Using the Broach
WARNING: Improper use of a broach can damage
the printhead membrane.
1. Make sure the broach pin does not extend out of
the handle any more than 0.10 inch. This will
ensure that the broach pin will not poke a hole
in the membrane and cause internal leaking.
2. Wipe the front plate clean with a cloth and con-
ditioner.
3. Identify the clogged orifice by identifying the
missing dot(s) from a print sample.
4. Count the orifices on the front plate up or down
until you locate the clogged orifice. A flashlight
or other concentrated light source will help, as
the orifices are very small.
5. Carefully insert the broach pin in the clogged
orifice until the handle touches the front plate.
Remove the broach pin from the orifice and cre-
ate a print sample.
NOTE: Avoid broaching repeatedly. The broach
pin is like a microscopic file that with repeated
insertions will enlarge the orifice. The enlarged
orifice will seep ink, print off target, or produce
other print anomalies.
6. If the print sample shows that the orifice is still
clogged, purge the printhead and make a sec-
ond print sample.
7. If orifice is still clogged, count the orifices again
to make sure that you are broaching the correct
orifice.
8. If orifice is still clogged, repeat steps 5 to 6.
