Procedure
Enter dC330 [012-207] and press Start. Turn the Staple Motor Gear manually to actuate the
Staple Head Home Sensor. The display changes.
Y N
+5 VDC is measured at Stapler Assembly between P/J886-5 and P/J886-1.
Y N
+5 VDC is measured at the Finisher PWB between P/J852-1 and P/J852-5.
Y N
Replace the Finisher PWB
Check the wire between the Finisher PWB
J886 for an open circuit or poor contact.
Turn the Staple Motor Gear manually to deactuate and actuate the Staple Head Home
Sensor. The voltage changes between the Stapler P/J886-4 and Finisher Frame.
Y N
Switch off the power. Disconnect
on. +5 VDC is measured at the Finisher PWB P852-2.
