Print quality problems

You can solve many print quality problems by replacing a supply or maintenance item that has reached the end of its

intended life. Use the following table to find solutions to print quality problems.

Dust is gathering on the

paper tray when it is

extended.

Attach the dust cover to the back of the printer. This protects the paper tray from the

environment as well as keeping the tray from being knocked out of position while it is

extended.

See Attaching the dust cover for information about attaching the dust cover.

The paper tray is getting

bumped and pushed out

the front of the printer when
