Simple Dampening of Mechanical Noise

Problem is that of a moving mechanical part (part is supposed to move freely by gravity) that makes rattling and scraping noises when the mechanical unit is taken out of the box and shaken about. This is the out of box experience for a thermal printer. It has a loose part that is supposed to be loose and move freely for correct operation. The part is the extra wall mount brake that comes into play by gravity when the customer places the printer on a wall. The brake decelerates the top cover in this attitude while in a table mount mode the extra brake swings back to a neutral home position. A thin plastic sheet is placed under the moving part and has tabs bent up at the end travels of the part to dampen and keep the ends from hitting a hard stop. See the following figure (figure
