Unreliable and difficult to operate

This printer has prepared a lot of problems. Starting with the very elaborate use of the four cartridges. Although I have used very expensive original cartridges were permanently error messages that the Printer does not recognize / defective etc. would be. Even after checking with hotlines no improvement. Typeface below average, very cheap and failure-prone process. Fortunately, I have completed an additional warranty extension and will return the printer. I will buy only printer with 1x sw cartridge plus 1x triple-color cartridge. In the meantime, I have my old reliable HP G85 reactivated - works flawlessly with favorable Alaskaprint-refill cartridges.
