Abstract

A thin metal ribbon shield for mounting in a standard data processing printer ribbon guide. The ribbon shield has a short insert tab and a long insert tab, and is particularly designed for ease of installation and removal. The thin metal ribbon shield is durable and permits printhead gap settings from the paper of the minimum distance capable in a printer. The ribbon shield is unlikely to kink during installation or removal because the stress when bending the shield is at the juncture of the long insert tab and the ribbon shield, rather than down the middle of the shield face.
