BULLETIN NUMBER: AFICIO COLOR 5106/5206 - 015 12/22/97
APPLICABLE MODEL: AFICIO COLOR 5106/5206
SUBJECT: BLANKING ON TRAILING EDGE
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.
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 direct contact
area difference between the OPC drum and the belt of the toner image.
SOLUTION:
1. Adjust the tension of the Transfer Belt timing and the drum drive timing belt.
2. SP Adjustment: P. 1: Transfer Belt Speed Adjustment (Default: 0). Increase the setting by +1~+2.
3. Check the copy quality.
