Summary: My 6510 jammed which caused the plastic holding the paper feed gear mechanism to break. There's no fix for this as the unit was made to replace, not repair. This is my second HP printer both which have now failed. I'm of the belief that most $200 and below printers are simply throw away after the warranty period. If you're lucky it will break while in warranty.
Summary: I really wish I had read the reviews before buying this--I've had it less than a year and it stopped printing in black ink, and now doesn't print at all. And this is after i went out and bought new ink because I thought it was because my ink was low. Don't waste your money on this piece of junk.
Do not purchase without at least a 3 year warranty

Summary: Do Not Buy!!! i repeat DO NOT BUY!! Yes, it works great for a while but the black ink print head WILL CLOG UP. It is NOT user serviceable. Try googling MY 6510 WONT PRINT BLACK and see the sea of frustrated owners and HORRIBLE HP customer support/online forum support.
I was willing to deal with the cost as long as the prints were nice. Then things went from bad to worse

Summary: PLEASE DO NOT BUY THIS PRINTER!!! We bought this locally just over a year ago. According to my print page I have only printed 982 pages. I have replaced all the cartridges 4 times. At $13 for 4 cartridges, that is 21 cents a page! I was willing to deal with the cost as long as the prints were nice. Then things went from bad to worse. Like many others, I found that right after the warranty expired the printer stopped printing black ink.
Black ink stopped working. Breaks just after warranty

Summary: Started out great with great reviews when I searched it almost 2 years ago. Now, my black stopped printing all of a sudden and all I can find are complaints about how common it is and HP has NO SOLUTION for it except buy a new one! When I mean common, I mean EXTREMELY! People have problems right after the 1 year is up and HP customer service is horrible. I'm so sick of talking to foreigners who can't speak English and can only read from a screen as to how to fix it.
