Cleaning the Print Head

Cleaning the Print Head
If your printouts are unexpectedly light or faint, or you notice light or dark bands
across your printout, you may need to clean the print head. This unclogs the
nozzles so they can deliver ink properly. Run a nozzle check as described on
page 30 to see if the print head needs cleaning.
Note:
Print head cleaning uses ink, so clean it only if quality declines and the nozzle check
indicates that the print head needs to be cleaned.
If the red
B
i
nk light comes on or flashes, you cannot clean the print head. In this case,
replace the appropriate ink cartridge first. (See page 32.)
1. Make sure the Stylus CX is on and the B ink light is off.
2. Hold down the
B
ink button for 3 seconds until the
On
light starts flashing.
The CX4500 runs a head cleaning cycle and the
On
light flashes.
Caution:
Never turn off the Stylus CX while head cleaning is in progress. You may
damage it.
3. When the
On
light stops flashing, run a nozzle check (as described on
page 30) to verify that the print head is clean.
4. If there are still gaps or the test patterns are faint, run another cleaning cycle
and check the nozzles again.
Note:
If you don’t see any improvement after cleaning the print head four or five times,
turn off the CX4500 and wait overnight. This lets any dried ink soften. Then try
cleaning the print head again. If quality still does not improve, one of the ink
cartridges may be old or damaged and needs to be replaced. See the next section.
Tip:
If you do not use your Stylus CX often, it is a good idea to print a few pages at least
once a month to maintain good print quality.
