Ink Level Detection

Ink Level Detection
Ink level detection will be deactivated if you load ink tanks once emptied.
652
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.")
The following sounds do not indicate a problem with the printer.
•
There is a sound of suction from the Platen
To prevent paper from rising, paper is held against the Platen by suction from Vacuum holes under it.
•
There is a sound when a different size of paper is used and when the Carriage goes from side to side
When paper of a different size is used, a valve is automatically activated to switch the area for paper suction, which
may make a sound. This mechanism prevents suction from Vacuum holes where there is no paper.
In addition, ink is ejected in sync with the movement of the Carriage back and forth to ensure optimal ink flow. At
this time, the valve automatically switches the area for paper suction, which may make a sound.
• Roll paper makes a fluttering sound during printing
There may be a fluttering sound when large paper is advanced.
•
If you suddenly hear the tone for cleaning operations
At regular intervals, for printer maintenance, cleaning operations will begin automatically, even if the printer is in
Sleep mode.
•
If you suddenly hear the tone for ink agitation
At regular intervals, to ensure optimal printing quality, the ink is agitated automatically, even if the printer is in Sleep
mode.
The ink is also agitated automatically under the following conditions. Note that other operations are not possible
while "Agitating..." is displayed on the control panel.
•
After the printer is turned on
In other cases, contact your Canon dealer.
Cause
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 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.
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.
Check for nozzle clogging.
(See "Checking for Nozzle Clogging.")
Corrective Action
Remove the new Maintenance Cartridge you have just installed and insert it again
firmly.
(See "Replacing the Maintenance Cartridge.")
