Edible Printhead Maintenance Tips


Print Head Maintenance: Canon Edible Printer

While having the ability to refill an ink cartridge and enjoy almost-free prints, it's frustrating when your refill isn’t working correctly.  If a printer is printing, but the output is blank or has poor image quality, it is often due to clogging. Not all bad prints are caused by clogging.  An aging printhead may cause the problem as well in severe cases you may need to change the printhead.

Every time, you do not need to visit any printer repair shop. This printhead maintenance guide is created to help you resolve clogged or choked printhead issues.

What is Printhead 

What a printer is supposed to do? The answer is “printing.” Printhead performs that principal role by transferring the minute droplets of ink through its numerous nozzles on the sheet to create the desired image. Blockage in the nozzles, which may happen over time due to factors discussed below, obstruct the smooth flow of ink. This diminishes the print quality, and when left without troubleshooting, it may slow damage the printhead itself.

What Causes Clogging of a Print Head

  1. The high viscosity of edible ink
  2. Crystallization of the ink ingredients or matter particles like sugar due to temperature as low as 18 °C (64.4°F)
  3. Sedimentation or deposition of ink ingredients in the nozzle due to idleness of the cartridge or the machine
  4. Placement of the printer in a cold environment near the window that clogs the printhead

How to identify a clogged printhead? 

A clogged printhead affects the print quality or resolution badly. There could be shadowy, streaky or spotty print despite having an appropriate level of ink in the cartridge. It’s quite frustrating. Your printhead needs maintenance. To confirm the printhead issues, run Print Nozzle Pattern test using your Canon Printer Settings as follows: Go to Setting Or Gear  icon on the printer LCD screen, tap Maintenance, and then “Print Nozzle Pattern

Use plain A4 size sheet in the FRONT Cassette of your Printer. Do not waste frosting sheets or wafer paper for test prints. The print quality itself confirms the problem.

Cleaning the Printhead

 Check this image of a printhead. It has a black compressed rubber seal/washer. If the washer does not return to its full size, it needs to be removed and cleaned. A "poor seal" fails to keep the colors separated and results in clogging.
