Status Indicator RAPs Initial issue
12-244 Staple Home Sensor
The Staple Head Home Sensor did not actuate after the Stapler Motor energized to open the
Stapler.
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 ( PL 17.13 ) ( Figure 4 ).
Check the wire between the Finisher PWB P/J852 and the Stapler Assembly P/
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 P/J852 on the Finisher PWB. Switch the power
on. +5 VDC is measured at the Finisher PWB P852-2.
Y N
Replace the Finisher PWB ( PL 17.13 ).
Check the wires between the Finisher P/J852 and the Stapler Assembly P/J886 for
obvious damage ( Figure 2 ).
If the wires are good, replace the Stapler Assembly ( PL 17.9 ).
Replace the Finisher PWB ( PL 17.13 ).
Position paper in stapler ( Figure 1 ). Enter dC330 [012-020] and press Start . The Staple
Motor ( PL 17.9 ) energizes ( Figure 3 ).
Y N
With [012-020] running, +24 VDC is measured at the Finisher PWB
P/J847 -7.
Y N
Replace the Finisher PWB ( PL 17.13 ).
Check continuity between:
•
The Finisher PWB P/J847 -7 and Stapler Assembly P/J887 -1
• The Finisher PWB P/J847 -8 and Stapler Assembly P/J887 -2
• The Finisher PWB P/J847 -9 and Stapler Assembly P/J887 -3
• 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 ).
Replace the Finisher PWB ( PL 17.13 ).
