- You can start Head Cleaning A by holding down the Information button for three seconds or more.
- Printhead cleaning is not possible if POP Board (1.5 mm [0.06 in] thick) is loaded in the Front Paper Feed Slot. Remove the paper before cleaning.
CAUTION
- Do not remove the Maintenance Cartridge or Ink Tanks during cleaning.

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.
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.
