Larry:
I've test a few hundred so far with #10's from the paper tray. So far so good, I will explain to the customer all of the pro's and cons, and most likely the system will need more service. It's either this solution for the customer for about $5K with all of the paper trays for the C431dn or a solution from PB (inkjet and loud) for about $14K.
I'm stretching it but sometimes we need to see what these systems can really perform. I'm thinking it can with all of the right settings.
Thannx for the FYI on this
