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.
YN
Replace the Staples.
Enter dC330 012-272 Low Staple Switch. Press Star
t. The display is Low.
YN
There is less than 1 VDC from P
/J1044
-7 to GND.
YN
Go to Fl
ag 3 on BS
D 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).
Th
e problem may be intermittent. Go to Flag
3 on BSD 12.13. Check for a loose connection. If
the wire is good, Check for damage to the Staple Cartridge. if the problem persists, replace the
Stapler Assembly (PL 18.17).
12-531 RAP
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 St
acker 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 t
he sensor.
YN
The display is always Low.
YN
Disconnect P/
J1069. T
here is +5 VDC from J1069-1 to J1069-3.
YN
+5 VDC is measured from P
/J1038
-1 to P/J1038-3.
YN
+5 VDC is measured from P
/J1026
-3 to P/J1026-2.
YN
Go to F
lag 17 on BSD 12.1. Check the +5VDC wiring for an open cir-
cuit
.
Replace the Finisher PWB (PL 18.4).
Go
to Flag 8 on BS
D 12.15. Check the harness for an open circuit.
There is +5 VDC from J1069-2 to J1069-3.
YN
Go to Fl
ag 9 on BS
D 12.15. Check the harness for an open circuit. If the wire is
good, replace the Finisher PWB (PL 18.4)
Replace the Stacker Paper Sensor (PL 18.27).
If the problem continues, replace the
Finisher PWB (PL 18.4).
Disconnect P/J1069. Th
e display is High.
YN
Go to F
lag 9 on BSD 12.15. Check the wire for a short circuit to GND. If the wire is
good, replac
e the Finisher PWB (PL 18.4)
Replace the Stacker Paper Sensor (PL 18.27
).
The problem may be intermittent. Remove the Stacker Tray Bottom Cover. Check the actuator
of the
Stacker Paper Sensor for damage or binding.
