white copy in IR2200

Check whether the paper is damp or not. Also check the developer engagement system ( the engagement bar ) sometimes the plastic catch behind the bar came off causing different pressure in locking the developer. Change the composite power supply and the transfer unit.

Dev bias...or as simple as not locking the dev back into place after fitting a drum...(a trainee Tech did that with me on a call today)

Are you using an OEM Drum... I have had issues with genaric drum units for this machine...They look ok but they fail quite often. do you still have the old drum. put it back in and try it.

do you use original toner?
if not maybe you mis use with toner for ir 7200/8500.
It happens once with me.

try to clean the developing and then refill with fresh toner
