Abstract
An adaptive paper slot device providing adjustment for the location of paper slot feeds to and from a printer located within an acoustic silencer enclosure to permit using one enclosure with a number of printers having different paper feed locations. The adapter device is mounted on one wall of the silencer enclosure and has a number of adjustable horizontal bars which cover the end of the enclosure with horizontal slots between the bars. The bars can be relocated to move the slots for paper feed to any desired vertical location. The inner surface of the bars is covered with sound absorbing material to maintain the integrity of the acoustic silencer enclosure excepting for the proper feed slots themselves.
