Description: Tray 4 feeder up/down abnormality. The tray 4 upper limit sensor is not blocked even after the lapse of a given period of time after the lifting motion has been started.
Causes: • Tray 4 upper limit sensor (PS27) • Tray 4 lift-up motor (M24) • Paper feed/transport drive board (PFTDB) • Printer control board (PRCB)
Remedy: 1 Check the connector between M24-PFTDB CN18 for proper connection and correct as necessary. 2 Check the connector of M24 for proper drive coupling and correct as necessary. 3 Check the connector between PS27-relay CN194-relay CN121B-PFTDB CN22 for proper connection and correct as necessary. 4 PS27 I/O check, sensor check PFTDB CN22-6 (ON) 8-X 5 M24 operation check PFTDB CN18-1 to 2 9-X 6 Replace M24 7 PFTDB ICP8 conduction check 8 Replace PFTDB 9 Replace PRCB
Code: C0216
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) • LU drive board (LUDB)
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
Code: C0301
Description: Suction fan’s failure to turn The fan lock signal remains HIGH for a predetermined continuous period of time while the fan is turning.
Causes: • Suction fan (FM1) • Paper feed/transport drive board (PFTDB)
Remedy: 1 Check the connector between FM1-relay CN278-relay CN271B-PFTDB CN10 for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM1 operation check PFTDB CN10-3 (REM) PFTDB CN10-5 (LOCK) 5-P 4 Replace FM1 5 PFTDB ICP2 conduction check 6 Replace PFTDB
Code: C0351
Description: Paper cooling fan/in’s failure to turn The fan lock signal remains HIGH for a predetermined continuous period of time while the fan is turning.
Causes: • Paper cooling fan/in (FM13) • Printer control board (PRCB)
Remedy: 1 Check the connector between FM13-relay CN325- PRCB CN1 for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM13 operation check PRCB CN1-11 (LOCK) 7-K 4 Replace FM13 5 Replace PRCB
Code: C1003
Description: PK communication error <When FS-535+PK-521 is installed> When a communication error is detected between the FS control board (FSCB) and the punch control board (PKCB).
Causes: • Punch control board (PKCB) • FS control board (FSCB)
Remedy: 1 Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2 Rewrite the firmware. 3 Replace PKCB 4 Replace FSCB
Code: C1004
Description: FNS communication error When the FS control board (FSCB) is receiving data, a communication error is detected.
Causes: FS control board (FSCB)
Remedy: 1 Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2 Rewrite the firmware. 3 Replace FSCB (FS-534/FS-535)
