Help with Bizhub C650 - Bad Prints (Urgent)

[stryder]

Hi guys, I need your input on a situation that I have on a C650. Basically, it is printing out this demo page photo(3).jpg. I've tried changing the, Drums, MFP Board, HVPS, PWB-MC, Laser Write Unit, Power supply. But none of them solve the problem. Then another problem occurred, the machine boots up to a blank screen with the start button lighted up orange and there is power. Any help would be greatly appreciated. Thank you

not the belt, not the transfer roller, not the fuser... out of options other than a firmware update...

The blank screen....... Now I'm saying this in a very smokey voice "sounds like you have the NVRAM blues"! Try hitting the firmware and /or running the NVRAM recovery program.

On the off chance you get this pig on its feet try stopping a copy midway through, yank the t-belt and see what the image looks like. If its good look towards the t-roller or possibly and HVT issue.

Fixed the issue but now the scanner prints out with a pink fuzz on the whole page. only on scans on both glass and adf. prints looks good. changing a working ccd board didnt work. receding the plugs on the board next the where the adf plugs into made the scan image worst, so will try out those first. thanks for the inputs

And all these problems showed up at once? Just to make sure check the scanner to MFP connector on the right end of the machine I have seen them for what ever reason loosen up and create weirdness. You said you corrected the blank screen issue, how, what was the prob?

Re: Help with Bizhub C650 - Bad Prints (Urgent)

The blank screen was due to the mfp failing, so had to put another mfp in and is working perfectly fine now. But I still have this problem on the scan photo(4).jpg. Prints and everything comes out perfect but the scan is bad. tried changing ccd board, the other boards next to adf plug, even the unit in the middle of the scanner and it still comes out like this. any help on this one would be nice.
