Ink Level Detection
The printer ink tank detects the amount of ink remaining to prevent running out of ink while printing and to
avoid printer failure.
Ink Tanks
When using an ink tank refilled with ink, the function for detecting the remaining ink level may not operate
properly and printing may stop. If you want to use an ink tank refilled with ink, you need to disable the
function for detecting the remaining ink level.
Important
• Printing with the ink level detection canceled may lead to printer damage and printing problems. Canon •
Inc. is not liable for any damage that may occur as a result of refilling ink.
• Once the function for detecting the remaining ink level is disabled, it cannot be restored for that ink tank. •
To restore the function for detecting the remaining ink level, replace the ink tank with a new ink tank for
that printer.
• Repeatedly removing and inserting the same ink tank can cause the contacts between the ink tank and •
printer to malfunction, ink may leak from the ink tank, and the printer may become damaged.
Releasing ink level detection
Ink level detection will be deactivated if you load ink tanks once emptied.
If "The above ink tank may be an ink tank that ran out of genuine Canon ink or a counterfeit Canon ink
tank." appears on the touch screen, follow the steps below.

on the touch screen.

for at least 5 seconds, and then release it.
Ink level detection is now released.
