Action
Banding appears as light or dark
horizontal lines on a uniformly gray
page or on a page with a large area
of graphics. Banding is primarily due
to a variation in the speed of the
paper as it feeds through the printer
especially in the developer and
transfer process. Inspect the toner
cartridge and paper feed
components, especially the drive
gears, for signs of wear, debris,
binds or damage.
Action
Inspect the overall paper path for
signs of spilled toner. Gently clean
the contaminated areas with a soft
cloth or compressed air.
The fuser hot roll can cause toner on
the back of the paper if toner is
building up on the hot roll. This
buildup may transfer to the backup
roller, later transferring to the
backside of the paper. Inspect the
hot roll and backup roller for signs of
contamination and replace as
necessary.
A transfer roller contaminated with
toner can cause toner to transfer to
backside of printed pages. Inspect
the transfer roller for contamination
and replace as necessary.
