Try a different ink cartridge. If that doesn't solve it, use Canon brand ink. This machine does not like junk ink.

hi...you can try to press the reset button in five second.,.,

The error usually came out after you refill ink on the black cartridge...there is no way you can make the printer work without resetting the ink cartridge..

Try to reset the printer using this procedure.. it will help.
1. turn off the printer..
2. press/hold the stop/reset button..and press/hold power button too..
3 while holding power button, release the stop/reset button..
4. then press the stop/reset button twice..
5. release power button..and wait until the power button lights a steady/still green and says "idle"...
6. open the cover...take out both catridges.. then turn off the printer.
7.put back the cover then turn on...
8. now put the catridges back.. and wait for some time to return to display menu... then try to print...

The printer may still prompt a "black ink volume unknown and color ink volume unknown" but don't worry that won't affect the operation of the printer. And you will able to use your printer, fax and scanner.

Do this every time you refill the ink of the cartridges.

Same thing happened to my MP220. U051 chk Blk and Colour. I got my colour one replaced as there was an electrical fault in it. So the solution is to replace whichever one has the electrical fault or both and it works just fine. Refilling only works for a certain number of times. 4 or 5 at most and mine only lasted 1, so not always successful.

when the message appears, hold the reset button for about 5 seconds, this disables ink monitor on most canon models
