ï At the staple preparation operation at initialization, the Staple Ready Sensor does not go
to ready (L) status after 13 times of stapling operation.
ï The Stapler Ready Sensor is turned off (H) just before the Staple.
Procedure
Remove the Stapler Assembly with a connector connected. Enter dC330 [012-209] and press
Start. Actuate the Staple Ready Sensor. The display changes.
YN
+5 VDC is measured between the Stapler Assembly p/j (+) and Finisher PWB Chas-
sis (-).
YN
+5 VDC is measured between the Finisher PWB p/j (+) and Finisher PWB Chas-
sis (-).
YN
Replace the Finisher PWB (PL 17.13).
Check the wire between the Finisher PWB p/j and the Stapler Assembly p/j for an
open circuit or poor contact.
Pull out the cartridge. +5 VDC is measured between the Finisher PWB p/j (+) and Fin-
isher PWB Chassis (-).
YN
Switch off the power.
Pull out the on the Finisher PWB.
Turn on the power. +5 VDC is measured between the Finisher PWB P852-3 (+)
and Finisher PWB Chassis (-).
YN
Replace the Finisher PWB (PL 17.13).
Check the circuit between the p/j and the Stapler Assembly p/j for short circuit.
Load the cartridge. 0 VDC is measured between the Finisher PWB p/j (+) and Fin-
isher PWB Chassis (-).
YN
0 VDC is measured between the Stapler Assembly p/j (+) and Finisher PWB
Chassis (-).
YN
Replace the Stapler Assembly (PL 17.9).
Check the wire between the Stapler Assembly p/j and the Finisher PWB p/j for an
open circuit or poor contact.
Replace the Finisher PWB (PL 17.13).
Restore the Staple Head to the original status and cheat the Front Interlock Switch.
Enter dC330 [012-020] and press Start. The STAPLE MOTOR energizes.
YN
With [12-020] running +24 VDC is measured between the Finisher PWB p/j (+) and
Finisher PWB Chassis (-).
YN
Replace the Finisher PWB (PL 17.13).
Check conductivity of the following:
ï Between the Finisher PWB p/j ~ Stapler Assembly p/j
ï Between the Finisher PWB p/j ~ Stapler Assembly p/j
ï Between the Finisher PWB p/j ~ Stapler Assembly p/j
ï Between the Finisher PWB p/j ~ Stapler Assembly p/j
If no problems are found, replace the Stapler Assembly (PL 17.9).
If the problem continues, replace the Finisher PWB (PL 17.13).
Switch off the power.
Remove the Stapler Assembly from the Finisher.
Turn the Staple Motor Gear manually. The staple needles fed.
YN
Replace the Stapler Assembly (PL 17.9).
Replace the Finisher PWB (PL 17.13).
