Do any other computers also print to the same Bizhub? If so, are they affected in the same way?
If only your computer is affected, then try deleting the printer from your computer and reinstall the latest printer driver for the C552 from the Bizhub website: http://www.biz.konicaminolta.com/colour/c652_c552_c452/
Let me know if that resolves the problem?
The direction of the conveyor belt is set at the factory, and as far as I am aware it is not possible to reconfigure a machine to adjusting the direction of the conveyer belt at all.
