I see no one has responded to this post yet. So, at this point I would recommend contacting your local Xerox Support Department to speak with a Product Specialist for more assistance. Please call 1-800-821-2797
I've been running GPA's 11 Pt Stoplight paper for a number of years on my Iridesse with no problem. Sometime last year they changed vendors and since then, I can't get it to run, sometimes it will run 1 side for a couple of sheets only to jam in 3A and then refuse to run another single sheet of it and sometimes throw a subsystem error at me requiring restart. I've even tried it on our Versant 280 and it'll run 1 sheet out, then jam and eventually give me a 077-311 error code, making us restart the machine.
Has anyone had this problem and what workarounds have you used? I've tried as many different options as I can think of to no avail, TIA
