• At the staple preparation operation at initialization, the Staple Ready Sensor does not go
to ready (L) status after 13 ready attempts.
• The Stapler Ready Sensor is turned off (H) just before the Staple.
Procedure
Remove the Stapler Assembly with a connector connected ( REP 12.11 ). Enter dC330 [012-
209] and press Start . Actuate the Staple Ready Sensor. The display changes.

Replace the Finisher PWB ( PL 17.13 ) ( Figure 3 ).
Check the wire between the Finisher PWB P/J852 -1 and the Stapler Assembly P/
J886 -5 for an open circuit or poor contact ( Figure 1 ).

Replace the Finisher PWB ( PL 17.13 ).
Check the circuit between the Finisher PWB P852 and the Stapler Assembly P/J for
obvious damage (
Figure 2 ).
If the wires are good, replace the Stapler Assembly ( PL 17.9 ).
Replace the Finisher PWB ( PL 17.13 ).
Restore the Staple Head to the original status and cheat the Front Interlock Switch.

Check resistance of the following ( Figure 2 ):
• Between the Finisher PWB P/J847 -7 and Stapler Assembly P/J887 -1
• Between the Finisher PWB P/J847 -8 and Stapler Assembly P/J887 -2
• Between the Finisher PWB P/J847 -9 and Stapler Assembly P/J887 -3
• Between the Finisher PWB P/J847 -10 and Stapler Assembly P/J887 -4
If no problems are found, replace the Stapler Assembly ( PL 17.9 ).
If the problem continues, replace the Finisher PWB ( PL 17.13 ).
