Why Is My Printer Not Working? Top Causes of Your Large Format Printer Issues

Don’t let printer problems slow your business down. If you keep asking yourself, “Why is my printer not working?” then find the answer to common problems in our simple guide.

Large format printers are among the most effective machines for printing high-quality, large-scale graphics like banners and printers. They're also useful for printing many high-resolution documents, including blueprints, architectural plans, and maps. However, like most technology, large format printers can experience failure and breakdowns if issues prevent them from operating properly. These issues range from software problems to hardware errors. As a result, you might be asking, "Why is my printer not working?"


If your large format printer isn't working as it should, it can be frustrating and result in lost productivity. Thankfully, it's relatively easy to solve most large format printer issues with the right troubleshooting solutions or other effective fixes.


Whether you're a professional large format user or a hobbyist, learning more about the various solutions to common printer problems will help you keep your printer fully functional.

What Are the Most Common Causes of Large Format Printer Issues?

If you're experiencing printer trouble, it could be due to the following common causes. So, if your main question is, "Why is my printer not working," consider these issues:

The Printer Connectivity or Software Is Defective

In some cases, the main issue may come down to issues with your network connectivity or software. As a result, your printer may be unable to connect to computers because of a broken connection or incompatible or incorrectly installed software, such as printer drivers.

The Solution

Check to see if your printer is connected to the network. If it isn't, see if you can connect it manually again, and check to see if your entire network is up and working. You may need a more reliable connection if your network is running but you cannot print. If connectivity isn't an issue, you might need to upgrade or change the software. Ensure all printer drivers are compatible with both your computers and printer, and keep your software up to date.

There Is a Banding Issue

This issue is among the most common, but it's also one of the easiest to solve. Banding involves vertical or horizontal lines appearing on the page when printing. It could be due to a number of specific issues. For example, banding may result from:


  • Incorrectly set heaters
  • Improperly drying ink
  • Incorrect patterns when deflections are present in printheads
  • Incorrect head settings

The Solution

Typically, you should be able to solve this issue on your own by making necessary adjustments to your printer. For instance, if the bands are narrow, it might be an issue with ink drying incorrectly.

Ink and Toners Are Too Old

Another cause of printer trouble could be old ink or toner cartridges. Old inks and toners can cause issues such as banding or otherwise inconsistent and low-quality prints.

The Solution

Generally, after 18 months, it's best to change out your inks and toners to keep the supply fresh for your printer.

There Is an Issue With the Actual Hardware

Sometimes when asking, "Why is my printer not working," the answer may be issues with the printer's hardware. Printer parts such as printheads can get dirty over time, and parts may experience wear to the point where they require replacements.

The Solution

Check the printer's internal components, including printheads. You may simply need to clean your printer to get it up and running again, or you may need to replace parts or even the entire printer.

There’s a Paper Jam or Some Other Paper Issue

Finally, if you're still asking, "Why is my printer not working," it could be due to paper jams or other problems with your paper.

The Solution

Ensure your paper is compatible with your printer and that nothing in your system keeps the paper from passing through. Using high-quality compatible print materials will typically help solve paper issues.

What to Do to Avoid Large Format Printer Issues

To avoid the entire issue of "why is my printer not working," here are some best practices for maintaining your printer, which should help maximise its longevity and efficiency:

Keep Your Printer Clean

To keep your printer in top shape, you must keep it consistently clean. If you notice any issues with blurry images or low-quality prints, the next step may involve cleaning it and removing dirt and debris. You can clean your systems using supplies such as anti-static brushes; use them to clean everything from print beds to tubes and fans.

Use the Right Paper and Ink

Each printer needs compatible paper and ink to run smoothly. Look for print materials that work best for your brand, and consider buying direct from the printer's manufacturer.

Conduct Regular Maintenance Checks

Regularly cleaning and checking for worn or broken parts will help keep your printer in working order. If you notice any wear or breakage, it may be time for a replacement part or an entirely new printer.

Replace Old Equipment With New

Like other equipment, large format printers and their components age and begin to deteriorate. This is particularly the case when these systems undergo heavy use. If your equipment is old and inefficient enough to hold you back, replace it as needed. You might want to avoid spending money on replacement parts and printers, but replacing them when necessary could save you even more money in the long run.

Avoid Overheating Your Printer

Overheating can cause damage to your printer. To prevent overheating, keep your printer in a cool and dry location. Keeping your printer out of the sun and in a climate-controlled area with low humidity will help ensure your printer lasts longer.
