Error E05 in Canon printers occur due to the compatibility issue of ink cartridge installed in your printer. This Error E05 also occurs if Ink Cartridge is not installed or fitted properly. Ink Cartridge in Canon printers has a small opening through which it discharges the ink to be utilized on a certain paper, therefore, when the printer is not getting used for a considerable period, the ink may get dried up & block the cartridge opening. Error E05 can also be caused by the disarrangement of a cartridge in its holder section, or when the cartridge needs to be replaced. This issue is common and can be solved easily.
