I bought the Xerox VersaLink C7120DN a few months ago because I was looking for a good A3-capable duplex scanner with a "proper" feeder and good scanning speed and couldn't find a suitable product. I had also wanted a good A3 printer for some time and the price was right. I am very satisfied: the quality of the printer is comparable to other laser printers, and the scanner feeder seems very good (like the professional machines in the university library). The scanner scans both sides simultaneously and very quickly. The paper is not pulled through twice as with older scanners.

There is NO wifi adapter included with this model. I ordered this separately: Xerox Wireless Connectivity Kit (was under 100 Fr at the time though). The wifi works with it, but it should be noted that the tiny wifi adapter is mounted at the back on the right side of the printer, and if the printer is placed against the wall in the right corner of a room like mine, the wifi reception is not very good because it is shielded by the wall. In the end, I set up a separate wifi LAN access point and hung it on the wall next to the printer and connected it to the printer using a network cable.

Ýes, it is working just as it should. All the described requirements are met with this printer.
