Abstract
A system and method for user friendly replacement of printer platen rolls includes a roll assembly having a support shaft with a bearing seated in a flange at one end. A crescent notch in a printer chassis receives the shaft into an interior of the notch. The assembly is moved axially so that a flange neck nests in the notch with a flange lip contacting a surface of the chassis. A lock contacts the lip to prevent axial motion of the assembly when installed. An opposed side of the shaft is placed in a bearing on an opposite side of the chassis.
