Operating a highly sophisticated technology like wall printing takes hours of expert instruction and professional training. On top of that, it might shut down completely due to minor problems which can be difficult to pinpoint. After all, it’s a technology with hundreds of components!
Different factors like print head quality, ink quality, quality parts, or neglected maintenance can affect your wall printer leading to subpar results, at times completely shutting down your machine.
Whether you are a professional wall printer or a DIY enthusiast, understanding these common issues can help you avoid costly mistakes. In this article, we will discuss the 6 most common wall printer problems and provide tips on how to troubleshoot them.
What are The 6 Most Common Issues With Wall Printers?
1. The Wall Printer Can’t Print
Your brand-new printer is not printing no matter what you do. It can be nerve- wrecking trying to figure out the problem if you have less to no training. Plus, the manufacturer does not offer technical support.
There can be several reasons why your new wall printer may not be printing correctly or printing at all. Some of the most common causes are:
Improper setup: Wall printers require proper setup before they can start printing. If the printer is not set up correctly, it may not print at all. Double-check the setup process to ensure that all cables and connections are properly secured and the printer is calibrated.
Ink issues: If the printer is not printing, it could be due to issues with the ink. The ink cartridges may not be installed correctly, or the ink may be clogged. It is essential to make sure the ink cartridges are installed correctly and the ink system is primed properly.
Print head issues: Another possible reason why a new wall printer may not print is due to problems with the print head. A damaged or clogged print head can cause printing issues. Check the print head and clean it thoroughly, if necessary.
Software or firmware issues: If the printer has outdated software or firmware, it may not work correctly. Make sure the printer is updated with the latest software and firmware.
Defective hardware: It is possible that a new wall printer could have defective hardware that is preventing it from printing. In this case, the manufacturer should be contacted to resolve the issue.

2. Broken Needle of Print-head
During the printing process, a thin vertical line like a needle may appear on the picture. This is due to a broken needle in the print head.
When the ink is not jetting correctly due to a clog in several print-head nozzles, it causes a break in the color flow leaving small needle-like lines.
Solution
Perform one or more ink pumps and use test strips to identify a broken print head immediately. Replace the print-head needle to prevent damage to your printer. Cheap, low-quality needles can break unexpectedly so, it’s imperative to use genuine high-quality print head needles.
3. Incorrect Color or Color Crosstalk
Sometimes, when you finalize the design and begin printing, the color on the computer screen differs greatly from the color displayed on the wall. It is mostly because the computer uses RGB colors while the vertical wall printer prints the image in CMYK “4 inks.”
It’s quite normal for the color to differ between the screen and the wall to some extent. But, if there is a substantial change in the color then it may be the result of the faulty printhead or RIP software.
Solution
In order to correct incorrect color or color crosstalk, you must use high-quality ink, print head, and needle.
4. The Nozzle Does not Inkjet
Your wall printer is performing the pumping operation but the inkjet is not ejecting properly. If it is what you are facing then the problem is most likely a blocked printhead.
Some of the most common causes of the blocked print head in a wall printing machine are:
Dried ink: If the ink in the print head dries out, it can cause a blockage. This can happen if the printer has been sitting unused for an extended period of time.
Low-quality ink: Using low-quality ink can cause the print head to become clogged. This is because low-quality ink often contains impurities that can build up and cause blockages.
Infrequent cleaning: Regular cleaning is necessary to prevent blockages in the print head. If it is not cleaned regularly, it can become clogged with dried ink or debris.
Environmental factors: Environmental factors, such as humidity or dust, can also contribute to a blocked print head. These factors can cause the ink to dry out or debris to accumulate in the print head.
Damaged print head: If your print head is damaged, it can also cause blockages, preventing the nozzle from ejecting inkjet.
Solution
To prevent a blocked print head, it’s essential to use high-quality ink, clean the print head regularly, and store your printer in a clean and dry environment. If you do experience a blockage, try soaking the print head in a cleaning solution and use a soft brush to gently clean the needle.
5. Body Shaking of a Vertical Wall Printer
The wall printer moves mainly in two directions of the print head — horizontal and vertical. If your printer senses the wall is uneven, it is constantly trying to adjust the distance from the wall. This causes the machine to shake resulting in inaccurate prints and uneven lines.
In the case of outdoor printing strong winds can cause the machine to shake and cause the ink to splatter leading to lower-quality print outcomes. In some cases, it can even damage the printer or cause it to malfunction.
Solution
To prevent shaking, make sure you have a stable and level surface for your wall printer. Using a sturdy stand or mounting system, increasing the machine’s counterweight can reduce this problem.
6. Bad Print Accuracy
No matter what you try, the prints are not accurate enough and the details are not stunning. This can be caused by several factors listed below:
Print head misalignment: The print head in a wall printer must be aligned correctly to produce accurate prints. If the print head is misaligned, it can cause the printer to print inaccurately.
Ink supply issues: If the ink supply in the printer is running low or is inconsistent, it can cause inaccurate printing. The ink levels should be checked regularly, and the ink supply should be maintained properly.
Dirty print head: A dirty print head can also cause inaccurate printing. Over time, ink can build up on the print head, leading to clogs and other issues that can affect print accuracy.
Low-quality ink: Using low-quality ink can also cause bad print accuracy. Low-quality ink may not be compatible with your printer, leading to issues with ink flow and consistency.
Incorrect print settings: Incorrect print settings, such as print speed or resolution, can also affect print accuracy. It’s essential to ensure that the print settings are correctly set up for the specific project to achieve the desired print accuracy.
Technology and quality of printer: The technology and quality of a wall printer can have a significant impact on print accuracy. The use of professional RIP software can sometimes restore the original color. Besides, other factors like advanced print head technology, ink delivery systems, and calibration tools can also affect the accuracy of prints.
Solution
Clean and maintain your print head, use high-quality ink, and ensure your printer is set up correctly to improve print accuracy. If the issue persists contact a professional for assistance.
