4. Toner leakage (Bk)
No toner is applied on the rear side of sleeve cylinder.
The front side of machine is soiled with toner including carrier. If the soiling gets worse, the front side of paper is soiled.

Need to replace the developing assembly
Clean inside the machine
Perform service work
Clean inside the machine.
Is the developing assembly heavier than the service part (new) developing assembly?
Same or lighter.
Wait and see
Yes
After shaking the developing assembly gently, execute STIR Bk inside the machine. As the result, the assembly lose weight.
Output 200 pages of PG 10 images.
Service work: Workflow
* Faulty images due to high voltage error are output
Images with solid area even in margins or images with toner (rough texture)
throughout the page is output.
*Replace the 1st transfer H.V. PCB ass’y (FM3-9590).
As the measure against the temperature rise inside the machine, place the machine far away from the wall as much as possible, and replace the 3 filters regularly.
- Distance between the rear side of machine and the wall: preferably 10cm or more
- Filter (3 filters) replacement intervals: every 500K images
B. Upgrade Dcon
Upgrade Dcon to ver59.01 or later. (The settings described in C in the next page take effect properly only with Dcon ver59.01 or later.)
*Output PG 10 images and replace the developing assembly at the same time. The symptom is not solved simply by replacing the 1st transfer H.V. PCB ass’y.
*PG10 image: Test image reproduced by
all the 4 colors (YMCK).
YES
NO
Does the symptom solved by outputting 200 pages of PG 10 images?

C. Change service mode settings
- Increase the developing assembly
- Change the TD ratio limiter table: Level 2 > Copier > Adjust > DENS > LLMT-PT > from “0” to “1” (Affected color only).
- Increase toner discharge amount at time of low duty job: Level 2 > Copier > Option > IMG-DEV > DEVL-VTH > from “1” to “2.”
* Pay attention to the waste toner bottle replacement intervals
* If possible, turn off the environment heater (smeared image or deterioration of hue change may occur.)
Output 25 pages of CA1 chart and then let the machine execute the post rotation. Repeat this cycle 4 times.
Notes:
1. If the value of service mode item “SIGG” has been changed, replace the developing assembly of the affected
color, and then perform the initialization on the new developing assembly. This will reset the value of “SIGG”
to the default and the new service mode settings described in “C” above take effect properly.
Level1>COPIER>ADJUST>DENS>SIGG-X
2. If the main power switch is turned off immediately after a large number of pages are output, the temperature
overshoot occurs, and consequently leading to the temperature rise inside the machine.
Relation between LLMT-PT value and T/D ratio control range
Execute the auto gradation correction
(full correction).

failure or developer leakage are explained below.
If developer remains unmoving in the front/A-B front side, developer leakage at the front or developer leakage due to
increased amount of toner may occurs.
If developer remains unmoving in the rear (D) side, excess developer is discharged, and the amount of toner inside
the developing assembly may decrease.

4.White band
5. White lines
[Causes]
A. Mixture of foreign material into the developing
temperature environment
B. Temperature rise inside the machine
When a large number of originals with a low density is printed, toner [1] is not consumed and turns
into agglomeration [4] in a space between the developing sleeve [2] and the blade [3], consequently
causing coating failure [5] on the sleeve.
C. Error in servicing
At the time of replacing the developing assembly, the initialization is performed.
But, a used developing assembly is used for this work.

iRADVC7000/9000s
6. White spots (Y,M,C)
[Symptom]
In case of less color jobs, white
[Cause]
When there are less color jobs, the toner supply control of the color developing assembly does not operate as expected resulting in toner supply shortage.
