a torch if you need to, check for obstructions in the mechanism inside the tray.
Try cleaning the rollers inside the paper tray using your printer’s roller-cleaning function, if it has one. Alternatively, use a long cotton swab dampened with distilled, bottled or filtered water, but make sure you unplug the printer first.
Rotate the rollers as you clean them, and leave them to dry for 15 minutes before turning your printer on again.
Our printer survey also uncovered problems linked to ink jets or nozzles on the print head not working, which can happen if your printer hasn’t been used in a while.
Try cleaning the print head. As we mentioned earlier, you'll need to use a damp lint-free cloth. If the print head is built into the ink cartridges, replacing it could fix the problem – consult the user manual or the brand's website for more details. The HP website, for example, has a walkthrough on replacing a print head.
Some printers feature print heads that can't be removed, so you'd need to get the part replaced professionally.
In some cases, it's more economical to buy a new printer than to pay for a new printer head. If you're leaning towards buying a new printer, consult our printer reviews to secure a Which? Eco Buy model combining quality printing, energy efficiency and low running costs.
5. Wi-fi connection problems
A printer that connects to your home wi-fi network lets you queue jobs from a phone or computer without a cable. However, some respondents told us they were struggling with this.
If you’re unable to print over wi-fi, check that your printer’s software is up to date by visiting the manufacturer’s website. Most brand sites will make this an easy task, especially if you have your model number to hand.
We’ve included the most common manufacturer site links here:
Investing in a wi-fi extender can help Improve your internet coverage – these plug into the wall and boost the signal coming from your router. Some models will create an extra network that appears in the list of available networks on your devices. Often, the extender will mirror the name of your normal network with 'EXT' at the end.
Other wi-fi extenders work within a mesh system, boosting your existing router network without creating an extra one. These allow you to stay on the same network right through your home, but they tend to cost more.
If your current printer leaves you feeling frustrated, it might be time to look for an alternative model. At Which?, we rigorously test the latest printers to help you pick the perfect one for you.
When buying a new printer, you'll need to decide whether you want to purchase an inkjet or laser model. Inkjets are typically cheaper up front and cost more to run, while laser printers are pricier to buy but can produce quality prints faster and more cheaply. Tank printers (often inkjet models) are extremely cheap to run, but can be expensive to buy.
Size – if you're limited on space, you'll want a printer that performs brilliantly but doesn't take up too much room.
Ink and paper capacity – consider shopping for a printer with a large capacity for paper and ink so you don't need to constantly replace them.
Running costs – some of the best printers may seem expensive initially, but they cost less than cheaper models to run throughout the year.
Print quality – colour accuracy and sharpness are key, which is why our expert reviews cover print quality in detail.
Printing speed – using a printer that takes a lifetime to print can be particularly frustrating. For every printer we test, we time the print speed of different types of documents and how long it takes to turn out the first page.
If you're thinking of buying a new printer, explore our guide to the best printers – our expert reviews are backed by rigorous lab tests.
Recycling your old printer
If you're looking to replace your printer, you can't just throw it in your rubbish bin.
The good news is that recycling your printer is fairly simple – a number of high street stores are willing to take your unwanted printer if you buy a replacement from them. Note that Robert Dyas, Argos and Currys accept second-hand printers.
Some local councils are unable to collect small electricals directly from your home. If council collection isn't an option, you can visit a recycling centre – there are thousands across the UK. For an overview of nearby donation points, enter your postcode on the Recycle your Electricals website.

Every student is different, so the best student laptop for one user might not meet the educational expectations of the next. That’s why it’s so important to appreciate the pros and cons of one model in comparison to another. And that’s why we have taken the time to compare two of the most top-rated student laptops on the market today.
Luckily, most students are once more studying in college and university rather than at home, but the need for a good student laptop remains just as high. Indeed, with so much on-the-go work needed, having a system that can go the distance is more important than ever.
So, if you’re interested in investing in the HP Pavilion 14 or the Acer Chromebook 315, then read on to discover how each machine stacks up in all the areas that count, including performance, display real estate, battery life, components and more.
HP PAVILION 14 VS ACER CHROMEBOOK 315: DESIGN AND USABILITY
The Pavilion series has always produced easy on the eye laptops, and the Pavilion 14 continues that trend with its sleek, silver-white aluminium chassis. It’s a relatively lightweight model at only 1.54kg, and with dimensions of 12.8 x 8.5 x 0.7 it’s comfortably thin as well (making it ideal for commutes).

It may come as a surprise, but music is a tried-and-true therapy for healing in the eyes of science. Numerous studies support its benefits in combination with other treatments, as well as on its own. Still, we don’t know much about its mechanism—we know that sound can provide physiological benefits, but not how.
