described in “Cleaning the Fuser Rollers” on page 8–5.
• If you cannot remove all of the dirt, replace the fuser unit.

for that color (see “Replacing Toner Cartridges” on page 5–4).
• Otherwise, go to step 2.
2. Make sure that the paper loaded in the printer is free of excess moisture and
meets the specifications listed in “Choosing Paper” on page 2–2.
