6-14 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.
1. 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.
2. 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.
3. 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.
4. 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).
