Abstract
The time periods between energization of an optics clutch and activation of a scan switch at the end of scan position and between de-energization of the optics clutch and actuation of the scan switch at the home position are provided. Representations of the time periods are continuously displayed during a copy run. The last timing periods of a copy run are temporarily stored until the next copy run. Upon entering a diagnostic mode, the machine will produce a copy in the normal manner and display a number corresponding to the forward scan and return scan or flyback time periods. Through suitable conversion, the scan time in milliseconds can be provided.
Claims11
In a reproduction machine having a scanning optics system, a diagnostic method comprising the steps of
- providing a signal at the start of scan of the scanning optics system in the forward direction
- activating a switch at the end of scan, the switch providing an end of scan signal,
- providing end of scan and beginning of scan signals, for scanning of the scanning optics system in the reverse direction,
- storing signals representing the scan time in the forward and reverse direction, and
- displaying the representations of the scan time in the forward and reverse directions.
A reproduction machine having a plurality of components and a photoreceptor cooperable with one another to produce impressions on support material and including a scanning optics system comprising
- a scanning carriage for scanning a document to be reproduced,
- a signal provided at the beginning of scan, a signal provided at the end of scan, and
- means to continuously display signals representing diagnostic scanning information.
