Possible Solution #1: reset the printer
  1. Unplug yor printer from the wall outlet, and unplug the power cord from the printer too.
  2. Wait 60 seconds
  3. Replug the printer and turn it on
If that does not solve the problem, I am afraid you need to change the Ink Absorber. Here is the info from Canon:

"Ink Absorber Replacement Options

This printer has an ink absorber that takes in ink during the printing and print head cleaning processes. The cleaning process is necessary in order to keep the print head nozzles from becoming clogged. Over the life of the printer, the amount of ink that the ink absorber has absorbed is calculated by the printer. Eventually, after substantial use, the printer will enter an error condition when the ink absorber is nearly full. At this point, printing is still possible. Press the button to cancel the error. You will still be able to print for a short period. To protect the printer from damage, you will not be able to print at all once the ink absorber is full.


Canon recommends having the printer serviced before the absorber becomes full. We are aware that there are many "do-it-yourself" Web sites that offer instructions for making this repair. Replacing the ink absorber is a complicated and potentially messy procedure. Even if the ink absorber is successfully changed, the ink absorber counter must be reset. Be aware that if you attempt this procedure, it is at your own risk.


If you feel your product might require service, Canon has excellent service options, and we are eager to provide any assistance you may need. Click the link below to locate an authorized service facility and obtain further instructions.

I have already tried this. Sorry, but this was no help and not worth the $14
Expert:  Engineer John C. replied 7 years ago.

As I told in my previous reply, if resetting the printer does not solve the issue, you will need to service the printer to change the Ink Absorber.


Over the life of the printer, the amount of ink that the ink absorber has absorbed increase and you will need to change the absorber. That has to be performed by a Canon Service Center.


If your printer has the warranty expired, they will charge only $9.99 to change the Ink Absorber.


In my last reply you have the contact numbers and a link to find a close Canon service location.


If still you think this help is not worth the $14 you can ask for a refund here:


Also, if you think I don't deserve a positive feedback please DO NOT click the Accept button.


I wish you a Merry Christmas.


Thank you
