Remedy: 1 Are the connectors CN4 at the tray elevator motor and connector PJ4 on the finisher control board properly connected? Go to step 2. Properly connect the connectors. 2 Make sure that the finisher set switch is activated. Power the printer off. Measure for approximately +24 V dc (±10%) between pins 1 and 2 of connector CN4 at the tray elevator motor. Power the printer on and observe the voltage meter during the first 12 seconds of power up. Is +24 V dc present while the printer is powering up? Replace the tray elevator motor. Go to step 3. 3 Disconnect CN4 at the tray elevator motor. Disconnect PJ4 on the finisher control board. Measure for continuity between CN4 pin 1 and PJ4 pin 7. Measure for continuity between CN4 pin 2 and PJ4 pin 8. Is there continuity in both locations? Go to step 4. Replace the cable. 4 Measure for +24 V dc (±10%) between pins 1 and 2 on connector PJ6. Is +24 V dc present? Replace the finisher control board. Replace the finisher power supply.
Description: Stapler Motor Error
Remedy: 1 Are staples jammed in the stapler? Go to step 2. Go to step 3. 2 Clear the staple jam and run the staple test in diagnostic mode or run a staple job. Does the problem reoccur? Replace the staple cartridge and to go step 4. Problem solved. 3 Are the connectors CN5 on the stapler and PJ1 on the finisher control board securely connected? Go to step 5. Securely connect the connectors. 4 Did replacement of the stapler cartridge resolve the problem? Problem resolved. Replace the stapler. 5 Make sure the finisher set switch is activated. Measure for 5 V dc between pins 11 and 12 on stapler connector CN5. Is 5 V dc present? Replace the stapler. Replace the finisher control board. 6 Did replacement of the finisher control board correct the problem? Problem solved. Go to step 7. 7 Is there continuity on the stapler to finisher control board cable? Replace the power supply. Replace the cable.
