Abstract
A semi-automatic exit window cleaner which includes a wiper for contacting an exit window. The wiper attaches to a wiper operation mechanism which swipes the wiper across the exit window when an operator accessed compartment or drawer is moved. Beneficially, the wiper mechanism is comprised of a cable which is spaced between two pulleys, one of which also connects to a gear or other rotation train.
Claims4
A semi-automatic exit window cleaner comprised of:
- an exit window;
- a wiper for contacting said exit window;
- a movable mechanical coupling operatively connected to said wiper;
- and
- a drive mechanism attached to said mechanical coupling, said drive mechanism for moving said mechanical coupling when an operator moves an operator accessed element, wherein said moving of said mechanical coupling causes said wiper to swipe across said exit window;
- wherein said operator accessed element is a substrate holding drawer.
3 more elements
A marking machine comprised of:
- a photoreceptor having a photoconductive surface which moves in a process direction;
- a charging station for charging said photoconductive surface to a predetermined potential;
- a raster scanner assembly for exposing said photoconductive surface to produce a first electrostatic latent images on said photoconductive surface by sweeping a modulated laser beam across said photoreceptor in a fast scan direction which is substantially perpendicular to said process direction;
- a first developing station for depositing developing material on said first electrostatic latent image so as to produce a first toner image on said photoconductive surface;
- a transfer station for receiving said first toner image from said photoconductive surface and for transferring said first toner image onto a substrate;
- and
- a semi-automatic exit window cleaner, having:
- an exit window optically disposed between said photoreceptor and said raster scanner assembly;
- a wiper for contacting said exit window;
- a movable mechanical coupling operatively connected to said wiper;
- and
- a drive mechanism attached to said mechanical coupling, said drive mechanism for moving said mechanical coupling when an operator moves an operator accessed element, wherein said moving of said mechanical coupling causes said wiper to swipe across said exit window;
- wherein said operator accessed element is a substrate holding drawer.
