Cleaning the Printhead

Cleaning the Printhead may help clear nozzles that are clogged.
Choose one of two Printhead cleaning modes ( Head Cleaning A or Head Cleaning B ), depending on the problem to
resolve.
Note
• You can specify a number of pages in the printer's Noz. Check Freq. menu for automatic nozzle check-
ing and cleaning every time you finish printing that quantity. (See "Main Menu Settings.")
• You can start Head Cleaning A by holding down the Information button for three seconds or more.
Cleaning the Printhead
Note
• If printing does not improve after Head Cleaning A, try Head Cleaning B. If this does not solve the
problem, repeat Head Cleaning B one or two times. If this still does not improve printing, the Printhead
may have reached the end of its useful life. Contact your Canon dealer.
Caution
• Do not remove the Maintenance Cartridge or Ink Tank during cleaning.
