SC No. Type Error Name/Error Condition/Major Cause/Solution
• 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 incorrectly" to the main
machine.
• Lift motor error/connector missing
