This device creates a new benchmark in the disadvantage of the user. I was (is where the economy of the device specifically stated) after all the praise in the online available devices tests surprised at how strongly the ink consumption is actually. Either was tested superficially, or this test releases are bought. You certainly have nothing to do with reality. In fact, it's like my Vorrezensent writes: If a color cartridge is empty, you can not even solid black print. In addition, the ink cartridges do not have the capacity that is specified. Since the device several times in the middle of the night to "self maintenance" leapt (it is connected via Wi-Fi to the network), although all computers were made, it is very likely that the devices have a feature as controlled abrasion / controlled consumption. Apart from this, the device is extremely loud (you have frightful colleagues warn that one thing prints the same. The soundscape reminiscent of the printer of the 80s) and still needs a couple of hours Stand By forever to get into gear. For a monochrome black printing in "draft" quality the device whopping two and a half minutes, including the lengthy preliminary instrument checks, which can not be switched off needs. Super annoying. Conclusion: My last unit of Lexmark.
