Good, but: fummeliges tray and envelopes!

Setting up the Mac (OS X 10.9) without any problems, everything works right away, and Wi-Fi. Scan, Copy, ease of use - everything was great! No printing on envelopes possible: however big however - Print quality is in my opinion absolutely satisfactory! Envelopes are not available in the print dialog, and if you try anyway, the envelopes land badly crumpled in the issue, even in thick paper quality or even maps. Is not definitely. Second Smear: The reservoir tray for paper to be pulled to the new charging completely, adjust the guide rails and, in particular, the re-insertion into the printer is fiddly, one must always fear that something could break.
