Note:
❏

Print head cleaning uses both color and black ink. To avoid wasting
ink, clean the print head only if print quality declines.

❏

Use the Nozzle Check utility to confirm that the print head needs to
be cleaned. This saves ink.

❏

When the

B or

A ink out light is flashing or on, you cannot clean

the print head. Replace the appropriate ink cartridge first.

❏

Do not start the Head Cleaning or Nozzle Check utility while
printing is in progress; otherwise your printout may be marred.

1. Make sure that the

P power light is on and that both the

and

A ink out lights are off.

Note:
If the

B or

A ink out light is flashing or on, you cannot clean the

head, and this operation will start the ink cartridge replacement
procedure. If you do not want to replace an ink cartridge at this
moment, press the

cleaning button to return the print head to

its home position.

2. Hold down the

cleaning button for three seconds.

The printer starts cleaning the print head and the

P power

light begins flashing. Print head cleaning takes about one
minute to complete.

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 few lines from

a document to confirm that the head is clean and to reset the
cleaning cycle.
