My prints are faded

- If the issue persists, check the life of maintenance items in case they need replacing
My prints have marks on the page
Scattered toner / stains

The Corona Wires may need cleaning, to do this follow the steps below.
- Turn off the machine.
- Take out the drum unit and toner cartridge assembly and place on a clean flat surface with a sheet of disposable paper underneath in case toner is accidentally spilt.
- Clean the primary corona wire inside the drum unit by gently sliding the green tab from left to right and right to left several times.
- Return the tab to the home position so that the ^ images match up if not the pages printed may have a vertical stripe.
- Return the cartridge to the printer, repeat for all other remaining cartridges.
- Close the printer and turn this back on. This should now be ready to use.
Marks in the same place each time
- Gently wipe the drum roller with a dry lint-free cloth.
- Print 5–6 sheets to check for improvement.

If the issue persists, print a Drum Dot Print (see your user
manual in our Helpful Links section below).
