Here's a strange one:
I have (4) documented occurrences in a year (and 8 months in between). Two color scans, one black & white scan, and one black & white copy. This customer scans sets of 1000 pages or more. That's when the problem occurs. In the last sample scans turned solid black on page 893, then on pg 943 turned to gray "noise". As far as I can tell there is none of the original image in the problem scans. The samples that you see are all oriented LT (portrait), and scanned the same.
I've been a bit at a loss as to how to proceed on this. Earlier I went through and cleaned and re-seated all the connectors on the CCD and SLG. It's hard to justify ordering $1K boards when it occurs so infrequently.
I see the most likely choices as the CCD, ribbon cable, and SLG.
I have not been able to repeat the problem after a lot of scanning, so I have no idea if a change of settings might help (or not). There are no errors or jams for the time period of the anomaly, so diagnostics is not of much help.
Has anyone seen this?:
