I look after a Xero WorkCentre 7535 and it is going great but after a recent glass screen (removing black marks on glass) on the copier the machine is now selecting A3 paper as the default paper when copying from flatbed. I have taken a look through the web settings but can't find any settings that control this and I doubt that cleaning the glass would have caused a problem.
Does anyone have any idea on what I can do to fix this problem?
The White backing on the ADF when you open it , either that has something on it that the printer picks up as the paper edge, or someone doing an unrelated thing, changed the default original size.
So check the white matt on the lid, and if nothing, change back the defaults.
To do so, at the copier log on as admin and go to Machine Status > Tools > Service Settings > Copy Service > Feature Defaults > Layout/Adjustment > Original Size > Auto Detect > Save > Save defaults
