MX340. What is the override trick when I want to scan but one of the ink cartridges is missing. Holding the stop or either start button for more than 5 seconds seems not to do it.

Don't use refill cartridges, because it will damage your printer someday. and will cost your parts as brand new. so better use the original ink.

SOURCE: Refilling Ink in Canon Pixma MP830

Hello, I found this in a repair manual for the MP830. summery is to press and hold the stop/reset button for 5 or more seconds. I copied the info from the manual too. The remaining ink amount unknown. [1683] (Applicable ink tank icon) The remaining level of the following ink cannot be correctly detected. An ink tank which has once been empty is installed. Replace the applicable ink tank with a new one. Printing with a once-empty or refilled ink tank can damage the print head. If printing is continued without replacing the refilled ink tank, press the Stop/Reset button for 5 sec. or longer to record the use of a refilled ink tank. Note: After the above operation, the function to detect the remaining ink amount is disabled.

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
