I've had this unit for over a year and use all the features regularly. I used to have it wired to the router but now have it connected over wifi and haven't noticed any difference in terms of speed or reliability. I have a Windows Server machine on the network that acts as a print queue and smb/cifs file share to store scanned documents. There are two minor issues with the 6015NI. The first issue is that sometimes when it is in energy saving mode, it does not wake up when the fax line rings or when you send a print job to the printer. You need to switch off and on again for the unit to recover. The second issue is that the document hopper sometimes feeds in two or three sheets at a time, especially if you're scanning thinner paper like invoices, meaning that the resultant pdf is missing pages. It would be a great improvement if future models had an adjustment for sheet thickness to mitigate this. On the plus side, the fax quality is as good as you'll ever get on G3 and is fairly rapid. Scanning to a Windows network share is easy and the scan engine is fairly quick. This unit will scan a 10 page document in around 3 minutes at 600dpi and then encode to pdf and transfer to the network in under a minute. That's quite a lot quicker than the huge MFD I have at my main office. Printing is reasonable. It's not blistering fast but it's a small inexpensive unit so I expected this. It's a shame there isn't the option to add a duplexer as double sided printing requires a bit of discipline to get it right. Setting up print profiles will help conserve toner which is not exactly cheap but still better value than the hp 3505 it replaced. There is a web interface so you don't need to do all the configuration on the little front panel thankfully. There are so many features and alternative ways to do things that you really do need to spend 15 minutes reading the manual to get the full benefit.
Drivers for Linux were released only once, for one version of the Linux kernel, for printing only. Never updated. Xerox never released driver for scanning. As I know, Xerox did not help external developers in creating an open driver for this device. I'm still using it because I can buy cheap aftermarket toners. I will never buy Xerox. Neither for the home nor the office.