A new study in mice, published Thursday in the journal Science, reveals a recipe for leveraging music as a potential pain reliever and providing a low-cost, widely accessible alternative to traditional pharmaceuticals.
A team of neuroscientists from China and the U.S. injected the hind paws of lab mice with complete Freund's adjuvant, a solution that causes inflammation and pain. Then they prodded the hind paws and observed the threshold at which the mice flinched—providing a measurement of each animal’s tolerance for pain.
The team went on to play sounds at levels slightly higher than background noise and observed what kinds of effects these sounds had on the mice’s pain tolerance. It seems like the mice weren’t music snobs: They reacted equally to classical music, dissonant music, and white noise when each was played 5 decibels louder than ambient noise.
Whatever the music was, the overall effect was remarkable: The sounds being played led to significantly lower pain levels for the mice, a result that persisted even two days later.
“In the future, these findings could spur the development of alternative interventions for treating pain,” the authors wrote in the new paper.
Once they had evidence that the music therapy worked, the researchers peered into the mice’s brains and recorded the regions that lit up when they played the soothing sounds. They traced the effects through regions called the neocortex, thalamus, and brainstem to show how the music competed for airtime in the brain with pain signals from the paw.
According to an accompanying perspective article in Science written by Heidelberg University biologists Rohini Kuner and Thomas Kuner, previous explanations for the pain-relieving properties of music focused on sounds’ ability to distract listeners. While sound “likely contributes to distraction,” they wrote that the study details a new and distinct pathway for pain suppression.
They also speculated that the secret sauce that explains the 5-decibel effect was its ability to trigger defensive instincts in the mice. If so, a fight-or-flight response would have lowered their perceptions of pain as the mice focused on more pressing concerns, like avoiding a potential threat. “From an evolutionary perspective, it makes sense that sound-driven defense behaviors are acutely accompanied by pain suppression,” the Kuners wrote.
Even so, we need to study this phenomenon in more depth before we can start firing off pain-relieving noises to patients in need.
“Using rodents to study how music and sound are related to pain presents major challenges, not least because it is unknown how animals perceive music,” the Kuners wrote.
On this point, the Chinese and American team seems to agree. “The neural mechanisms underlying music-induced analgesia in humans are doubtlessly more complicated than those revealed in mice,” they wrote.

Dr. Ali Tinazli is the CEO oflifespin.healthand has 15+ years in Fortune 100 corporate strategy and entrepreneurship (SONY, HP).
Society has benefited from remarkable scientific advances in the 21st century; perhaps few are more profound than the extraordinary achievements in human health, thanks to the convergence of biology, medical science and information technology. It is now possible, for instance, to sequence an individual's entire genome rapidly and inexpensively.
At the same time, developments in wireless technologies and big data make it easier to collect and store large amounts of health-related information. The convergence of these two trends and others is revolutionizing the diagnosis and treatment of disease and ushering in a new era of deeply precise, individualized medicine that may forever alter healthcare delivery to millions of people.
One of these significant advances is in using bioinformatics, specifically the identification and utilization of human "biomarkers" to accelerate the development of improved and innovative diagnostics. An offshoot of this field is called "metabolomics," a relatively new branch of medical science that holds great promise in making precision medicine affordable and more accessible.
Metabolomics, from a health standpoint, is the study of how disease impacts a person's normal metabolism, representing the biochemical process involved in virtually everything human beings do—from moving and growing to thinking. Diseases are believed to cause a disturbance of healthy metabolism, which leaves biochemical patterns in the human body, e.g., in blood.
Physician-scientists have long believed and found, through research, that these changes in a person's biomarkers, i.e., their metabolism, can provide valuable and early indicators for disease states and other health-related conditions. For example, if two patients come to their physician with identical symptoms, a blood test would differentiate their illnesses and accurately diagnose them. But only until relatively recently, because of advances in the convergence of various technologies, has this promise become a reality.
Today, these metabolic signatures are not only traceable but are also beginning to be very accurately correlated to specific disease states, utilizing powerful digital platforms that use deep learning, advanced software solutions and artificial intelligence, all cost-efficiently scalable via the cloud. Powered by metabolomics as a new and near-universal health diagnostics modality, early and rapid identification and treatment of diseases—as well as general wellness information—may, for the first time, become far more accessible and cost-effective, not just for those living in industrialized nations with well-developed health care systems, but for the global population as well.
Here is a brief explanation of how technology will contribute to the innovative digitization of diagnostics.
Deep learning algorithms map out disease progression based on quantitatively "scanned" patient samples.
