MP Error and Different Paper Sizes

If you add / change paper in either the printers or copiers, there is a guide bar that keeps the paper in the right place.  Usually the guide bar is in the right place and should be left there.

 If you change the size of the paper (legal paper, etc.) you need to move the guide bar.  There is a special hole that it will snap into.  The copiers and printers have sensors that detect this placement and it tells the equipment what size paper it is.  If the guide bar does not snap into the hole properly, the equipment is confused and does not work properly.  This leads to the MP error (Manual Paper) on the printers and errors I forget the names of on the copiers.

 Hence, it is good to be careful when you are messing around with paper sizes.
