It's very annoying that they don't tell you this in advance
February 2, 2018
My HP printer has always worked flawlessly, and I've never ever had an issue with replacing an ink cartridge. Until now. Apparently, HP has changed the ink cartridges to be zoned for different locations. If your new cartridge has a "Z10" on it, you must have your printer updated by HP. I purchased a set of four ink cartridges, but when I inserted the black one, my printer told me it was "incompatible." I returned it and ordered another, only to see the same message. After 90 MINUTES on the phone with HP tech support, I learn that you must replace all four cartridges with the "Z10" cartridges (whether or not they are empty) and then have HP "reset" your computer. It's very annoying that they don't tell you this in advance. Love the printer. Hate the way they've handled this.
