• Code: SC503-31
• Description: 3rd Tray Lift Error (LCIT) • Upper limit detection error (during descent) During tray initialization (upper limit detection/lower limit not detected), the tray base plate is lowered to check the tray base plate position, and the limit sensor is detected although a predetermined time elapsed, for 3 times consecutively. • Upper limit detection error (during ascent) During tray initialization (upper limit not detected/lower limit detection), the tray base plate is raised to check the tray base plate position, and the limit sensor is not detected although a predetermined time elapsed, for 3 times consecutively. (up to 2 times consecutively, LCIT transmits "tray set fault" to the main machine)
• Causes: • Lift motor error/connector missing • Limit sensor error/connector missing • Harness broken • Bank control board defective • Foreign matter, such as paper scrap, is caught between the right tray and the tray lift motor • Paper set fault • Timing belt damage/dropout • Timing pulley damage/dropout • Base plate damage/horizontality fault • Paper feed roller missing item • Pickup arm damage • Foreign matter, such as paper scrap, is caught inside the right tray
• Remedy: • Reset the paper • Remove the foreign matter • Replace the motor • Reset the connector • Replace the harness • Replace the sensor • Replace the control board for the optional paper feed tray • Replace the tray • Replace the paper feed roller • Replace the pick-up arm • Replace the timing belt • Replace the timing pulley • Replace the base plate

• Code: SC503-32
• Description: 3rd Tray Lowering Error (LCIT) • Lower limit detection error (during descent) During tray initialization (upper limit not detected/lower eject limit detection), the tray base plate is lowered to check the tray base plate position, and the lower limit sensor is not detected although a predetermined time elapsed. Alternatively, at paper end, the tray base plate is lowered, but the lower limit sensor is not detected although a predetermined time elapsed. • Lower limit error (during ascent) During tray initialization (upper limit eject detection/lower limit detection), the tray base plate is raised to check the tray base plate position, and the lower limit sensor is detected although a predetermined time elapsed. *If an error occurs 3 times consecutively: LCIT transmits "3rd tray lower limit detection error" to the main machine. Up to 2 times consecutively, LCIT transmits "tray set fault" to the main machine.
• Causes: • Lift motor error/connector missing • Lower limit sensor error/connector missing • Harness broken • Bank control board defective • Foreign matter, such as paper scrap, is caught between the right tray and the tray lift motor • Paper set fault • Timing belt damage/dropout • Timing pulley damage/dropout • Base plate damage/horizontality fault • Foreign matter, such as paper scrap, is caught inside the right tray
