Step Actions and questions Yes No
1 Remove the stapler cartridge holder from the stapler
assembly. If the holder is jammed in the stapler
assembly:
1. Turn the printer off, and remove the right side
cover. Use care when removing the cover, as the
right side door switch and cable assembly are
easily damaged. Do not allow the right side cover to
hang by the switch and cable assembly.
2. Disconnect the 10-pin cable from the stapler
assembly.
3. Hold the stapler assembly with one hand while
removing the three screws from the assembly. The
assembly is heavy and easy to drop.
4. Check the stapler assembly for damaged or broken
parts. Check the flag and spring assembly on the
front of the stapler assembly to see if the flag or
spring are broken or missing.
Is the flag or spring broken or missing?
Replace the
broken or
missing flag or
spring. Go to step 2
2 Carefully cycle the large gear on the side of the stapler
assembly, and try to free the cartridge holder
assembly. Note: Look for staples jammed at the throat
of the cartridge holder, and remove any that are found.
Gently try to remove the cartridge holder from the
stapler assembly. It may be necessary to manually
cycle the large gear on the side of the stapler assembly
to release the cartridge holder.
Reinstall the stapler assembly with a new stapler
cartridge holder and staples. Run the Finisher Feed
Test to check the option. See
“Finisher Feed Test”
on page 3-23 .
