When do you need to replace the print head?


As a sublimation printer manufacturer, I would like to share with you the time it takes to replace a printhead. If your company has sublimation printers, it is important to clean and maintain the printheads. After all, if the printhead is damaged or clogged, your printer won’t work. Even with proper care and maintenance, printheads sometimes need to be replaced.

Even the cheapest inkjet printers have printheads. If the printhead of a home printer is broken, it is usually more economical to buy a new printer. With expensive sublimation printers, the cost of buying a new printer is prohibitively high every time the print head is damaged, which is why the printer should be replaced.

The printhead is supplied with ink from an ink cartridge; this ink is sprayed onto the paper using small nozzles. Piezoelectric inkjet printheads use electric charge and vibration to push ink out of the nozzles, while thermal inkjet printheads use heat to boil the ink and create ink vapor, which forces the ink vapor through the printhead’s nozzles.

As you can imagine, there are different cleaning and repair methods for different types of printheads, and different answers to the question of when to replace a printhead. Consult the printer manual and follow the manufacturer’s troubleshooting guide.

If you notice a drop in print quality, this may be a sign that the printhead needs to be replaced. Unfortunately, this can also be a sign that the printhead needs cleaning. How do you know which one is needed?

It’s simple: clean the printhead first. Your printing system may be clogged and needs to be thoroughly cleaned. Try loosening the printhead using our approved cleaning system. Run a cleaning cycle or two to remove any dry ink. If you’ve done this and still don’t see improvement, the next step is to replace the ink cartridges. These two steps should fix most printhead problems, but if they don’t, it’s time to replace the printhead.

Some printers make diagnosing printhead problems easier because they display printhead problems on the LCD screen. Of course, this is also a sign that the printhead may need to be replaced.

If you have a commercial or wide-format subliamtion printer, replacing the printhead requires some research. You’ll find seemingly endless options, confusing names and numbers, and it’s not always easy to find what you need. If you have any questions about the nozzle, you are welcome to consult us at any time, we will try our best to give you the most satisfactory answer.
