Abstract

Electroreprographic machines are frequently subjected to abuse by operators who occasionally slam covers or doors, either because they are ilnaware of the weight of the covers, or even as an expression of frustration with the operation of the machine. Typically, a damping mechanism designed to prevent the rapid closure of the cover or door will counteract the weight or applied force. However, fatigue of such damping mechanisms results in an inability to counteract the applied force, which may actually be another cause of the rapid closure of the covers and doors due to their own weight.

IMPROVED MACHINE Proposed Classification RELIABILITY USING FORCE U.S. C1.355/206 FEEDBACK Int. C1. G03g 21/00 Michel J. Denber

Electroreprographic machines are frequently subjected to abuse by operators who occasionally slam covers or doors, either because they are ilnaware of the weight of the covers, or even as an expression of frustration with the operation of the machine. Typically, a damping mechanism designed to prevent the rapid closure of the cover or door will counteract the weight or applied force. However, fatigue of such damping mechanisms results in an inability to counteract the applied force, which may actually be another cause of the rapid closure of the covers and doors due to their own weight.

Accordingly, the present disclosure is directed at a method for recognizing when covers or doors are slammed on the machine and to provide feedback when this occurs. It is proposed that a commonly known vibration sensor be added to the electroreprographic machine to sense when the machine is exposed to excessive vibration from, for example, the slamming of a cover or door. The vibration sensor may be a mechanical type, or an acoustic type (microphone). In one embodiment, the feedback could be a visual indication via an LED, LCD, or CRT display on the user interface. Alternatively, the feedback could be an audible tone, or prerecorded message generated by a low cost speech synthesizer.

The output of the vibration sensor may also be...
