Paper feed service checks
Paper picks and advances approximately four inches
FRU
Action
Reference feed
assembly
Backup roller assembly
Paper feed gear
Drive assembly
Turn printer off and remove the print cartridge
and left side cover.
With a left finger, rotate the main motor
counterclockwise while using a right finger to
resist gear movement in the reference feed
assembly (located in the paper path below the
cartridge).
If the gear motion cannot be stopped, look
for obstructions in the paper path, such as
debris or damage.
If the gear motion can be stopped while
continuing to rotate the drive motor, one of
the following units has to be replaced.
Check or replace the FRUs in the following
order:
– Backup roller assemblies
– Reference feed assembly
– Drive assembly
When the reference feed assembly is replaced,
it has to be adjusted. See
“Adjusting paper
feed alignment (skew)” on page 4-5
for more
information.
