Control panel message Description Recommended action
Replace Staple Cartridge The control panel indicates that the stapler
is out of staples; however, after putting in a
new cartridge, the message remains.
The signal is generated by sensor PHOI2
(staple-ready sensor) or sensor PHOI3
(staple-level sensor). Both are located in
the stapler assembly and cannot be
cleaned or serviced.
1. Make sure that a genuine HP staple
cartridge is being used.
2. Replace the staple cartridge.
NOTE Staples come pre-
loaded in the staple cartridge
and cannot be ordered
separately as a refill from HP.
3. Check the wiring connections at the
stapler assembly.
4. Remove the stapler assembly and any
loose staples found in and around
stapling assembly.
5. If none of the above corrects the
problem, replace the stapler assembly.
6. Check wiring connection J1312 on the
stapler/stacker driver board.
7. If none of the above corrects the
problem, replace the stapler/stacker
unit.
Stapler Low On Staples The control panel indicates that the stapler
is low on staples or the staple cartridge is
missing; however, after putting in a new
cartridge, the message remains.
The signal is generated by sensor PHOI3
(staple-level sensor). Sensor PHOI3 is
located in the stapler assembly and cannot
be cleaned or serviced.

Too Many Pages In Job To Staple When the firmware detects that the job is
attempting to staple more than the
maximum 30 pages, the firmware signals
the jogger guides to open, dropping the
unstapled stack of paper into the output
tray below. The remainder of the copies will
print out and be directed to the output tray
without being stapled.
Do not attempt to staple more than 30
pages of 20 lb bond (75g/m
2
) paper. For
heavier paper, the maximum stack height
that can be stapled is 3 mm.
