No toner detection error (Bk)
- The state without toner was detected although the recovery sequence was performed for 5 times
after replacement of the Toner Container (Bk).
- The recovery sequence was repeated with no toner in the container.
[Related parts]
- Toner Container (Bk)
- Bottle Drive Unit (CK) (Unit of replacement: BOTTLE DRIVE ASSEMBLY, C, K)
- Developing Unit (Bk) (UN24) (Unit of replacement: DEVELOPING ASSEMBLY, BK)
- ITB Rail Rear Unit (Unit of replacement: I.T.B. RAIL ASSEMBLY, REAR)
[Remedy] Be sure to perform the following procedure.
1. Shake the Toner Container 10 times, and then insert it into the host machine.
2. Check/replace the related harness/cable, connector and parts.
Registration Patch Sensor (Front) density error
The background regular reflection output of the Registration Patch Sensor Unit (Front) did not fall
within the range from 115 to 1000 at initialization of the Developing Unit.
[Related parts]
- Harnesses from the Registration Patch Sensor Unit (Front) to the DC Controller PCB
1. Registration Patch Sensor Unit (Front) (UN26/J1022) to Relay Connector (16P) (Unit of
replacement: REGISTRATION SENSOR ASSEMBLY)
2. Relay Connector (16P) to DC Controller PCB (UN04/J120) (Unit of replacement: NEW OLD
SENSING HOLDER UNIT)
- Registration Patch Sensor Unit (Front) (Unit of replacement: REGISTRATION SENSOR
ASSEMBLY)
- DC Controller PCB (Unit of replacement: DC CONTROLLER PCB ASSEMBLY)
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. Check if the sensor window of the Registration Patch Sensor Unit (Front) is soiled. If it is soiled,
clean it with lint-free paper moistened with water.
2. 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.
