Initial issue
12-241 Staple Move Sensor On
• The Staple Sensor did not turn on after the Stapler moved to the Staple Position.
• The Staple Sensor did not actuate after the Stapler is in position.
Initial Actions
• Check for obstructions in the Stapler Unit Rail.
• Check the Rail for wear.
Procedure
Open the Front Cover Door (PL 17.5) and manually move the Stapler toward rear and front.
The Stapler moves smoothly.
YN
Repair the cause of Staple Head not moving, such as rail breakage, drag, or damaged
gear.
Enter dC330 [012-224] and press Start. Actuate the Staple Move Sensor (PL 17.9) (Figure 1)
by manually moving the Stapler toward the rear and front. The display changes.
YN
Press Stop. Check the circuit of the Staple Move Sensor (Figure 2). Refer to the OF 99-2
RAP for troubleshooting procedure.
Press Stop. Manually move the Stapler to the middle of the Rail. Cheat the Front Cover Door
Interlock Switch (PL 17.13). Enter dC330 [012-081] (front) or [012-083] (rear) and press Start.
The Staple Move Motor (PL 17.9) energizes.
YN
Press Stop. Remove the Rear Cover (PL 17.5). +24 VDC is measured between P/
J847- 3 and 4 and GND (Figure 3).
YN
Replace the Finisher PWB (PL 17.13).
+24 VDC is measured between P/J847- 1, 2, 5 and 6 and GND.
YN
Check wiring between P/J847 and P/J888 for damage or poor contact. If the check
is OK, replace the Staple Move Motor (PL 17.9).
Replace the Finisher PWB (PL 17.13).
Press Stop.
• Ensure that the connectors shown in the circuit diagrams (Figure 2, Figure 3) are securely
connected and that the wires are not damaged.
• Ensure that the Stapler Harness (PL 17.9) does not obstruct the Staple Head and that the
harness is properly secured.
• Replace the Staple Move Sensor (PL 17.9).
• If the problem persists, replace the Finisher PWB (PL 17.13) (Figure 4).
