Liquid ink printer transport belt cleaner

摘要

A cleaning apparatus for cleaning a transport belt in a printing machine of the type in which liquid ink is deposited on a recording medium moved along a path by the transport belt. The cleaning apparatus located next to the transport belt cleans a first surface and a second surface of the transport belt when ink and/or other contaminants collect on the belt. A sensor senses when the belt needs cleaning. Interior side walls of apertures within the belt which enable vacuum transport of the recording medium through the printing machine are also cleaned. The cleaning apparatus includes a first cleaning device having a flexible web for cleaning the first surface of the transport belt and a second cleaning device having a flexible web for cleaning the second surface of the transport belt. The sensor includes a length sufficient to sense contaminants along the width of the transport belt.
