Query: Canon MF5550 Multifunction

This product is referred to as a "prototype" Well--that's all it should have been--it should have never gotten through the exit doors at Canon. I spoke with a Canon customer service rep. about this product and he said "That's what we get for having someone else design it for us."The envelopes require three settings (2 on the computer and 1 on the printer) to print one envelope--I'll handwrite it, thank you. The feeder tray doesn't recognize label mini-sheets, so I have to throw out the rest of a full size label sheet after printing a couple of labels (bad for the environment, although Canon claims to be an environmentally sound company and expensive!).The most annoying thing is that the printer has to be unplugged and plugged in daily because it goes offline. Most folks at Canon won't tell you why--when they finally tell you what they think the problem is, they say it's not their problem. Oh--I see--you manufacture these devices in a vacuum and suck us in!
