Many full-page color images are printed. In print jobs such as photos, images are lled with
color . This consumes a lot of ink. This does not
indicate a problem with the printer .
Head Cleaning B is used often. Head Cleaning B consumes a lot of ink. This does

or you are troubleshooting Printhead problems, we
recommend not performing Head Cleaning B , to the

Y ou have just nished initial installation, when more
ink is consumed to ll the system.
After initial installation or at the rst-time use after
transfer , ink ows into the system between the Ink
T ank and Printhead , which may cause the ink level
indicators to drop to 80%. This does not indicate a
problem with the printer .
Ink Level Detection
Ink level detection will be deactivated if you load ink tanks once emptied.
Ink level detection
Ink tanks specied for this printer feature an ink level detection function to prevent the ink from running out
during printing, which prevents printer damage. ( → P .507)
This function will not work correctly if you use rell ink tanks. As a result, printing stops. Thus, before using
rell 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 relling ink.
Caution
• After ink level detection has been disabled, this function cannot be reactivated for the currently loaded
Ink T ank . T o use ink level detection again, replace the Ink T ank with a new ink tank specied for use
with the printer .
• Repeatedly removing and inserting an Ink T ank may damage the connection between the Ink T ank and
the printer , which may cause ink leakage from the Ink T ank and damage the printer .
