842.02 Scanner Communication Failure Error
•This error indicates a communication problem when
scanning from the Automatic Document Feeder (ADF).
•The error occurs when the ADF is trying to initiate a second
scan job when there is no second scan; it doesn’t know
how to handle the copy request so it posts the error.
•Loading custom-size media in the ADF when the size of the
media copied is different from that which is selected may
cause this error.
•Also, this error may occur when the wrong paper size value
is selected as “Copy From” compared to what is actually
being scanned in the ADF.

settings.
