We just brought in a MFX-4550 for evaluation. I printed off all the comments on this page and gave them to my service manager, and he thanks you for all the good insight. We have a tip to share back, and Ryan and Art will be glad to hear this. That annoying "confirm page size" screen that you get every time you open a paper drawer? You can turn it off. Go into the Machine Set-up/Admin Set-up screens, and poke around and you'll find it. We'll let you know how the rest of the evaluation goes.
