Designjet 5500, prints black rectangles on prints.

The customer had originally said the printer was giving issues such as not printing some jobs, or stopping before completing the job. I had them upgrade the firmware and drivers. Now they say that it will print black rectangles of different sizes in different locations on some jobs. Any ideas?

Something like this?:
Crop Circles?

I haven't updated that thread, but the final outcome was that somebody with a local driver had selected "vector" printing. Honestly I didn't know it was there until it was pointed out. =^..^=

Kind of the same principle. Mine are perfect rectangles in different sizes and different places. I think i will ask them to hookup a different laptop. I have not seen it happen printing, but my gut says it is not in the plotter itself.
