Here is what Canon says on their website:
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 by pressing the <Resume> button on the printer. 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.

It doesn't matter if you change (wash) the waste ink pad absorber or not, if you reset the error code il will work ok. The waste ink sponge can be full if you had a lot of cleaning done since using the printer, fact is that latest after the error appears the second time, you had to clean it.

1) Figure out how to open the printer by removing the side and inside top plastic panels. Just look at the thing and use your brain. Its all pressure clipped in place, no screws (at least on the S900 and similar models, probably still the same on this years models.) Look for slots and triangles on the 960.

On the i960 you'll have to remove the power buttons assembly on the front- take out the two screws, unplug the internal white electro connector plug CAREFULLY, then you can undo the last clip that holds the top in place.

2) No need to remove the ink cartridges in this process- so don't. The mechanism is held down in place in the case by two screws at the very bottom on the outside bottom of the metal chassis inside. Remove these screws then lift up the mechanism. It should lift out fairly easily, but remain attached by wires-- just place it on the top edge of the case.

3) You'll see the blackened (from waste ink) felt pads on the bottom. WEAR GLOVES-- this is skin indelible ink, the only thing that will get it off your hands is CLOROX. Period. There are two skinny pads that sit on top of a larger pad. Note how they fit together.

4) Lift the pads out and rinse out thorough in a sink until very little or no ink comes out. There's no need to use chemical or soap cleaners, just use plain water from the tap and the spray nozzle. Keep rinsing and squeezing the pads, but don't twist them like a towel, squeeze and fold in half however to really get the ink out.

Lay flat in the sun for a few hours to dry. Use a hairdryer to get the last bit of moisture out then replace in the printer, and put everything back together.

5) RESET the printer electronics, so you won't get the stupid "waste ink tank full" message any more.

Your color cartridge may be old. Also check the printer properties and make sure that the settings are set properly. Usually default will do all right.
