12-400/12-538 RAP
12-400: The Low Staple Sensor detects the Stapler is nearly empty.
12-538: The Stapler is empty. This fault is declared if 30 sets are stapled after 12-400 is
declared.
Initial Actions
Refer to BSD 12.13 for this procedure.
Procedure
There are at least three sheets of staples in the Staple Cartridge.
Y N
Replace the Staples.
Enter dC330 012-272 Low Staple Switch. Press Start. The display is Low.
Y N
There is less than 1 VDC from P/J1044-7 to GND.
Y N
Go to Flag 3 on BSD 12.13. Check for an open circuit. If the wire is good, Replace
the Stapler (PL 18.17).
Replace the Finisher PWB (PL 18.4).
The problem may be intermittent. Go to
the wire is good, Check for damage to the Staple Cartridge. if the problem persists, replace the
Stapler Assembly (PL 18.17).

This fault is declared if Control Logic detects more than 100 stapled sets in the Stacker Tray.
NOTE: The actual number of stapled sets allowed in the Stacker is determined by NVM loca-
tion 790-032. a value of 0 (default) allows 100 sets to accumulate before declaring the fault. A
value of 1 limits the number of sets to 60.
Initial Actions
Refer to BSD 12.15 for this procedure.
Ensure that the Stacker Tray is empty. If the fault is declared with an empty Stacker Tray, con-
tinue with this RAP.
Procedure
Enter dC330 012-253 Stacker Paper Sensor. Press Start. Manually actuate the Stacker Paper
Sensor. The display changes from Low to High to Low as the actuator moves in and out
of the sensor.
Y N
The display is always Low.
Y N
Disconnect P/J1069. There is +5 VDC from J1069-1 to J1069-3.
Y N
+5 VDC is measured from

Replace the Finisher PWB
Go to Flag 8 on BSD 12.15. Check the harness for an open circuit.
There is +5 VDC from J1069-2 to J1069-3.
Y N
Go to Flag 9 on BSD 12.15. Check the harness for an open circuit. If the wire is
good, replace the Finisher PWB
Replace the Stacker Paper Sensor
Finisher PWB (PL 18.4).
Disconnect P/J1069. The display is High.
Y N
Go to Flag 9 on BSD 12.15. Check the wire for a short circuit to GND. If the wire is
good, replace the Finisher PWB
Replace the Stacker Paper Sensor
The problem may be intermittent. Remove the Stacker Tray Bottom Cover. Check the actuator
of the Stacker Paper Sensor for damage or binding.
