Developing Screw rotation detection error (Bk)
The difference between the maximum and the minimum of sampling values detected by the Toner
Density Sensor (Bk) in the Developing Unit (Bk) was 12 V or less during rotation of the Developing
Screw.
[Related parts]
- Developing Unit (Bk)
- DC Controller PCB
- Main Drive Unit
- Harness between the Developing Unit (Bk) and the DC Controller PCB
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. Check the disconnection of the Developing Unit (Bk) Harness/Connector.
2. Remove the Developing Unit (Bk) and check if you can rotate the coupling of the Developing
Unit (Bk) by hand. If it is too heavy to rotate, replace the Developing Unit (Bk).
3. Replace the Main Drive Unit.
4. Replace the DC Controller PCB.
[Reference] Before replacing the DC Controller PCB, back up the service mode data and restore
the backup data after the replacement so the data may be able to be protected.
- Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP
- Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
Bottle Motor error (Y)
The Toner Supply Sensor (Y) did not detect change for 1.5 sec or longer while the Bottle Motor
(YM) was rotated at toner supply.
[Related parts]
- Harness between the Bottle Motor (YM) and the DC Controller PCB
- Harness between the Toner Supply Sensor (Y) (PS26) and the DC Controller PCB
- Toner Bottle (Y)
- Toner Supply Sensor (Y) (PS26)
- Bottle Drive Unit (YM)
- DC Controller PCB
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. Check if the Toner Bottle (Y) is properly inserted into the main machine.
2. Remove the Toner Bottle (Y), shake it 10 times up and down with the end (Pump Unit side)
facing upward, and then insert it into the main machine again.
3. Check the Harness/Connector among the DC Controller PCB, the Bottle Motor (YM), and the
Toner Supply Sensor (Y) (PS26).
4. Replace the Toner Supply Sensor (Y) (PS26)
5. Replace the DC Controller PCB.
6. Check the Bottle Drive Unit (YM)
7. Replace the Bottle Drive Unit (YM)
[Reference] Before replacing the DC Controller PCB, back up the service mode data and restore
the backup data after the replacement so the data may be able to be protected.
- Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP
- Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
Bottle Motor error (Y)
Rotation of bottle was detected while the Toner Bottle Motor (Y) was OFF.

[Remedy] Check/replace the related harness/cable, connector and parts.
[Reference] Before replacing the DC Controller PCB, back up the service mode data (approx. 2
min) and restore the backup data after the replacement so the data may be able to be protected.
