Problem Sample Cause Solution
Partial missing color plane (faded
print).
One or more color planes are
missing toner. The area between
where the toner appears and
disappears is a wavy pattern.
The transfer roller in the ITB
does not have even pressure
across the belt due to a broken
bushing, or the ITB transfer
roller is partially alienated.
Remove the ITB, and then check the
black or white bushings on the ends of
the transfer rollers for damage. The
bushings should all be in place and
spring-loaded. If the ITB is damaged,
replace it.
Missing trailing edge of document
feeder (ADF) scans (M680).
The image in the print job is
skewed.
Make sure that the image is properly
placed on the page before the job is
copied.
The copy image might be
getting stopped early due to
static interfering with the ADF
paper path deskew sensor in
the ADF.
NOTE: The page does not jam,
but is skewed when printed.
Replace the document feeder.
