Abstract
A handle or knob is connected to laterally position parallel sheet edge guides so that the distance between the guides is equal to the width of a sheet to which a toner image is to be fixed by pressure rollers. The handle or knob is also connected to an adjustable spring assembly which presses the rollers together in such a manner that the spring force acting on the rollers is a function of the sheet width.
