Solve stapler/stacker problems
Control panel message Description Recommended action
There is no power to the stapler/stacker.
NOTE The stapler/stacker is
powered by the printer through the
communication cable connecting
the two devices.
1. Check the communication cable
between the stapler/stacker and the
printer for a loose connection or
damage. Make sure that the connector
is securely screwed in. If the cable is
damaged, go to step 4.
2. Check wiring connection J1301 on the
stapler/stacker driver board.
3. Replace the stapler/stacker driver
board.
4. If none of the above corrects the
problem, replace the stapler/stacker
unit.
13.12.07 Jam In Stapler The stapler could not finish its cycle but
was able to return to the home position
If the stapler drive does not return to home
position (HP) during the normal cycle, the
stapler/stacker driver signals M1304
(stapler motor) to rotate once in reverse. If
the HP signal is now detected, the stapler/
stacker driver sends a signal to the
formatter that a staple jam is present.
1. Remove the staple cartridge and any
loose staples or staples that might be
obstructing stapler movement.
2. Remove one sheet of staples from
staple cartridge and try again.
3. Inspect the staple cartridge for
damage. Replace the staple cartridge
if it is damaged.
4. Verify that genuine HP staples are
being used.
NOTE Staples come pre-
loaded in the staple cartridge
and cannot be ordered
separately as a refill from HP.
5. Remove the stapler assembly. Inspect
the stapler for jammed staples around
the staple plunger and crimper.
Remove any jammed staples that are
found.
6. Install a new staple cartridge.
7. Replace the stapler assembly.
8. If none of the above corrects problem,
replace the stapler/stacker unit.
13.12.08 Jam In Left Accessory Stay jam in accumulator. Paper sensor PS
1302 stayed activated longer than expected.
This signal is generated by sensor PS1302
(delivery sensor). PS1302 is located just
before the delivery rollers. In order to reach
or see the sensor arm, lift the upper
delivery rollers and upper paper-path guide
plate. You will now be able to see and
toggle the sensor arm activating PS1302.
1. Remove any jammed paper
obstructing the paper path to the
delivery rollers.
2. Check the delivery flappers and
linkages to make sure flappers are not
blocking paper from exiting the
machine to the output tray. If broken
parts are found, go to step 6.
