I have Samsung ProXpress m3870fw. Half the times I try to print, there is a jam. Sometimes I just have to open the papers tray and remove the jammed paper, and sometimes the jam is on the rear.
I am using A4 80-gram paper.
I tried to remove all the removable parts of the printer and see if there is a paper that stayed there and causes to the jam, but there was nothing.
There is something to do?
(Sorry if my English grammar is not very good...)
Thank's!
