Cleaning the Print Heads
If print quality diminishes, use the printer’s built-in print head cleaning
cycle to ensure that the nozzles are delivering ink properly. You must
clean the color and black print heads separately.
To avoid wasting ink, clean the print heads only if print quality declines.
1. Make sure the printer is on.
2. Make sure the output tray at the front of the printer is lowered; then
open the printer cover. You see the
;
and
:
cleaning buttons.
3. Make sure the corresponding light for the print head you want to clean
is off.
Note:
If the
* or ) ink out light is on or flashing, this operation will start the ink
cartridge replacement procedure. If you do not want to replace an ink
cartridge at this time, press the
-
load/eject button to return the print heads
to their home position.
4. Press the
;
or
:
cleaning button for three seconds to clean the black or
color print head. The printer starts cleaning the print head and the
2
power light begins flashing. If you want to clean the other print head,
wait until the
2 power light stops flashing, then press the other
cleaning button (
;
or
:
) for three seconds. It takes about two
minutes to clean each print head.
c
Caution:
Never turn off the printer while the
2 power light is flashing. Doing
so may damage the printer.
Note:
You cannot clean both black and color print heads at the same time.
5. Close the printer cover.
