Abstract

In the design of small copiers it is desirable to reduce all critical adjustments. This greatly reduces assembly costs in manufacturing by eliminating the labor associated with making the adjustments. In addition, it is advantageous not to have adjustments such that field installations and repairs can be done quickly and accurately and with a minimum of specialized training. The figure illustrates a general machine schematic in which this may be accomplished by using'a single reference point for the various subsystems in floating the machine subsystems independently from the frame structure against a single rigidly held system. In the figure the photoreceptor module 10 is rigidly held in place and the reference point for one or more other subsystems may be taken as the center of the photoreceptor drive roll 12. The developer module 14 comprising two magnetic brush developer rolls 16 and a delivery roll 18 is biased upwardly by springs 20 into developing engagement with the bottom run of the belt in photoreceptor module 10. On top of the photoreceptor module is the optics module 22 comprising a SELFOC lens 24, an exposure lamp 26 and a charge transfer corotron
