Bests & Worsts Reviews from Amazon

I've been using workhorse HP printers for over twenty years and been quite happy. In February I thought I'd upgrade to the "latest and greatest" feature set by buying two of these 7520 printers. The print quality is fine, the feature set is impressive. But there is a BIG, BIG "BUT": (BTW, I just wasted almost TWO FULL HOURS of my work day with HP "customer support" and got ABSOLUTELY NOWHERE.) I am getting about 210 pages per 564 black XL cartridge (the box says I should get "up to 550" pages). My "photo black" cartridge has had to be replaced TWICE -- EVEN THOUGH I HAVE NEVER PRINTED A SINGLE PHOTO OR FULL COLOR PAGE ON THIS PRINTER. ALL THREE of the color cartridges have likewise needed to be replaced TWICE -- again EVEN THOUGH I HAVE NEVER PRINTED A PHOTO OR FULL COLOR PAGE ON THIS PRINTER. I read in Consumer Reports ("The case of the disappearing ink," August 13, 2013) that this particular printer is THIRD FROM THE WORST in terms of wasting ink of all the printers they tested. Here's the scam: the printer "automatically" cleans your print heads on a regular basis for you. Sounds like a cool feature, right? Well, it's a (I believe) deliberate strategy to use up your ink faster, so that (of course) you'll have to BUY MORE INK. The proof is that my photo black and color cartridges are draining out, even though I always print in "default" (not "high quality") mode, and NEVER PRINT ANYTHING IN COLOR (except incidental logos from bank statements or color s***that you can't NOT print when you buy movie tickets, etc). I also finally got the support tech (who was REMARKABLY unhelpful) to admit that the black "photo" ink is also used even when you're just printing everyday text documents. (He also had the nerve to try to explain the disappearance of my color ink by pointing out that I have printed out 9 "printer status reports" [the only way to find out how many pages you've printed since changing cartridges] since purchasing the printer -- when these reports use a TINY amount of color ink to tell you how much of each color is left in the cartridge!) We've all known for quite some time that printer companies sell you the hardware for cheap, and then rape you on the cost of ink. BUT THIS LEVEL OF RIP-OFF IS BEYOND THE PALE. DON'T BUY THIS PRINTER UNLESS YOU WANT TO WASTE HUNDREDS OF DOLLARS PER YEAR IN INK COSTS!
