2. Hold down the R cleaning button for three seconds.
3. The printer starts cleaning the print head and the P power light
begins flashing. Print head cleaning takes about one minutes to
complete.
c Caution:
Never turn off the printer while the
P power light is flashing.
Doing so may damage the printer.
4. When the P power light stops flashing, print a few lines from a
document to confirm that the head is clean and reset the cleaning
cycle.
If print quality hasn’t 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.
To replace an ink cartridge before it is empty, see “Ink cartridge
problems” on page 20.
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.
