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.
Causes: Upper limit sensor (PS2) Lift-up motor (M1)
Remedy: 1 Check the M1 connector for proper connection and correct as necessary. 2 Check the connector of M1 for proper drive coupling and correct as necessary. 3 PS2 I/O check, sensor check LUDB CN5-3 (ON) LU-204 G-4 4 M1 operation check LUDB CN3-4 (ON) LU-204 G-3 5 Change M1 6 LUDB ICP2 conduction check 7 Change LUDB
Code: C0301
Description: Suction fan motor’s failure to turn • The fan lock signal remains HIGH for a predetermined continuous period of time while the motor remains stationary.
Causes: Suction fan motor (FM1) Paper feed/transport drive board (PFTDB)
Remedy: 1 Check the FM1 connector for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM1 operation check PFTDB CN5-3 (REM) PFTDB CN5-5 (LOCK) Q-6 4 Change FM1 5 PFTDB ICP2 conduction check 6 Change PFTDB
Code: C0351
Description: Paper cooling fan trouble • The fan lock signal remains HIGH for a predetermined continuous period of time while the motor remains stationary.
Causes: Paper cooling fan motor (FM13) Printer control board (PRCB)
Remedy: 1 Check the FM13 connector for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM13 operation check PRCB CN15-7 (REM) PRCB CN15-9 (LOCK) K-9 4 Change FM13 5 PRCB ICP6 conduction check 6 Change PRCB
Code: C1003
Description: PK communication error <When FS-526+PK-516 is installed> • When a communication error is detected between the FS control board (FSCB) and the punch control board (PKDB).
Causes: Punch control board (PKDB) FS control board (FSCB)
Remedy: 1 Disconnect and then connect the power cord. Turn OFF the main power switch, wait for 10 sec. or more, and turn ON the main power switch. 2 Rewrite the firmware. 3 Change PKDB 4 Change FSCB
Code: C1004
