SC505-42 B Side LCIT Lower Limit Detection Error
§ Lower limit detection error (during descent)
During tray initialization (upper limit not detected /lower limit
eject detection), the tray base plate is lowered to check the
tray base plate position, but 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 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, but the lower limit sensor is detected
although a predetermined time elapsed.
*If an error occurs for 3 times consecutively: the side LCIT
transmits a "5th paper feed tray upper limit detection error"
to the main machine.
Up to 2 times consecutively, the side LCIT transmits a "tray
set fault" to the main machine.
§ Lift motor error/connector missing
§ Lower limit sensor error/connector missing
§ Harness broken
§ Bank control board defective
§ 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
tray
