I bought the X7310. The quality of prints and scans is good. Faxes are also sent good and fast. The software is good and clear for normal operator. The only thing that really bothers you is the (still) can not refill the ink. Although I have refilled the black cartridge, but the software and the printer itself Report an empty cartridge. Well, maybe there are soon a guide like this will be changed. Due to the Nachfüllproblems I give only 3 stars otherwise I would give 4.
