Cleaning the Printhead
Cleaning the Printhead may help clear nozzles that are clogged.
Note

You can specify a number of pages in the printer's Noz. Check Freq. menu for automatic nozzle
checking and cleaning every time you nish printing that quantity. (→P.48)
•
You can start Head Cleaning A by holding down the Information button for three seconds or more.

Head Cleaning A
Use Head Cleaning A if printing is faint or contains foreign substances. This method of cleaning
consumes the least amount of ink. It takes about two minutes to complete.
•
Head Cleaning B
Use Head Cleaning B if no ink comes out of the printhead, or if Head Cleaning A does not solve the
problem. It takes about three minutes to complete.
The printhead is cleaned, and the printer goes online.
4.
Print a test pattern to check the nozzles, and determine whether cleaning has cleared the
nozzles. (→P.689)
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 at least 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 Tanks during cleaning.
