Why clean the printheads and how?

Why Clean the Printheads

Inkjet printers are a wonderful invention, but they can be problematic if they are not cleaned regularly or properly. Most users will automatically blame the ink cartridge when printing is flawed. The reality, however, is that print flaws are almost never due to a faulty cartridge.

There are many reasons why printheads get blocked. Blockage is actually caused by the ink that dries or sets on the inside or outer surfaces of the printhead. Print nozzles can easily get clogged because of their microscopic size (smaller than the diameter of a human hair). Clogging usually manifests itself in the form of holes or lines in the print, incorrect color or, in extreme cases, in the total absence of print. That is why it is necessary to clean your printer’s printheads.


How to Clean Your Printer’s Printheads

Image quality suffers when printheads are clogged. You might see lines or smudged ink on the paper. Cleaning the printheads is a quick and straightforward process that will help you avoid such an inconvenience.


Follow these steps to clean your print heads

Note: These instructions are specifically intended for a Canon mx920 installed on a Windows operating system, but most printers work in the same way.

  1. Open the Control Panel via the Advanced user option or the Start menu, depending on your version of Windows.
  2. Choose Hardware and Sound or Devices and Printers. Which option you see depends on your version of Windows.
  3. Click on Devices and Printers or on Display Printers or Printers and Faxes installed.
  4. Find your printer and right-click it to access the printing preferences. If your device is also a fax, you might see two options. Select the one that mentions the printer.
  5. Open a maintenance or a cleaning option. The Canon MX920’s Printing preferences window has several tabs at the top of the screen. Choose “Maintenance.” Again, most printers should have a set of options that is very similar. In the case of a Canon MX920, the first button is used to clean the printheads. After choosing the Cleaning option, you might need to choose the set of nozzles that you want to unclog. The best option the one that cleans them all, such as “All Colors.”
  6. Make sure that the printer is on and that paper is loaded, then click Execute or Start, regardless of the option you have chosen to begin cleaning the printhead. You may get another screen pop up in which you confirm that you do want to print the check pattern.
  7. The printer will print a grid along the top as well as several bars of different colors. The grid and the colors might come out sharp and clear, or some of the check boxes in the grid could be missing and the colors scratched.
  8. If the print result corresponds to the sharp image, simply click on Exit to finish. If some areas in the grid are missing or if there are stripes in the print result, click Clean or any other option that allows you to start cleaning the printheads on your printer.
  9. Once this is done, repeat the entire process to ensure that the cleaning was completely successful.
  10. If you run the cleaning process twice but still get a poor result, some printers offer an in depth-cleaning option that should do the trick.
