E196 0801 05 Title EEPROM communication error
Detection Although access to the HVT EEPROM from the DC Controller
description PCB (CPU) was executed for 3 times, no response was
received and timeout occurred.
Remedy [Related parts]
- Harness between the DC Controller PCB (UN04/J110) and the
Y/M/C/Bk Laser Driver PCB (UN05/J202) (Unit of replacement:
CABLE, LASER SCANNER)
- Harness between the DC Controller PCB (UN04/J184)
and the Developing High-voltage PCB (UN06/J241) (Unit of
replacement: 2ND TRNSFR. H.V. PCB ASSEMBLY)
- Y/M/C/Bk Laser Driver PCB (UN05) (Unit of replacement:
LASER SCANNER ASSEMBLY)
- Developing High-voltage PCB (UN06) (Unit of replacement:
2ND TRNSFR. 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.
