Service Manual
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 coupler and drive gears for
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
deposits on the back of the paper if
toner is building up on the hot roll.
This buildup may transfer to the
backup roll, later transferring to the
back of the paper.
Inspect the hot roll and backup roller
for signs of contamination.
Replace the fuser as necessary.
A transfer roll contaminated with
toner can cause toner to transfer to
the back of printed pages.
Inspect the transfer roll for
contamination and replace as
necessary.
