You could just turn the ink refill monitor off.

Open the Windows Start menu, open the "Canon Utilities" folder, open the "My Printer" folder, open "My Printer", click on "Printer Status", go to the "Options" menu, unselect "Enable Status Monitor".

You should be able to tell when your ink is low, because the color will fade.

I have a canon printer MP190. How do I do the reset after completing my ink cartridge to the syringe?

SOURCE: Canon MP560 ink level override

I have the same problem, BUT once the printer detects the cartridge is either empty OR replaced by a generic, it does NOT print at all. It freezes up and refuses to do anything (scan to USB, scan to PC, scan to PC application) until you put in a genuine Canon cartridge. My previous iP PIXMA 4000 the MP560 replaced worked fine with generic cartridge refills. Had for 5 years. But the MP560 is smarter. How can you override this problem? Thanks TDK
