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.
