Title

Black image density sensor

trouble (Transfer belt surface

reflection ratio abnormality)

F2 44 Display Lamp/Message

Phenomenon Detail Before starting process

control, the transfer belt

surface is scanned with the

image density sensor to

adjust the sensor gain so

that the output becomes a

fixed value. However,

when the sensor gain is

changed, the output is not

within the specified range.

Section —

Common Check Use SIM 44-2 to adjust the

process control sensor

gain.

Case 1 Cause When "Error" occurs in

SIM 44-2:

1. Dirt/defect of the image

density sensor

2. Disconnection of the

harness between the

PCU PWB and the

image density sensor

3. Calibration plate

solenoid operation

trouble

Check &

Remedy

1. Clean/replace the

image density sensor.

2. Connect/replace the

harness between the

PCU PWB and the

image density sensor.

3. Replace the calibration
