Code :

Code: SC28-02
Description: A transfer leak is detected. After a transfer error detection signal is detected while in the transfer ON, up to 5 transfer ON/OFF operations occur in succession while in 10 prints.
Causes: Transfer/separation charger Power feeding point High voltage unit /2 (HV2)
Remedy: The main body stops immediately to turn OFF the RL1 (main).

Code: SC28-03
Description: A separation leak is detected. After a separation error detection signal is detected while in the separation ON, up to 5 separation ON/OFF operations occur in succession while in 10 prints.
Causes: Transfer/separation charger Power feeding point High voltage unit /2 (HV2)
Remedy: The main body stops immediately to turn OFF the RL1 (main).

Code: SC28-04
Description: The error detection signal (blowout of a 24V fuse) of the high voltage unit /2 (HV2) is detected.
Causes: ADU drive boards /1, /2 (ADUDB1, 2) High voltage unit /2 (HV2)
Remedy: The main body stops immediately to turn OFF the RL1 (main).

Code: SC29-01
Description: The dirt correction of the sensor is not completed. While in the maximum density correction, the dirt correction of the maximum density sensor is not sufficient. When this condition is detected 10 times in succession, the error code is displayed.
Causes: Toner control sensor board (TCSB)
Remedy: The main body stops immediately to turn OFF the RL1 (main).

Code: SC29-02
Description: The maximum density correction is not completed. While in the maximum density correction, the number of rotations of the developing sleeve gets to the maximum.
Causes: Toner control sensor board (TCSB) Developing motor (M3)
Remedy: Error codes are not displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. The control of the main body is made by using a data previously obtained.

Code: SC29-03
Description: The maximum density sensor output abnormality. While in the maximum density correction, a patch for control is not output. (No output is made from the maximum density sensor.)
Causes: Toner control sensor board (TCSB) Write unit Image processing board (IPB) Overall control board (OACB)
Remedy: Error codes are not displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. The control of the main body is made by using a data previously obtained.

Code: SC29-04
Description: The dirt correction of the sensor is not completed. While in gamma correction, the dirt correction of the gamma sensor is not sufficient. When the SC29-4 or SC29- 7 is detected ten times in succession, this error code is displayed.
Causes: Toner control sensor board (TCSB) (gamma sensor cleaning required)
Remedy: The main body stops immediately to turn OFF the RL1 (main).

Code: SC29-05
Description: The gamma sensor output abnormality. While in the gamma correction, a patch for control is not output. (No output is made from the gamma sensor.)
Causes: Toner control sensor board (TCSB) Write unit Image processing board (IPB) Overall control board (OACB)
Remedy: Error codes are not displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. The control of the main body is made by using a data previously obtained.
