ISSUE:
E280-0004 Scanner unit (READER) communication error.
The machine will copy form ADF and if the ADF is not open then closed, it will copy from platen glass.
The error will only occur when the ADF is open then closed.
PS101 (ADF Open/Close Sensor1) and PS102 (ADF Open/Close Sensor2) were checked in Situation mode and both worked fine.
Solution:
Replacing the Scanner Ribbon cable in the Reader unit fixed the issue.
