Anyone know where I can find a Canon MP980 service manual - specifically instructions for replacing the ink absorption unit?

I've tried all the usual searches but all I come up with is user manuals or service manual for other models.

Thanks

If the ink absorber alone needs to be replaced (because the ink absorber becomes full, etc.) and no other engine parts are replaced, the ink absorber can be replaced only by separating the print unit from the bottom case. It is not necessary to disassemble the whole engine unit.

1) Disconnect the DC harness from the logic board (right side of the machine).
2) Disconnect the ground cable from the front chassis (left side of the machine).
3) Remove a total of 6 screws that fix the switch system unit to the bottom case, and the purge drive system unit to the bottom case.
4) Slowly lift the print unit to separate it from the bottom case.
5) Remove the paper separation slope, since a portion of the ink absorber lies under it.
6) Replace the ink absorber. Confirm that the replaced new ink absorber completely fits in place and is not lifted or dislocated, especially under the pump.
7) While being cautious of the ink tube and each harness location, return the print unit to the bottom case, and fasten the screws (6 screws removed in step 2).
8) Properly arrange and connect the harnesses, install the scanner unit, and attach the document pressure plate unit and external housing.

Thanks.

I'd already found this on the Apple Discussions (I think). However if you actually have the printer in front of you you will understand that there's a whole load of instructions missing that actually get you to the point where you can see the DC harness let alone where it unplugs...
