Reset Your MP170

There is no way to actually "reset" the counter.
IF your MP170 has a RESUME/CANCEL button, Press and hold this button for about 7 seconds to bypass the counter (The PAGE FEED button will work for some other models). If your printer doesn’t have this button, you may bypass the counter by turning the printer OFF. Now hold down the RESET and turn the printer ON. Keep holding the RESET until the printer boots and initializes. When the display says, "INK VOL UNKNOWN" you may release the RESET and begin printing in the usual manner. You may need to start the printer in this manner each time, or the printer may remember this setting until such time as you replace the print cartridge. Canon was experimenting during this time so some of the same models have different buttons and bypass tricks. Hope this helps. Prophesser at Cactus Computer Consultants.

Simple to Reset MP390 Waste ink tank full

I actually don't know anything, except that I followed these directions. It worked for me. The sponge the original guy spoke about is not the waste ink sponge and cleaning it will not solve your problem. I ordered the pads and they are thick felt pads about 1/2 inch thick and about 5"X 2". You cannot access them without taking apart the printer. I have not done that yet as I'm afraid I might never get it back together again. So I'm continuing until it overflows. At that time I will take it apart with my camera to take detailed pics. I will post it if it works. If not, I will post the pic of my printer in the landfill. So the directions for resetting the counter is as follows. Spelling errors are not mine.

1)Printer on, press Additional Functions, Scan, Copy, Scan
Now you should be in service mode from there for waste ink tank reset

2)Select Test mode which is like the last avalabe selection
3)Select #8 Printer Test, it will do something here like cleaning or something then it will come up with some other option this is where it gets a bit confusing cause now all it says is like 8-2 or 8-3 push the + or - button until it says 8-3 then hit the select button

The menu will now say EEPRON Clear
Select Ink count which is option (0) and press set

Then press Stop/Reset Followed by the power button and then wait for it to restart.
