Bizhub C452 - background in one corner [scanning from flatbed]

**-ph-** · 03-12-2013

Hi,

This afternoon I ran into this problem, when making an A3 scan from flatbed there's one corner with background [the corner nearest to the operating panel] if I make the same scan from the feeder I have no background. The feeder closes correctly, I checked and cleaned the optics and ran through stabilisation and grad. adjust, but no result.

check image below:

any ideas?

Bent scanner. Someone's been leaning over it while taking copies.

yep, seen this before. I agree with mrwho.

Or if its a new machine, its been damaged in transit and I'd write it off or reject it.

Thanks for the response, i'll try to bend, hope it will work out.

Ditto that. Until you get it focussed properly it won't complete gradation. =^..^=

had one of these machines do the same thing at run-up
tried replacing ccd unit, all associated cabling, none of it worked
didnt check the framework, but we just sent the machine back and got a replacement.

for your sake, i hope its not a field machine, because i wouldn't want to have to replace the framework

problem solved, it was just a matter of bending the scanner back in its correct position, trail and error, luyckily it was pretty easy.

We've had a nutter sit down and graft the top end of one scrap machine onto a field machine, it wasn't actually that hard but just quite a bit of time required.
