Disconnect the power cord from the rear of the printer.
Open the ADF cover.
Find the paper pick rollers and the separator pad inside the ADF.
Lightly dampen a clean, lint-free cloth with filtered or distilled water, and then squeeze any excess liquid from the cloth.
Use the damp cloth to clean the paper pick rollers and the separator pad.
Leave the ADF cover open for two minutes to allow the rollers and pad to dry.
Close the ADF cover.
Reconnect the power cord to the printer, and then turn on the printer.
Slide in the paper width guides until they rest against the sides of the paper.
Try to scan or copy with the ADF.
