Regularly Spaced Marks
This is caused by a defect on one of the rolls or gears in the print
process. The damaged part can be determined by the spacing of the
marks according to the following table. Find and replace the
damaged part.
Spacings other than the ones listed could be caused by damage or a
bind in the gear train.
Residual Image
Residual image--the “walking” of a leftover image down the page--is
probably the result of failed erase lamps not discharging the
photoconductor, or of a failed cleaner inside the print cartridge. It
can also be caused by a failed fuser hot roll retaining toner and
redepositing it on the page. Check that the erase lamp voltage at
(10P) J20-1 (10R/12R/12C/12L) J20-16 (16L) J17-16 is +24VDC
and that the cable has continuity.
To test the erase lamps, jumper (10P) J20-2 (10R/12R/12C/12L)
J20-15 (16L) J17-15 to ground.
