E806 0100 05 Title Drum Unit Suction Cooling Fan error
Detection The Drum Unit Suction Cooling Fan did not rotate for the
description specified period of time since the start of drive.
Remedy [Related parts]
- Harness between the DC Controller PCB (UN04/J180) and
the Primary Transfer High-voltage PCB (UN03/J271) (Unit of
replacement: CABLE, PRIMARY TRANSFER H.V.)
- Harness between the Primary Transfer High-voltage PCB
(UN03/J272) and the Drum Unit Suction Cooling Fan (FM01)
- Drum Unit Suction Cooling Fan (FM01)
- Primary Transfer High-voltage PCB (UN03) (Unit of
replacement: 1ST TRANSFER H.V. PCB ASSEMBLY)
- DC Controller PCB (UN04) (Unit of replacement: DC
CONTROLLER PCB ASSEMBLY)
[Points to note at work] When checking the harness/cable or
connector, perform the following work.
1. Disconnect and then connect the connector to check that
there is no bent pin and cable disconnection.
2. Visually check that the harness is not caught or open circuit.
3. If there is any error, replace the corresponding harness/cable.
[Remedy] Check/replace the related 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.
