After owning a seperate scanner and printer for awhile, I bought this combined unit to save some desk space. The price seemed right, and I didn't need the extra fancy features of the more expensive units, such as the LCD screen etc.To me, HP should have removed the memory card slots and put more engineering into the paper feed tray. My unit has worked flawlessly for about a year (or maybe less). I was very excited about the copy feature and scanner as it worked so well.But now as I sit, the paper tray will not feed paper. One sheet, multiple sheets, the tray will not grab the paper. I suspect to fix this unit, it will cost more than what I paid for it originally. The scanner still works wonderfully.If you search online, there are some other people that have experienced this same thing. I haven't even burned thru the original ink cartridges yet. Very disappointing.
