My Konica Minolta Magicolor 2350 printing is faded even though a nice image is in the transfer belt and OPC drum; at the end of each printing gives paper jam on transfer error-please help!

When you print stop the printer half way through then check the image on the opc drum and transfer belt to see if it's complete or not, also you may want to check the aidc sensor (sometimes the cable comes loose). I can e mail you the 2300 series service manual (4.17mb) if you reply with your e mail address
