Cleaning the ADF Feed Roller
Keeping the ADF feed roller clean helps ensure the best possible copies. It is
recommended to clean the ADF feed roller at regular intervals.
1 Open the ADF cover.
2 Wipe the ADF feed roller with a dry soft lint-free cloth or paper towel until it
is clean.
If the ADF feed roller gets soiled with ink stains, paper from the ADF may
also be soiled. In this case, slightly dampen a soft lint-free cloth or paper
towel with a neutral detergent or water, and then remove the contamination
from the ADF feed roller until it is clean and dry.
