008-625 REGICON SAMPLE BLOCK FAILURE
(A1 PATCH-REAR)
Description At A1 (IN) patch detection, the number of the
sample blocks does not reach the specified number.
This failure is a hidden failure. Therefore, even if a
failure occurs in the custom mode that is used by a
customer, the machine will not be aborted and the
Failure Code will not be displayed on the UI, which
means that copy output is possible.
Check Items
• After the DC956 Belt Edge Learn has completed
successfully, run DC685 Regi Control Setup Cycle to
check whether the same failure occurs.
• If the failure persists, restore the values of NVM760-7~14
and 19~26 that is related to Color Regi to defaults and run
DC685 again.
• The detection position of the MOB SENSOR 1 and 2 for
contamination, open circuit, or poor contact
• The IBT BELT and DRUM for a scratch and contamination
• The frame for distortion
• The MCU PWB, ESS PWB, and LSU (ROS) ASSY for a
failure
008-626 REGICON SAMPLE BLOCK FAILURE
(A1 PATCH-FRONT)
Description At A1 (OUT) patch detection, the number of the
sample blocks does not reach the specified number.
This failure is a hidden failure. Therefore, even if a
failure occurs in the custom mode that is used by a
customer, the machine will not be aborted and the
Failure Code will not be displayed on the UI, which
means that copy output is possible.

• The MCU PWB, ESS PWB, and LSU (ROS) ASSY for a
failure
008-627 REGICON SAMPLE LATERAL FAILURE
(A1 PATCH-REAR)
Description At A1 (IN) patch detection, the Fast Scan scan
position of CYAN color that is the standard for the rest is
incorrect. (Against the MOB SENSOR, the center position of
the CYAN pattern is shifted by ±500 µm or more. )
This failure is a hidden failure. Therefore, even if a
failure occurs in the custom mode that is used by a
customer, the machine will not be aborted and the
Failure Code will not be displayed on the UI, which
means that copy output is possible.

008-628 REGICON SAMPLE LATERAL FAILURE
(A1 PATCH-FRONT)
Description At A1 (OUT) patch detection, the scan position of
CYAN color that is the standard for the rest is incorrect.
(Against the MOB SENSOR, the center position of the CYAN
pattern is shifted by ±500 µm or more. ?
This failure is a hidden failure. Therefore, even if a
failure occurs in the custom mode that is used by a
customer, the machine will not be aborted and the
Failure Code will not be displayed on the UI, which
means that copy output is possible.

008-629 REGICON SKEW FAILURE
(A1 PATCH-Y)
Description At A1 patch detection, the relative skew
difference amount of Yellow against CYAN color exceeds the
allowable value.
This failure is a hidden failure. Therefore, even if a
failure occurs in the custom mode that is used by a
customer, the machine will not be aborted and the
Failure Code will not be displayed on the UI, which
means that copy output is possible.
