Cleaning the Printhead may help clear nozzles that are clogged.

1. Press the Menu button to display MAIN MENU.

2. Press or to select Head Cleaning, and then press the button.

3. Press or to select the type of cleaning, and then press the OK button.

• 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 six 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 seven 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.
  
  

  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 the Canon Help Desk.

  
  Attention:
  Do not remove the Maintenance Cartridge or Ink Tanks during cleaning.
