Printer with acceptable Druckergebebnis but often stains and paper clogging

So the print result speaks for the printer. I am a student and to rely on scripts that are published often in the evening before the lecture, print quickly. The printer prints quickly and eigentlicht quite sharp, but lubricated (every 3rd printing approximately) at the bottom of the sheet.
But that is by far the most annoying that the printer when printing often to very often eats paper. By that I mean that he crumpled paper during drawing and this so verstopt the printer.
Since I often print long scripts with duplex printing, this is terrible, because then you have to restart the print because the printer will continue printing not easy, but not finished it. Often I sit in despair before the device and try printing again to start, but my long press on the continuation button does not always work or rare. But one wants to print a new document, he has memorized, by some miracle the old printing namely suddenly the other side (since I have selected (manual) duplex printing. Printing can not cancel on Windows. It is a the printer would try to finish the job by force.

Summarizing:
