Phaser 300X Color Printer

Note

The

CLEAN PRINT HEAD

button performs two cleaning

operations: wipe or purge. During a wipe operation, the
printhead passes a wiper that removes paper fibers from the face of
the printhead. During a purge operation, the printhead expels ink
to flush air out of the ink-jet nozzles of the printhead.

Whether the

CLEAN PRINT HEAD

button does a wipe or purge

depends on the number of times you press the button and how
many prints you have made before you press the button again.

Press the

CLEAN PRINT HEAD

button one time. The printer

performs a wipe operation that removes any paper fiber that
might have accumulated on the printhead. When cleaning ends,
the

Ready

message appears in the front panel.

Press the

TEST PRINT

button to make a test print. If the print still

has missing lines, press the

CLEAN PRINT HEAD

button again.

The second time you press the

CLEAN PRINT HEAD

button, the

printer purges ink. When the purging operation ends, the
printer’s front panel displays the

Ready

message. You can then

make a print.

If the print still has missing lines, press the

CLEAN PRINT HEAD

button again. When you press the

CLEAN PRINT HEAD

button for

a third time, and you have made less than three prints since the
last time you pressed the

CLEAN PRINT HEAD

button, the printer

executes a longer purge.

Note

When you make three or more prints between successive pressings
of the

CLEAN PRINT HEAD

button, the cleaning cycle returns to

the first stage and wipes the printhead the next time you press the
button.

If your prints still have missing lines (after pressing the

CLEAN

PRINT HEAD

button three times), clean the wiper (see “Cleaning

the head wiper” on page 4-20).
