How do we change the waste ink absorber in a cannon inkjet printer? Thank you

Unplug printer, open top of the printer lid ,Once the case is off, you're looking at the guts of the printer sitting in the tray-like base. To get at the blotters and waste ink, you'll need to get under the printer body, which is held to the base by three or four screws. The older your printer is, the easier it will be to find the screws that hold the body to the base If you have a good magnetic screwdriver, that will be very helpful. It may also be helpful to take notes and/or pictures of where the screws are located to make re-assembly easier ,you will find small pads ( about 3/8 x 1 inch)under where the ink cartridges sit. They are grundgy, so I take them out, clean it with a kleenex or replace as in the case , clean out the slot that they sit in before replacing the pads. hope this helps

The pads under the printhead are just filters for the purge assembly, cleaning doesn't help. The actual ink absorbers are 1 inch thick and cover the entire bottom under the print engine. Your instructions are useless unless they have access to the service mode to reset the error, you will be reported for giving false misleading info. about as expert as a june bug...
