I have had the unit for about a week in continuous use and have to say that he deals very economical with the ink reservoir. I still have about 90% black and 95% of each sub-color left. The scanning function is also optimal. Everything is top on my MacBook. The ADF works perfectly and the sheet tray is filled to the brim. With active use once 10 leaves you send to the printer in order, it immediately goes into highest potential and provides good print results in a short time.
I am to come to the conclusion, very satisfied with the device and hope that he will continue to accompany me for many years. At this time nobody - unscrupulous buy recommendation to potential buyers. If anything changes, I'll edit this comment.
