C8000 Stopping mid-printing of a job

[InvisSoul]

I'm printing a fairly large booklet imposed. So the flat file is 38 double-sided 12x18 sheet. Every 15 or so the machine stops printing like it has a jam or is out of paper, none of which is the case, but it stops for 30 seconds and then starts printing again for another 15 or so sheets.

I've got no idea why it's doing this. Could it be a memory problem on the Fiery rip side or on the C8000 side?

Anyone have any clues?

Dont sure, but is the machine doing some image quality adjustments?

Not adjustments, it still says "Printing in Progress".
