We have the 8860 DN in our small home office for about a month now and are very, very pleased. The page counter is over 2000 and we haven't had a single paper jam, even when we used a special paper that typical jams in our printer. We have used it mostly for copying, but we also use it for printing, scanning, and of course faxing.
The auto-document feeder works like a charm. I have only had one jam in the document feeder, but that was when I was using the duplex option to copy a 120 page booklet that had been stapled together. I expected to have to hand-feed it to keep it from jamming, but I laid the whole stack of about 30 sheets (4 pages to each sheet) in the document feeder and it just purred away, only missing once. I was extremely impressed. On regular paper I have never had the unit jam, either in the ADF or in the output.
I have copied about 160 pages at once and they stacked up nicely in the output tray with no paper jams. The faxes are sharp and crisp, and the memory-dial is very easy to program and can actually be done from a computer using the Ethernet or USB connection, both of which are standard on the machine. A parallel port is also standard. The internal page counter is also a nice feature, which counts total number of pages output, as well as how many pages have been printed, copied, or received on fax. I have had no complaints with this unit and with a speed of 30 pages per minute and fast faxing, it has been a great time-saver. The Duplex option (standard) is also a great time saver and works great.
Update April 4, 2008: Over 29,000 copies later, the circuit board finally went out and I had to replace the machine. In that time there were a total of 18 paper jams inside the machine, and 70 on the document feeder, which we used all the time. Since I had just replaced the drum unit, the machine cost me a little less than 4 cents per copy to operate. Each drum runs for 25,000 copies so this cost would have dropped lower had the machine lasted. I would have no problem buying another machine.
