Clean the automatic document feeder (ADF)

The ADF requires periodic cleaning depending on the amount of use and the type of paper that is fed through it. If you use the ADF several times per week, monthly cleaning is recommended. Set up a cleaning routine that is appropriate for the device.

If streaks exist on scanned documents, cleaning the ADF frame might solve the problem.
