How to Reset the Canon Pro9000 Ink Chip

Updated November 21, 2016

The ink cartridges in some models of Canon printers, such as the PIXMA Pro9000, come with ink level sensors. These chips can be a problem if you refill your ink cartridges, as the chip will not recognise that the cartridge has been refilled and will keep telling the printer that your ink cartridge is empty. You can fix this problem in one of two ways: purchase a chip resetter, or disable the ink level monitor completely.

Purchase a chip resetter that will accommodate PIXMA Pro9000 ink cartridges.

Connect the recently refilled cartridge to the chip resetter cradle. Gently press down and hold.

Wait until the LED light on the ink cartridge flashes. When it flashes, the ink chip has been reset.

Connect your printer to your computer, and select a document to print.

Select "OK" when the low ink level warning box pops up.

Select "Yes" in the next box to turn off ink level monitoring.

Select "Yes" in the next box warning against potential damage to the printer. The cartridge has been refilled and has ink.

Press and hold the "Resume" button on the printer for five seconds when you are instructed to do so.
