• Code: SC505
• Description: Tandem tray rear fence motor error
  • The return sensor does not switch on within 10 sec. after the rear fence motor switches on. • The HP sensor does not switch on 10 sec. after the rear fence motor switches on. • The HP sensor and return sensor switch on at the same time.
• Causes: • Rear fence motor defective or poor connection • Paper or other obstacle interfering with operation of the sensors • Paper or other obstacle trapped between tray and motor • Motor mechanical overload due to obstruction • Return sensor or HP sensor defective or dirty

• Code: SC506
• Description: Tandem tray back fence motor error
  The back fence should be closed but the fence was not detected in the closed position within 500 ms. -or- The back fence should be open but the fence was not detected in the open within 500 ms.
• Causes: • Paper loaded incorrectly • Back fence motor harness disconnected, loose, defective • Back fence motor defective • Paper blocking sensors • Paper stuck between tray and motor • Back fence close, back fence open sensor harnesses disconnected, loose, or defective. • Back fence close, back fence open sensor defective • Paper or other obstacle is interfering with movement of the fence

• Code: SC510
• Description: LCT tray error
  • When the bottom plate is lifted, the upper limit sensor does not come on for 30 sec. • When the bottom plate is lowered, the lower limit sensor does not come on for 30 sec. • After lift begins, the upper limit sensor does not switch on before the pick-up solenoid switches on. • The paper end sensor switches on during lift and the upper limit sensor does not switch on for 2.5 s, and a message prompts user to reset paper.
• Causes: • Tray lift motor harness, disconnected, loose, or defective • Tray lift motor defective • Lift sensor defective or disconnected • Pick-up solenoid defective or disconnected • Paper end sensor defective

• Code: SC515
