I've tried the firmware, main PCB, laser unit, laser unit drive board, all imaging unit, black drum, developer unit, transfer belt, and transfer belt drive unit. This happens during only the trailing 3-4" and only in green and blue. The trailing 4" of the blue and green you can see the black "showing as a light gray on print" starts slowing separating out so that by the end it is mis-registered by about 2mm. When I print it out I get this problem - the black, red, light blue, and orange all print fine. I created an 11 x 17 text document with lines of text - about 3-4 lines of different colors text -black, blue, red, orange, light blue and green. Tried scanning but the light gray part of the issue doesn't show up, so here's my best description Can only see this issue when printing on 11 x 17 paper. Got a bizhub C452 with about 400,000 prints total. 2Set FUSER DRIVE GEAR KIT FOR KONICA MINOLTA BIZHUB C452 C451 C550 C650 C552 652 72.12 Free shipping Genuine Konica Minolta Bizhub Cyan Toner Ink A070430 NEW TN611C C650 C550 C451 55.93 Last one Free shipping New Genuine Konica Minolta Bizhub C20 20P Fuser Unit A06X015, A06X016, A06X017 139.
