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.
Clean the Print Head.
(1) Press the (Maintenance) button repeatedly until H appears.
(2) Press the Black or Color button.
The machine starts cleaning the Print Head.
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.
When the cleaning is completed, the LED returns to the copy standby mode.
To check the print head condition, print the nozzle check pattern.
See Printing the Nozzle Check Pattern .
Note
If the problem is not resolved after cleaning the Print Head twice, clean the Print Head deeply.
See Cleaning the Print Head Deeply .
