General Information
Symptom
Blanking occurs on the trailing edge of a solid-area image when there is a black frame. The problem does not
happen with the grid pattern from the copier. The width of the blanking is about 0.1 to 0.2 mm.
Leading Edge
Cause
On machines in which the relative difference between the OPC drum and the transfer belt speed is quite large,
the electrostatic absorption at the time of belt transfer causes partial shifting of the image. The difference in
the position shift of the grid pattern and the controller image is probably a result of the direct contact area
difference between the OPC drum and the transfer belt of the toner image.
Solution
1.
Adjust the tension of the transfer belt timing belt and the drum drive timing belt.
SP Adjustment: P. 1: Transfer Belt Speed Adjustment (Default: 0)
Increase the setting by +I-+2.
3.
Check the copy quality.
