Over a year and a half of use I have had a series of problems with this machine's scanning functions--first bands (eventually solved); fairly consistent communication problems between my MAC OSX 10.7.5 and the scanner that require annoying and continual manual resets; and now a complete failure to scan from the flatbed to the computer in color.
The problems have mounted with MAC OSX and HP updates. None of the service/support suggestions or online chat groups ideas have resolved this. The functions are fine--when they work, but I would not recommend this printer. Too bad as I've used HP printers for years. This one in my experience is a dud.
