A strip assembly for a printing device having an endless type band frictionally driven by drive and idler pulleys between print hammers and a platen comprises a wear strip and wiper strip attached together at a common end. The wiper strip has a wiper portion extending from the point of attachment which terminates in a scraper edge. A retention device mounted in proximity with the drive pulley comprises means connectable to the common end to hold said wear strip under tension and said wiper strip in spring loaded condition with the scraper edge in contact with the drive surface of the drive pulley for cleaning wear strip residue and other deposits from the pulleys and the type band.

Disposable strip assembly and retention device for a line printer

An ink jet printer employs a wire mesh gutter electrode assembly and a wire mesh high voltage electrode, each having angled or skewed configurations geometrically related for providing a relatively narrow constricted path for ink droplets, so that charged and partially charged droplets, which are not used for imprinting, traverse a short path and are effectively captured and collected for recirculation and use in the ink recording process.
