I tested its various functions: scan, copy, print, and have not encountered any problem. His promises are kept.
The prints are done very quickly and are of very good quality. I had the opportunity to test different paper weights ranging from 80g to 230g and has no problem. The duplex function is very convenient: you can, if desired, run 50 PDF, click the "Duplex" and the printer handles it all alone (so we do not lose time) to then find her stack of freshly printed documents properly. This is a significant time saver.
Contrary to some reviews - I really do not understand - I find that the price of prints is really cheap. I just finished the XL black cartridge supplied with the printer, I could carry with it (at least) 2300 impressions, as expected. This XL black cartridge costs only 24 pennies! This amounts to 0.01 printing! I find it very cheap when compared with other printers, certainly less expensive to buy, but the cartridges cost an arm! If you make a lot of impressions, I advise you to buy a more expensive printer but will quickly pay for itself when you see its low printing costs. Print at home even became cheaper than calling in a specialty store that deals in large prints (and with which the price of a print is double: 0,02 feel I compared before buy).
I advise you strongly this printer you will not be disappointed (e)!
PS: However, I have not yet tested the wifi function, so I can not comment on that.
