Corrective Action
On the General Settings tab, check that the
Lighten/Darken scroll is set to a lighten setting.
If lines or streaks are present, check the IBT
Cleaner Assembly for wear or damage, and
replace as required.
If spots or bands occur every 126mm on the
prints, the Yellow, Magenta, or Cyan Drum is
damaged or light-shocked.
If spots or bands occur every 188mm, the Black
Drum is damaged or light-shocked.
If the defect occurs every 36mm on the prints,
do not replace the Drum. This interval is caused
by a damaged or defective Developer Housing.
If lines, streaks, or deletions in the process
direction appear only with Black, then replace
the Black Scorotron Assembly.
Access the Sharpness/Color Saturation screen
by selecting the Image Quality tab.
Check that the Sharpness scroll is set to a
softer setting.
If you are copying your original from the
Document Glass, access the Original Size
screen by selecting the Original Size button on
