Hey all,
Got a bizhub C452 with about 400,000 prints total. Can only see this issue when printing on 11 x 17 paper. Tried scanning but the light gray part of the issue doesn't show up, so here's my best description
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. When I print it out I get this problem - the black, red, light blue, and orange all print fine. 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. This happens during only the trailing 3-4" and only in green and blue.
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.
I'm about to change the print board, but just thought I'd throw this up here to see if anyone has ever had this issue????
Added - print board no fix, same issue is seen on the color registration printout - C, M, and Y all separate out more and more on the last 6 sets of registration marks
Thanks for any help
