Type Error Name/Error Condition/Major Cause/Solution
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 the side LCIT are connected securely.
Reconnect the connectors if they are disconnected, or loose.
2. Check the harness in the side LCIT. 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.
B Side LCIT Lower Limit Detection Error (LCIT RT3030 (D696))
• 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
incorrectly" to the main machine.
