Canon GPR-44 Black Toner (2pcs/3.4K)

Getting blank pages after you installed a new cartridge? Check that the sticker from the cartridge was properly removed. Alternatively, run the clean print head function to make sure all air bubbles are removed. Do not remove the cartridge once it has been installed.

Most printers have a built-in diagnostics program which can be very useful for troubleshooting problems and test-printing without a computer. They are usually initiated by pressing a button or two while turning on the printer.

Are you getting diminished color and print quality? If all your images start to look a bit purple, blue or orange, one of your ink wells may be running low. Replace the whole printer ink cartridge, unless you can refill the individual ink wells.
