The Staple Ready Sensor does not detect the Staple sheet in the Ready position just prior to
stapling, or within 13 dummy staplings at Stapler initialization.
Initial Actions
Refer to BSD 12.13 for the following procedure:
• Ensure that connector P/J1092 is seated correctly to the Stapler Assembly, that connec-
tor P/J1044 is seated correctly to the Finisher PWB and that there are no obvious
crimped or broken wires on either connector.
• Ensure that the Staple Cartridge contains staples and that it is correctly installed in the
Stapler Assembly.
Procedure
Remove, then reinstall, the Staple Cartridge. Enter dC330 012-273 Staple Ready Sensor.
Press Start. The display indicates Low.
Y N
Go to Flag 7 on BSD 12.13. Check the wires for an open circuit or a short circuit to GND.
If the wires are good, go to Flag 4 on BSD 12.13. Check the wire for an open circuit. If the
wire is good, replace the Stapler Assembly
The Stapler Assembly appears to be operating correctly. If the problem continues, replace the
Staple Cartridge and test the system. If the problem continues, replace the Stapler Assembly
(PL 18.17).
