"So far, a great buy"4.5 starson by johnmesich
Pros: VERY quick printouts, instant-on is awesome, even if the unit is waking up from power-save mode, ROCKS on quick color or B&W printouts. Network installation took 5 minutes out of the box!
Cons: The front fold-down feeder tray is really flimsy and appears cheap. Not sure if I'll expect a problem with that in the future.
Summary: I picked this thing up after thinking long and hard about getting the Multifunction HP or the Multifunction Canon, either in Color Laser. I am sick of maintaining 3 or 4 different machines that I have right now. I went to OfficeMax to buy the HP LaserJet 8420, and ended up being really impressed with the speed and instant output that this unit provided. Text and graphics all looked good, and I like the fact that you don't have to worry about replacing a separate imaging drum, because of the single-pass setup in this unit. I think the cartridges fit in very well, and the design (although it looks fragile) is pretty slick. Paper jams, although I haven't had any yet, look very easy to clear by opening the front door.
The menus and prompts give you tons of options, and this thing is pretty quiet, even when printing, it sounds like a normal LaserJet 4000n that I used to have. I had a problem printing envelopes and paper mis-feeds with the *ugh* OfficeJet 7320 that I have had been testing for the past few months, and so far, this one seems to print them fine. It auto-detects the envelopes and the paper size, which is good too.
I'm still skeptical, but so far, this unit looks very promising and very, very fast.
