not copying from glass but ok from doc feeder. does not recognise documents size on the glass. replaced sensors under the glass and replace scanner control board and tried all pwb,s but no joy...pls help if u had this propblem ....or can shed some more light.

Is the document feeder closing properly? Does the sensor that detects the doc feed closing work properly?

Yep, what he said. It will not scan from glass if it does not think you lifted the lid to put something there.
