Initial issue
Status Indicator RAPs
12-960 Stacker Tray Full Stack
• The system detected small size paper full during the Stacker Tray Height Adjustment
operation during lowering.
• The system detected small size paper full during the Stacker Tray Height Adjustment
operation (during lowering down) when the large size paper is ejected.
• The large size paper was ejected while the system already detected large size paper full
(half).
Procedure
Remove the Finisher Front Cover. Enter dC330 [012-204] and press Start. Actuate the Stack A
Sensor (Figure 1). The display changes.
YN
Press Stop. Check the circuit of the Stack A Sensor (Figure 2). Refer to the OF 99-2 RAP
for troubleshooting procedure.
Press Stop. Enter dC330 [012-205] and press Start. Actuate the Stack B Sensor. The dis-
play changes.
YN
Press Stop. Check the circuit of the Stack B Sensor (Figure 3). Refer to the OF 99-2 RAP
for troubleshooting procedure.
Enter dC330 [012-200] and press Start. Actuate the Stacker Paper Sensor. The display
changes.
YN
Press Stop. Check the circuit of the Stacker Paper Sensor (Figure 4). Refer to the OF 99-
2 RAP for troubleshooting procedure.
Press Stop. Rotate the Stacker Motor Drive Pulley manually by turning the Stacker Drive
Motor Drive Gear (PL 17.11). The pulley rotates smoothly.
YN
Check the following and repair the Stacker Drives as required (PL 17.11).
• Stacker Motor Gear for wear and damage.
• Stacker Tray for dragging and incorrect installation.
• Stacker Elevator Belt/rack/gear for wear and damage.
Disconnect Stacker Motor P/J889. Measure the resistance between pin 1 and pin 2 of the
motor connector. Between 12 to 40 ohms is measured while the pulley is rotated manu-
ally.
YN
Replace the Stacker Motor (PL 17.11).
• Ensure that the connectors shown in the circuit diagrams (Figure 2, Figure 3, Figure 4,
Figure 5) are securely connected and that the wires are not damaged.
• If the problem persists, replace Finisher PWB (PL 17.13) (Figure 6).
NOTE: The large white Stacker Drive Pulley can be pulled out to release the Stacker Drives to
free the Stacker Tray (REP 12.20).