Deep learning algorithms have the potential to Improve diagnostic accuracy by providing a more comprehensive analysis of a patient's medical history, lab results and symptoms. Doctors can then use a more accurate picture of their condition to identify any early warning signs of illness.
In addition, deep learning algorithms can enable healthcare providers to monitor a patient's condition over time, making it possible to detect changes that might indicate the need for further testing or treatment. As a result, deep learning algorithms have the potential to vastly Improve the accuracy of diagnosis and Improve outcomes in the treatment of complex illnesses.
At my company, our focus is on using proprietary deep learning algorithms to identify significant deviations in metabolic networks of different health conditions. These deviations are captured quantitatively by "scanning" blood samples for metabolites with a physical method called nuclear magnetic resonance (NMR). This interface between the classical diagnostics world with patient samples in a wet lab combined with information technology elevates the technology convergence in healthcare to the next level.
We use these algorithms to map out how diseases progress, which is crucial for diagnosing and developing more effective treatments. For example, our algorithms might identify that a particular illness progresses by causing a build-up of toxins in cells. We can then use this information to develop a treatment that targets the build-up of toxins rather than the disease itself.
AI elevates the analysis of metabolic data.
Understanding how different parts of the human body interact is essential for developing new diagnostics and effective treatments for various medical conditions. However, this information is often scattered across multiple databases, making it difficult to access and use—AI keeps all the data in one place.
AI is beneficial in clinical research because it can differentiate and diagnose chronic diseases through patterns in human metabolism. Doctors can now diagnose and treat chronic diseases more accurately by using AI to analyze these patterns. Analyzing metabolomic data, AI can help identify new drugs that could effectively treat diseases.
Cloud-based platforms are improving access to human health technologies.
Standard diagnostics are typically slow, cumbersome and tedious, making them costly and difficult to access. New technologies sought after for deeper clinical insights are associated with the same attributes, making it challenging to get accepted into the standard of care. These technologies at the interface of biology and IT typically require a lot of computational power but can now be handled cost-effectively in the cloud. A new diagnostics platform that can scale cost-efficiently as a cloud-based solution will lower the barriers to entry. It will be intrinsically more accessible to providers and patients.
Complex diseases are often challenging to diagnose and treat. Cloud-based digital platforms provide new opportunities for providers to offer precise diagnostics tools to their patients and facilitate tailored treatments for these conditions. These platforms can help identify patterns and trends useful in differential diagnosis by analyzing large amounts of data. Therefore, cloud-based digital platforms will be essential in supporting better treatments for chronic diseases.
The future of human health is now.
Human health has been monitored and managed for centuries using crude tools and methods. With the advent of technology, we can now digitize every aspect of our health for accelerated and improved healthcare services. Most importantly, these next-generation cloud-based tools for precision medicine will be more accessible and affordable, enabling adoption on a broad population level. Imagine the impact for millions worldwide as expedited diagnoses and disease prevention becomes an everyday reality.

When it comes to plastic pollution in bodies of water, turtles ensnared in six-pack rings merely skim the surface. Many don’t realize that invisible chemicals leach from microplastics and full-sized plastic refuse left baking in the sun, disrupting aquatic ecosystems from the bottom up.
A new study measured the impact of plastic bag chemicals on some of lakes’ smallest residents, finding that the leached chemicals boosted the growth of bacteria when compared to distilled lake water alone. To stem an overgrowth, bioremediation solutions could add even more bacteria to the affected ecosystems, the evolutionary biology researchers propose in a new study published Tuesday in Nature Communications.
Writ large, the research shows how badly we’re messing up the planet with our actions, senior author and University of Cambridge global change ecology researcher Andrew Tanentzap told The Daily Beast. “We’re potentially changing the whole food web,” he said.
To pinpoint the impact of the leached plastic chemicals, Tanentzap’s team first sourced plastic bags from the British shopping chains John Lewis, Superdrug, Clintons, and Next, and left small samples of the bags under an LED lamp while immersed in water for seven days. They filled Nalgene bottles with surface water from 29 different Scandinavian lakes and added the bacteria from each of the samples into distilled water and water with the leached plastic bag chemicals.
Lake bacteria grew on average more than twice as fast in the chemical water, even though the concentrations added were less than 10 percent what they would be in the lakes. Future work is needed to determine why the plastic bag chemicals caused such a drastic shift in growth, but Tanentzap theorized that the low concentration of chemicals might “prime” the bacteria for rapid metabolism.
