Question about Canon PIXMA MP780 All-In-One InkJet Printer
Dear mr perfect,
Few days ago I have answered the same question about this for Canon MP700. Here is my answer:
Waste ink absorber capacity of your printer has rise to about 90-95 %. Tentatively, you can continue printing by pressing STOP/RESET button. When ink absorber capacity reach about 100%, the printer stop working and message 'Waste Ink Tank is Full' appears.
To fix this problem, you need to reset waste ink counter. It strongly recommended that you replace waste ink absorber after resetting waste ink counter.
Here are steps resetting waste ink counter of this printer:

Canon's a little shady when it comes to this, since any waste ink pad I've seen never has been more than 30-40% full. You can reset that status without cleaning the waste ink out and the printer should return to normal.
1) On the printer, press Additional Functions, Scan, Copy, Scan. This will put you in service mode.
2) Select Test mode at the bottom
3) Select #8 Printer Test, wait for more options. It should say 8-2 or 8-3; push the + or - button until it says 8-3 then hit Select. The menu will now say EEPRON Clear
4) Select Ink count which is option (0) and press set
5) Press Stop/Reset, then the power button and wait for it to restart.
I hope this helps!

Under the place where the inks park is a tray full of asorbent pads. It was the most awful thing to get to in my Pixma ip 2000. If you have a day to spare, and a work table, and some long needle nose pliers or maybe hemostats, and the usual tools, you can take the machine apart to get at it. Note which pads (and parts) go where, everything has to go back where it came from. The pads will rinse out with water, lots of it.

5) Select 0. [INK COUNT].
6) Press the [OK] key.
7) Press the [Stop/Reset] key (returning to the state of 3)), and then press the [ON/OFF] key.
