Had a wierd problem on a 250 last week. Task with 14000 total prints, when ever you would copy there would be just a greyish black perfect box with crazy data miniboxs inside. If you would print a doc, it would be fine. I tried reseating the dimms on main board and turned it back on and it worked for 20 copies, came back. Reseated the memory dimm worked for 30 copies came back. So wierd, re-updated to 6.0 and tried again. Worked for 100 and I thought that I was golden. Ran some through the AF and the first 2 were ok and then came back. So after all that, nothing. Thought some more and relized that I had the dual scan doc feeder, put in a 2 sided original and guess what, one side perfect, one side garbage.
The end of the story is the ISC board that controls the CIS was flaking out. Took one out of our demo to get them going and it has worked perfect. Ordered the board and I am putting it in tomorrow.
