scanned image has a vertical gray stripe

[MichaelT]

The scanner was not used for about two months.  Now we notice the first scan has a vertical black stripe, and later scans have a much lighter gray stripe (as shown in the attached image).  The center of the gray stripe seems to be located at the center of the document glass (near the 4" mark).  Please advise.

Hi,

If you are sure that the scanners glass are very well cleaned, you will need a tech to disconnect/reconnect the flat cables from CIS sensors (at the CIS side and at the Board side)

I cannot find a tech in our small town. Are there directions on removing the scanner glass on WorkCentre 6515 ? Thanks for your help.
