This has now been escalated to Canon as a Case # through the printer/copier/scanner dealer.
The initial suggestion was that if we had other version of FM (6,7,8 are on some) installed on the same machines that they might have some conflicts created if they use some of the same library from a prior version when it should be using a the current version (I'm suspect).
Additionally, other machines that had been able print seem to be falling prey to the problem once they have printed x (unknown) number of pages...and have had to switch to the old HP 800N I have temporarily put in place which is working fine.
I truly believe that it is a either a Canon driver or interpreter issue.
Any thoughts, let me know.
