17)Canon Error Messages

When your printer turns on it performs a check of the LED lights emitting from the cartridge chips. This is done when the cartridges are at the left most position. The LED light shines through the clear plastic of the cartridge to the sensor. If the sensors cannot detect the light the printer will produce an error message similar to the one pictured above. If this happens check the cartridges to make sure nothing physical impacting on the LED. The most common explanation is a missing LED, accidently cut off when removing the chips from the OEM cartridges

If one or more of your ink cartridges cannot be recognised, please ensure that the cartridges are clicked into position and/or the chips are correctly placed on the cartridges.

The most common cause of this issue is the blockage or damage of the LED as per page 9.

Ensure the printer lid is closed when checking cartridge recognition. Ambient light in some situations can affect the LED sensors. Failure to close the lid while testing can result in cartridge recognition error messages.

To check that the LED’s have not been damaged, bring the cartridges to the change position. Once in position unclick and re-click into position all the cartridges. If the LED light of a cartridge is not functioning (flashing or constant) it is most likely that the chip is faulty or damaged. In this case the chip may need to be replaced.

In unusual cases this message may appear if the chips have been mixed up and fitted to the incorrect CISS cartridge. (i.e. Yellow OEM cartridge chip on a Blue CISS cartridge). The solution in this case is to remove all chips and re-attach to OEM cartridges to identify which chip belongs to each coloured cartridge

Ensure that the printer senor has been pushed down and secured using a piece of blu-tack or tape as per section
