Canon iPF780 Printer User Manual


 
Use this mode if printing is faint or contains foreign substances. This method of cleaning consumes the least
amount of ink.
Head Cleaning B
Use this mode if no ink is ejected at all, or if Head Cleaning A does not solve the problem.
Important
Do not remove the Maintenance Cartridge or ink tanks during either Head Cleaning A or Head Cleaning B.
Ink may leak or an error may occur.
If printing does not improve even if you execute Head Cleaning B, try repeating Head Cleaning B once or twice.
If this still does not improve printing, the Printhead may have reached the end of its useful life. Contact your Can-
on dealer for assistance.
Note
By default, nozzles are checked at fixed intervals.
Configure the settings on the Control Panel menu in Nozzle Check.
