Description: Scanner sequence trouble 1
The original transport interval becomes shorter than the predetermined value due to an original transport control error in original reading in DF.
Remedy: 1 Correct the harness connection between main body and DF if faulty. 2 Replace DFCB (DF-624/DF-701). 3 Replace MFPB.
Code: C8101
Description: Before reading pressure welding alienation mechanism
<When DF-624 is installed> • During a pressure motion being performed, the document reading sensor (PS4) output does not change from H to L. • During a retraction motion being performed, the document reading sensor (PS4) output does not change from L to H.
<When DF-701 is installed> • During a pressure motion being performed, the document reading sensor (PS6) output does not change from H to L. • During a retraction motion being performed, the document reading sensor (PS6) output does not change from L to H.

When DF-701 is installed: 1 Check the connector between M4-DFCB J18 for proper connection and correct as necessary. 2 Check the connector of M4 for proper drive coupling, and correct as necessary. 3 Check the connector between PS6-DFCB J10 for proper connection and correct as necessary. 4 PS6 I/O check, sensor check DFCB J10-3 (ON) DF-701 2-G. 5 M4 operation check DFCB J18-4 to 5 DF-701 1-G. 6 Replace M4. 7 FSCB F8 conduction check. 8 Replace DFCB.
Code: C8107
Description: Glass cleaning mechanism trouble
<When DF-624 is installed> The document reading glass cleaning sensor (PS12) is not turned ON after the set period of time has elapsed after the glass cleaning motor (M4) is turned ON.
<When DF-701 is installed> The document reading glass cleaning sensor (PS13) is not turned ON after the set period of time has elapsed after the document reading glass cleaning motor (M6) is turned ON.
Remedy: When DF-624 is installed: 1 Check the connector between M4-DFCB J8 for proper connection and correct as necessary. 2 Check the connector of M4 for proper drive coupling, and correct as necessary. 3 Check the connector between PS12-DFCB J15 for proper connection and correct as necessary. 4 PS12 I/O check, sensor check DFCB J15-5 (ON) DF-624 3-G. 5 M4 operation check DFCB J8-1 to 4 DF-624 1 to 2-B. 6 Replace M4. 7 Replace DFCB.
When DF-701 is installed: 1 Check the connector between M6-DFCB J8 for proper connection and correct as necessary. 2 Check the connector of M6 for proper drive coupling, and correct as necessary. 3 Check the connector between PS13-DFCB J15 for proper connection and correct as necessary. 4 PS13 I/O check, sensor check DFCB J15-5 (ON) DF-701 3-G. 5 M6 operation check DFCB J8-1 to 4 DF-701 1-B. 6 Replace M6. 7 Replace DFCB.
Code: C8302
Description: Cooling fan trouble
<When DF-624 is installed> <When DF-701 is installed> • The lock signal continues to detect H during a given time while the DF cooling fan motor (FM1) is spinning. • The lock signal continues to detect L during a given time while the cooling fan (FM1) is during halts.
Remedy: When DF-624 is installed: 1 Check the connector between FM1-DFCB J16 for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM1 operation check DFCB J16-3 (ON) DF-624 3-B 4 Replace FM1. 5 DFCB F6 conduction check. 6 Replace DFCB.
When DF-701 is installed: 1 Check the connector between FM1-DFCB J16 for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM1 operation check DFCB J16-3 (ON) DF-701 7-G. 4 Replace FM1. 5 DFCB F6 conduction check. 6 Replace DFCB.
Code: C9401
Description: Exposure LED lighting failure
The output from the CCD sensor is a predetermined value or less during CCD sensor gain adjustment.
Remedy: 1 Check the connection between SCDB-LU201, and correct if necessary. 2 Check the connector between SCDB PJ1-PRCB CN43 for proper connection and correct as necessary. 3 Check the connector between CCDB PJ3-MFPB PJ01 for proper connection and correct as necessary. 4 Replace the LED exposure unit. 5 Replace CCDB. 6 Replace SCDB. 7 Replace PRCB. 8 Replace MFPB.
Code: C9402
Description: Exposure LED lighting abnormally
The average output value of the CCD sensor with the scanner at its standby position is a predetermined value or more at the end of a scan job.
Remedy: 1 Check the connection between SCDB-LU201, and correct if necessary. 2 Check the connector between SCDB PJ1-PRCB CN43 for proper connection and correct as necessary. 3 Check the connector between CCDB PJ3-MFPB PJ01 for proper connection and correct as necessary. 4 Replace the LED exposure unit. 5 Replace CCDB. 6 Replace SCDB. 7 Replace PRCB. 8 Replace MFPB.
