089-600 RC Sample Lateral Fail-A1
BSD-ON:CH6.16, CH9.18
There is an error with the Cyan fast scan position that is used as a reference during A1 (fine adjustment
pattern) and C patch detection. This is a hidden failure. The Color Regi Spec cannot be guaranteed and
Data is only recorded in history.)
NOTE: When multiple failures with Chain No. 089 (RegiCon) occur, take action according to the priority
order in the following table. Solving a higher priority failure may sometimes also repair the other failures.
(089-600 ~ 089-616 is detected when performing Regi Control, 089-617 is detected when a print instruc-
tion is issued, while 089-618 to 089-620 are detected when performing the MOB Sensor LED light
amount correction.)
Priority Chain Link
1 (High) 089-616
2 089-604 ~ 089-615
3 089-601, 089-602, 089-603
4 089-600
5 089-617
6 (Low) 089-618, 089-619, 089-620
Initial Actions
• Check whether an IBT Drive Control related Fail (042-324, 042-326, 042-327, 042-600) has
occurred. If it has, go to Step 1.
• Check whether partial poor image quality (such as low density, roller marks, dark background, con-
tamination, IBT Belt scratches, Magnet Roll scratches, and etc.) has occurred at the MOB Sensor
detection area. If it has, go to Step 2.
Procedure
- Step 1 -
Has an IBT Drive Control related Fail occurred?
Y N
Is the IBT Belt installed properly?
Y N
Install the IBT Belt properly. After the installation, perform DC675 Registration Control Setup
Cycle.
Replace the IBT Belt (PL 6.3). After the replacement, perform DC675 Registration Control Setup
Cycle.
Go to the appropriate FIPAfter the process has completed, perform DC675 Registration Control Setup
Cycle.

MOB LED Fail
Turn OFF the power and insert a sheet of blank paper between the MOB Sensor and the IBT Belt. Turn
ON the power and perform the following MOB Sensor Diag.
• MOB Sensor In: DC140 [089-200] (MOB Moni In A)
• MOB Sensor Center: DC140 [089-201] (MOB Moni Center A)
• MOB Sensor Out: DC140 [089-202] (MOB Moni Out A)
Is the analog monitor value 93 or lower for all?
Y N
Press the Stop button. Refer to the BSD and check the applicable Sensor for operation failure
(including wiring failure).
If no problem is found, replace the following parts in sequence:After the replacement, perform
DC675 Registration Control Setup Cycle.
• MOB ADC Assembly (PL 18.3)
• MCU PWB (PL 18.2)
Press the Stop button. Turn ON DC330 [092-004] (ADC Shutter Open) and DC330 [092-005] (ADC Shut-
ter Close) alternately. Is the ADC Shutter operating properly?
Y N
Go to 092-649 (ADC Shutter Open Fail) FIP or 092-650 (ADC Shutter Close Fail) FIP.
Press the Stop button and turn OFF the power. Remove each Drum Cartridge and the IBT Unit and rein-
stall them.
Turn ON the power and perform DC675 Registration Control - Setup Cycle.
If the problem persists, replace the MCU PWB (PL 18.2). After the replacement, perform DC675 Regis-
tration Control Setup Cycle.
