Action
Remove the problem print cartridge and shake it
gently to distribute the toner evenly. The
cartridge may also be low on toner and may
need replacing.
Try a new ITM unit.
Check the transfer roll for signs of
contamination, such as adhesives or toner
buildup.
Check for surface damage to the roll, replacing
the roll if necessary.
Action
Gently shake the toner cartridges to evenly
distribute the toner. If lines or bands remain, one
of the cartridges may have a scratch on the
photoconductor.
Run the "Print Quality Test Pages" on
page 3-1, to isolate the failing cartridge. If a
particular cartridge is found to produce the line
or band at the same spot as on the printed
page, replace the failing cartridge.
Remove the ITM from the printer and carefully
examine the belt for marks or scratches at the
same spot as on the printed page.
Examine the transfer roll for signs of damage or
contamination which might cause a line or band
to occur at the same location as on the printed
copy.
