After seeing my involuntary manslaughter "old" C5100 DN can use only limited (I killed him with low toner), so there was a new and of course again from the same manufacturer. I chose this model because I wanted to have additionally an additional cartridge to printed stationery not having to perform awkward every time by hand. As usual excellentes aftersales behavior of Amazon, unit came as advertised. A huge box! And it is difficult to even know who it is in the cross, really should take seriously and carry the pictogram for two. Connected, IP address taken as is, drivers from the included CD installed- ready! No Kram and Gedödel, simply power switch on and go. So it must be! The additive cartridge simply logged into the driver properties and then also that was done. Attention: My typing does not use a cheap toner! Who buys cheap, buys expensive! This is a law for centuries. Yes, toner itself is unreasonably expensive, but cheap toner will destroy the device and thus the new purchase is necessary. Since Kyocera's ceramic drum "obviously millions of years" keeps to Wirtschaftlichgkeitsfrage is not. We are two companies that use the printer and had already Epson, HP, Canon and Brother laser printers in use. Kyocera was the only company that convinced us and accompanied reliably for years. No theater, no defect, no fuss, just Print.
