Bizhub 25 colored lines/background when scanning (with samples)

[AjitN]

Thanks everyone. The lines are not there anymore, just a light blue background. I did clean the glass personally, and I don't think dirty glass could cause a light blue background covering nearly the whole page. I did not try scanning in color off the glass, that is a good idea. Right now the manager is deciding what to do. Have a good weekend.

Which Chemical/liquid you used to clean the glass.
Some leaves colored coating on the glass which may not be easily seen by eyes, one should always clean glass with water after using some cleaning liquid.
Hope this helps
