Ink-cartridge chips in Canon products serve several purposes. These uses include preventing the installation of third-party ink cartridges in Canon printers, and identifying errors and relaying error messages to the printer’s display. Most ink-cartridge problems arise from user errors such as improper installation. You can troubleshoot your Canon ink-cartridge chip by observing and understanding the error messages that appear on the printer’s display.
1. Remove the Canon ink cartridge from your printer. Power down the printer and unplug its power cord from the outlet. Wait a few seconds, then plug the printer in and power it up.
2. Install the ink cartridge in your printer. Wait two minutes for the cartridge to charge and initialize.
3. Check the printer’s display for an E5 error code. This error code in a Canon printer means that the ink cartridge was not installed properly. To clear this error, repeat the previous steps and install the cartridge properly, making sure the label on the cartridge is facing up.
4. Check the printer’s display for code E8 if you installed the ink cartridge properly and you cannot print. Code E8 indicates the platen waste-ink absorber is full. To clear an E8 error, open the printer’s protective cover until the print head moves all the way to the left. Power down the printer and unplug it from the power source. Remove the ink cartridge and the printer’s protective cover by pressing the two retaining clips on the sides. Using a pair of tweezers, remove the felt pads from the platen waste ink absorber; this tray lies under the ink-cartridge holder. Rinse the pads in warm water and pat them dry with paper towels. Allow the pads to air dry, and then repeat the disassembly steps in reverse to reinstall.
5. Check the printer’s display for code E4. This code means that the cartridge has no ink and needs to be replaced.
6. Check the printer’s display for error code E6502. This error indicates an ink-tank position error. To clear the error, reinstall your ink cartridge, making sure it is properly aligned in its holder.
