Dust shield for a printer.

摘要

A dust shield (1) for preventing paper dust from fouling a printer and printhead mechanism is disclosed. In a sprocket-wheel paper drive printer, the sprockets are at least partially encased as they enter and exit the holes in the paper. Paper particles are trapped (7) and then channelled (5) away from mechanisms, such as a thermal ink jet cartridge printhead, whose operation may be detrimentally affected by such dust.
