Canon MP780 Waste Ink Tank Reset Procedure

[ghwellsjr]

This information has been posted elsewhere but it was unnecessarily confusing so I'm making my own set of easy-to-follow instructions:

1) Press the following keys in sequence: Copy-Menu-Scan-Copy-Scan.
The display will say:
SERVICE MODE
#1 SSSW

2) Press the > key (also labeled +) six times.
The display will say:
SERVICE MODE
#7 PRINTER

3) Press OK.
The display will say:
#7 PRINTER
#1 SSSW

4) Press the > key (also labeled +) four times.
The display will say:
#7 PRINTER
#5 INK ABS CAPA

5) Press OK.
The display will say:
SUCTION
XX (where XX is how full the waste ink tank is as an integer percentage)

6) Change the XX to 0 by entering 0.
The display will say:
SUCTION
0

7) Press OK.
The display will momentarily say:
SUCTION
DATA ENTRY OK
and then will quickly change to:
#7 PRINTER
#6 CDR ADJUST

8) Press the Stop/Reset button

And the printer is back to normal.

Thanks for the info.

Do you know the procedure for the MP980 please ?

No, I steer clear of printers that use chipped cartridges. But if anyone else knows that answer, they should start a new thread because no one will ever find it on this one.
