After working with me on the phone, and unplugging each of the motors on my non-warranty duplexer, we determined that it was the controller board. I have a Konica Magicolour DL colour laser printer and I have put in a refilled black toner cartridge which works great, but the machine wont go into power saving mode. I have a magicolor w konica minolta printer. I removed the cartridges and vacuumed a large amount of toner from the bottom. If the pin is not in the groove then the unit will draw paper just though the fuser unit then report a jam.

Are your cartridges original Koninca and if so, have they been refilled? I returned them to the plain paper setting and all is well. The item is new and unused. They reduce the clearance and pressure on the fuser rollers for feeding envelopes. I agree, they should woork in either, it is very weird.
