Cause Corrective Action
Many full-page color images are
printed. In print jobs such as photos, images are filled with color. This consumes a lot of ink. This does not
indicate a problem with the printer.
Head Cleaning B in the Control
Panel menu is executed frequent-
ly.
Head Cleaning B in the Control Panel menu consumes a lot of ink. This does not indicate a prob-
lem with the printer. Unless the printer has been moved or stored for a long period or you are trou-
bleshooting Printhead problems, we recommend not performing
Head Cleaning B , to the extent
possible.
You have just finished initial instal-
lation, when more ink is con-
sumed to fill the system. After initial installation or at the first-time use after transfer, ink flows into the system between the
Ink Tank and Printhead.
Although the amount of remaining ink may drop as a result, it does not indicate a problem.
The Printhead nozzles are clog-
ged. Check for nozzle clogging.
(See "Checking for Nozzle Clogging.")

Ink Level Detection
Ink Level Detection
Ink level detection will be deactivated if you load ink tanks once emptied.
Ink level detection
Ink tanks specified for this printer feature an ink level detection function to prevent the ink from running out during print-
ing, which prevents printer damage.
(See "Ink Tanks.")
➔
P.538
This function will not work correctly if you use refill ink tanks. As a result, printing stops. Thus, before using refill ink
tanks, you must cancel the ink level detection.
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.
Important
• After ink level detection has been released, this function cannot be reactivated for currently loaded Ink Tank. To use
ink level detection again, replace the Ink Tank with new ones specified for use with the printer.
• Repeatedly removing and inserting an Ink Tank may damage the connection between the Ink Tank and the printer,
which may cause ink leakage from the Ink Tank and damage the printer.
