SC No. Type Error Name/Error Condition/Major Cause/Solution
• Lift motor error/connector missing
• Limit sensor error/connector missing
• Harness broken
• Bank control board defective
• Paper overload
• Foreign object, such as paper scrap, is caught between the paper
feed tray and the tray lift motor
• Paper set incorrectly
Remove the jammed paper or slip of paper from the tray, and check if the
SC occurs by turning the main power OFF then ON. If the SC occurs
again, do the following steps. Check if the SC reoccurs by cycling the
power after each step.
1. Check if all connectors in Tray 3 are connected securely. Reconnect
the connectors if they are disconnected, or loose.
2. Check the harness in Tray 3. Replace the harnesses if it is
disconnected, or damaged.
3. Check if the motor runs, sensors turn OFF/ON, has no overloads,
and is properly driven. Replace the parts if there are any defects.
4. Check if there are any signs of a short circuit. Replace the parts if
there are any defects.
SC503-31 B 3rd Tray Lift Error (LCIT PB3170/PB3230 (D695))
• 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 incorrectly" to
the main machine.)
