How can entered serial number to be Konica Minolta c 452. Pleas answer. I am waiting for your MG's.

Main Board for the copier that receive info from the Document feeder is causing that code. Is your machine DS version or none version? Could have the incorrect document feeder for that machine, or the small printed circuit board that come with document feeder is bad. Could try a different document feeder. Might also see if you can have tech come and re-flash the copiers firmware specially the document feeder and or the MFB Board (Multi Function board) is bad.

Try pull up error

Are you sure it is asking for a serial number, or is it a password and or pin code. Machine will not ask for a serial number. Never in ten years have I seen that
