Maintenance
8-9
The printer starts cleaning the print head and the
P
power
light begins flashing. Print head cleaning takes about thirty
seconds to complete.
c
Caution:
Never turn off the printer while the
P
power light is flashing.
Doing so may damage the printer.
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 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 “Replacing an
Empty Ink Cartridge” on page 7-2.
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.
Aligning the Print Head
If you notice a misalignment of vertical lines, you may be able to
solve this problem from your computer using the Print Head
Alignment utility in your printer software. Follow the directions
