A holographic display module is incorporated into a machine with independently operating subsystems, and used to provide an indication of the status or location of the machine subsystems. In one embodiment, a xerographic copier incorporates a holographic display incorporating an outline of the machine. A liquid crystal panel is aligned with the holographic display and selectively addressed in conjunction with signals from the copier subsystems. An illumination subsystem is optimized to provide diffuse illumination of the display.

For a copier with a dual mode document handling system for handling both computer forms web (CF) and individual document sheets, there is provided a plural mode integral unit system easily mountable to an end of the copier for handling the input and/or output of both types of documents and providing improved work space. The system includes a first document stacking tray providing both an operator work space and a tray for individual sheets fed to or from the copier document feeder, and also defining a CF guide aperture therein for CF document feeding to or from the document feeder. The system also includes an integral second document stacking tray for properly supporting a fan-folded stack of CF in a operating position. This second tray is pivotally mounted to the first tray and compactly closable thereunder without interfering with the operation of the first tray to provide an attractive and compact closed unit. The second tray is repositionable into a substantially horizontal operating position appropriately spaced below the first surface and centrally below the CF guide aperture and in CF feeding communication therewith for improved CF feeding/stacking. A simple suspension system is provided to suspend the second tray in the operating position from the first tray so that it does not have to cantilever support the weight of the CF stack.

A toner dispenser having a rotatable cylindrical dispenser roll and an automatic low toner level indicator comprising a lamp and photocell mounted in opposed walls of the dispenser adjacent the bottom of the dispenser housing. The lamp and photocell are separated from the toner in the dispenser by transparent windows. A wiping arrangement is provided inside the dispenser to periodically clean the windows including wiper pads biased into contact with the windows and movable periodically back and forth across the surface of the windows in response to rotation of the dispenser roll.