“Let’s say you’ve got some celery, and celery is really nasty, full of long fibers and really hard to digest, but I dangle some maple syrup in front of you to get your appetite going,” Tanentzap said. Once you’ve exhausted the maple syrup, you might still be hungry—plus, you’ll have a bit of extra energy, perfect for digesting long fibers. “Now you’re going to break into that celery,” he said.
“I don’t want people to think that they can just drop their little pieces of plastic in the lake and that’s good for the microbial community.”
— Ludmilla Aristilde, Northwestern University
Bacterial overgrowth could do a number on a body of water’s ecosystem, but researchers don’t yet know the full consequences of these plastic bag chemicals as they accumulate in larger organisms that feed on bacteria and work their way up the food chain, Tanentzap said.
But, counterintuitively, the bacterial growth might be a positive sign, too, since it signifies that the plastic chemicals are being broken down and potentially degraded. The researchers determined the level of species diversity present in their lake samples, finding that more diverse communities were given bigger boosts in growth by the chemicals. Given enough time—and potentially aided by bacteria known to break down plastic—these bacterial communities could metabolize enough of the chemicals to stop their own growth from ballooning out of control. Environments that lack in bacterial diversity, on the flip side, may benefit the most from human-led cleanup efforts, Tanentzap said.
Ludmilla Aristilde, a Northwestern University civil and environmental engineering researcher who was not involved in the work, called it “surprising” but drew attention to a number of its limitations. By only focusing on bacterial growth, the researchers may have missed a telltale warning sign of poor environmental health: The presence of harmful algal blooms.
“I don’t know how much they have algal bloom problems in Scandinavian lakes, but we know in the Great Lakes and other lakes that it’s a problem that can affect the rest of the drinking water system,” she told The Daily Beast.
There are three main types of plastic, Aristilde said; the focus on just one type suggests that the effects of plastic chemicals may be even more pronounced. And future studies may want to look at the impact of these chemicals in more biodiverse bodies of water.
While the impact of plastic chemicals might be unanticipated or even positive for certain species of bacteria, it’s important for the public to realize that there is no upside to pollution, Aristilde said.
“I go swimming in Chicago’s lake all the time,” she said. “I don’t want people to think that they can just drop their little pieces of plastic in the lake and that’s good for the microbial community.”

Culture And Behaviours
Ahead of EHS Congress, taking place in Berlin in September, SHP catches up with speaker Jenna Merandi, Medication Safety Officer at Nationwide Children’s Hospital, to discuss proactive safety and how proactive safety observations can be incorporated within a business.
Tell me a little about your background, how you got into safety and the role you are in today.
Jenna Merandi (JM): “I obtained my Doctor of Pharmacy degree at West Virginia University College of Pharmacy. Following completion of my PharmD, I began a two-year administrative and clinical residency training program at Nationwide Children’s Hospital in Columbus, OH while obtaining my master’s degree at The Ohio State University in Health-System Pharmacy Administration.
“During my residency training, I was directly involved in a medication error. Following this event, it allowed me to see first-hand, the robust system review, supportive culture, and the actions taken to prevent this type of event from recurring. It was in those days and weeks ahead, I realised, that I wanted to focus my career on safety.
“After my residency training was complete, I was hired by Nationwide Children’s Hospital as a medication safety pharmacist and now serve as the Medication Safety Officer (MSO). In my current role, I work closely with interdisciplinary teams and frontline staff to learn from everyday work and identify system-based interventions to prevent errors in healthcare. As Medication Safety Officer, I serve as a co-leader on hospital-wide Adverse Drug Event Quality Collaborative and work with teams to operationalise proactive safety concepts and tools while enhancing learning opportunities to help keep our paediatric patients safe.
“I provide strategy, innovation, and expanded views about safety (Safety Differently) to help lead our journey to best medication outcomes.
“Through my work as MSO, I have served in various national leadership roles including founder and chair of the Children’s Hospital Association Medication Safety Leaders Collaborative, co-leader of the Solutions for Patient Safety (SPS) Safety II Think Tank and have provided numerous presentations and webinars around operationalising Safety II/proactive safety concepts in healthcare, development of second victim peer support programs, as well as other various topics.
“When people ask me what I do in my role? I simply state, “I help keep kids safe” and there is nothing more rewarding than doing this each and every day.”
You are a believer in of the Safety II approach, but prefer the term, ‘proactive safety’. Why is that and how has that resonated with staff in the healthcare sector?
(JM): “I am a believer in the Safety II approach, and a believer in various other theories in safety. I prefer to utilise the term ‘proactive safety’ as it is more recognisable, understandable and actionable by frontline healthcare staff. Additionally, it can encompass variety of theories vs. just singling out safety II only.
