Cleaning The Print Head - Canon Pixma MG3550 Online Manual

Cleaning the Print Head

Clean the print head if lines are missing or if horizontal white streaks are present in the printed nozzle check pattern.
Cleaning unclogs the nozzles and restores the print head condition. Cleaning the print head consumes ink, so clean the
print head only when necessary.
1. Make sure that the power is turned on.
2. Hold down the Stop button until the Alarm lamp flashes orange twice, then release it
immediately.
The machine starts cleaning the print head.
The cleaning will be complete when the ON lamp lights green after flashing.
Do not perform any other operations until the machine completes the cleaning of the print head. This takes about 1 to
2 minutes.
3. Check the print head condition.
To check the print head condition, print the nozzle check pattern.
