Details
(1) Symptom at occurrence of alarm
Since toner supply amount for the image
density to be printed is not enough, light
density, error due to light density or image
failure occurs.
However, the foregoing error occurs
simultaneously with the errors caused by light
density (E020-0xB1, E020-0x91, E020-0x60).
x= 0: Y, 1: M, 2: C, 3: Bk
(2) Factor causing alarm
Due to control of toner supply amount per
image, toner consumption becomes larger than
toner supply when printing of a large quantity
of extremely high density images continues,
so that TD ratio in the Developing Assembly
decreases, causing the occurrence of the
alarm.
(3) Support by service technician
- Print approx. 20 sheets of A3 halftone image
with the color with which the alarm occurred.
As long as not continuously printing a large
quantity of high density images, TD ratio in the
Developing Assembly recovers while keeping
print operation. However, this alarm (and error)
repeatedly occurs while continuing to print high
density images.
As the permanent measure, it is necessary to
reduce the image print density or put low to
medium density image printings between high
density image printings as needed.

Details
Error in the Primary Transfer High Voltage
PCB, Error in the Primary Transfer Roller (ITB
Unit)
1. Check failure of the harness between the
Primary Transfer High Voltage PCB (UN04/
J1001) and the DC Controller PCB (UN09/
J205) (open circuit, trapped cable, connector
disconnection).
-> Replace the harness if it is faulty
2. Check connection failure between the
Primary Transfer High Voltage PCB (UN04/
J31) and the Primary Transfer Roller (Check
that the connection is free from open circuit or
GND contact)
3. Replace the Primary Transfer High Voltage
PCB (UN04)
4. Replace the ITB Unit
5. Replace the DC Controller PCB (UN09).
6. Replace the Primary Transfer Power Supply
Unit
Error detection of the Drum Unit cooling fan
Due to misalignment in reading data as a result
of misdetection that soil or scar on the belt was
detected as pattern
Due to misalignment in reading data as a result
of misdetection that soil or scar on the belt is
detected as pattern
Color displacement is not properly corrected as
a result of the drum phase control.
Possibly an error in the Drum Phase Sensor
- Cause: Minor soiling occurred to the Polygon
Mirror in the Laser Scanner.
- Detection timing:
(1) When executing D-half control
(2) When executing auto gradation adjustment
- Remedy: While no immediate remedy is
necessary, replace the Laser Scanner Unit if
34-3001 occurs.
- Cause: Heavy soiling occurred to the Polygon
Mirror in the Laser Scanner.
There is a high possibility of resulting in E020-
1x60 at the replacement of drum.
- Detection timing:
(1) When executing D-half control
(2) When executing auto gradation adjustment
- Remedy: Replace the Laser Scanner Unit.
