Description: LCT up/down abnormality The upper limit sensor (PS2) is not blocked even after the set period of time has elapsed after the paper lift-up operation began.
Remedy: When LU-204 is installed: 1 Check the connector between M1-LCDB CN3 for proper connection, and correct as necessary. 2 Check the connector of M1 for proper drive coupling and correct as necessary. 3 Check the connectors between PS2-relay CN406- LCDB CN5 for proper connection, and correct as necessary. 4 PS2 I/O check, sensor check LUDB CN5-3 (ON) LU-204 4-G. 5 M1 operation check LUDB CN3-4 (ON) LU-204 3-G. 6 Replace M1. 7 LUDB ICP2 conduction check. 8 Replace LUDB. When LU-301 is installed: 1 Check the connector between M1-LCDB CN3 for proper connection, and correct as necessary. 2 Check the connector of M1 for proper drive coupling and correct as necessary. 3 Check the connectors between PS2-relay CN3-LCDB CN5 for proper connection, and correct as necessary. 4 PS2 I/O check, sensor check LUDB CN5-3 (ON) LU-301 4-G. 5 M1 operation check LUDB CN3-4 (ON) LU-301 3-G. 6 Replace M1. 7 LUDB ICP2 conduction check. 8 Replace LUDB.