“Traditional safety efforts (safety I approach) are still widely utilised and valued in healthcare. Therefore, when expanding the lens to also focus efforts to analyse complexity and adaptability of a system that results in success (safety II approach), there is a tendency to label safety I vs. safety II. By doing this, it may lead to staff indirectly assigning value distinctions (safety II is better than safety I) instead of seeing both approaches as complementary.
“In healthcare, we have often spent less time focusing on the presence of capacities that enhance successful outcomes (for example, psychological safety amongst team members, team dynamics, resource availability, etc.) as more time is spent focusing on the more conventional study of failures (how and why things went wrong). However, there is a lot of opportunity to analyse complex systems and why they succeed (as this happens majority of the time).
“Though traditional safety concepts are valuable and still utilised, there is opportunity to incorporate modern safety theories such as resilience engineering, Safety II, Safety Differently and Human and Organisational Performance.
“My goal as an MSO is to evolve the way safety professionals are practicing to Improve medication related outcomes.”
How have you incorporatedproactive safety observations and what have you learned from those observations?
(JM):“We have started utilising proactive safety observations and Learning Teams to better learn from everyday work. This has allowed us to identify areas of both risk and excellence.
“Through these observations we have identified system weaknesses such as technology failures that might lead to work arounds related to barcode scanning, ways to enhance set up in our automated dispensing cabinets to better error proof during removal of high-risk medications, and various other interventions.
“Other learnings observed have included why certain high performing teams continue to have successful outcomes. Asking questions using an appreciative inquiry approach has been a way to redesign the way we ask questions. For example, asking staff ‘think about a complex process that went well, what were the good catches, and what was it about the team, their behaviours, or system that helped contribute to a successful outcome?’ Through these conversations and observations, it brings greater understanding of how people adapt to overcome challenges and how can we ensure this happens again that way in the future.”
What are you top three tips for how tooperationalise safety II theory into practice?
Utilise proactive safety huddles – to anticipate and plan for potential risks when performing safety critical tasks. Proactive safety huddles can be utilised to enhance communication and raise concerns from a team in complex and unique situations.
Widen the lens of focus to expand learning opportunities – incorporation of learning teams and learning from successful every day work is just as important as learning from undesirable events and outcomes. Learning from those that do the work, evaluating environmental factors, and utilising simulation to identify latent safety threats can all help contribute to making a system safer.
Try not to introduce SII as something ‘new’ and avoid focusing on the terminology and language – Instead, talk about what it is, what it adds, and how it broadens the lens to what safety is and can be. Safety II harnesses the expertise of people on the frontlines doing the work. We can learn from their excellence as well as the risks they identify.
Finally, you will be speaking at EHS Congress in Berlin in September, what can delegates expect from your session?
(JM): “You can expect to hear innovative ways modern safety concepts are being operationalised in healthcare. This session will draw upon various modern safety theories and real-life application in a high-risk area such as medication safety in one of the largest paediatric hospitals in the United States. Delegates can also expect to hear ways this has been successful and challenges and barriers that exist.”

The Texas-based motorsport company, which has made a name for itself with its Grunt and Runt electric motorcycles, has just just unveiled its first UTV, the Stag. The brand’s first four-wheeler has an 80 mph top speed and looks like a natural addition to its lineup of ultra-capable off-roaders.
More from Robb Report
The Stag may be Volcon’s first UTV, but it looks like the brand already knows what it’s doing. It’s powered by a single electric motor that can generate up to 125 hp and 265 ft lbs of instantaneous torque. If that somehow isn’t enough for you, an optional power boost package pushes output past 140 horses. Thanks to all this grunt, the Stag can hit a top speed of 80 mph and tow up to 2,000 pounds. The powertrain gets its juice from a 42-kWh battery pack that will allow it to go 100 miles between charges. That should be more than enough for a day of play off the beaten path. The entire rig can be recharged in seven hours thanks to integrated Level 2 charger.
The UTV should also be a breeze to handle thanks to its low center of gravity and a suspension equipped with fully adjustable shocks. It also comes with high-performance BF Goodrich Mud-Terrain T/A KM# tires, so not even muddy conditions will slow you down. There also an on-demand four-wheel-drive for whenever the road in front of you looks particularly treacherous.
The Stag features a heavily sculpted and athletic body, a caged passenger cabin and a 13.4 cubic foot cargo bed for all your gear. Inside the cabin, you’ll find a driver’s cockpit equipped with a tilting steering wheels and two digital displays so you can monitor vehicle status and track where you’re going using GPS. You can also use the setup to control the vehicle’s two integrated cameras, which will allow you to capture all the fun you’re having. The vehicle is equipped with ergonomic premium seats in the front and back and can comfortably fit four adults.
