9-8 Maintenance
3. When the 
P
power light stops flashing, print a nozzle check 
pattern to confirm that the head is clean and to reset the 
cleaning cycle.
If print quality has not improved after repeating this procedure 
four or five times, turn the printer off and leave it alone overnight. 
Then, do the head cleaning again.
If the print quality still has not improved, one or both of your ink 
cartridges may be old or damaged and may need to be replaced. 
See “Replacing Ink Cartridges” on page 8-1.
If print quality remains a problem after replacing the ink 
cartridges, contact your dealer.
Note:
To maintain print quality, we recommend turning on the printer for at 
least one minute every month.
