Ring marks on an image due to the foreign substance
contamination in the developing assembly
[Symptom]
In the machines prior to the Countermeasure cut-in serial number in factory described below due to an inevitable mixing of foreign
particles, a faulty image called a ring mark may be output on the print.
[Cause]
The metal powder mixed into the developing assembly attaches onto the surface of the developing sleeve and brings a leakage
symptom to the drum. Toner attaches onto the leaked location and this leads to the aforementioned symptom.
[Service work]
When the above mentioned symptom has occurred, follow the steps below.
a) When the main unit is already installed.
1) Service mode (level 2) : COPIER>Option>IMG-DEV>ADJVPP-M/C/K, change the parameter from "-1" to "-4".
[Caution] As the ring mark has never been observed with yellow color, do not change the parameter of ADJVPP-Y from "-1".
2) Execute the auto gradation adjustment.
b) When the main unit is not installed yet.
Perform the following installation work to install the main unit.
1) Execute the service mode (level 1) : COPIER>FUNCTION>INSTALL>AINR-OFF.
2) Service mode (level 2) : COPIER>Option>IMG-DEV>ADJVPP-M/C/K, change the parameter from "-1" to "-4".
[Caution] As the ring mark has never been observed with yellow color, do not change the parameter of ADJVPP-Y from "-1".
3) Perform the works from the step 2) described in the installation procedure.
