(2) Revolver H.P. Detection

The revolver H.P. sensor [A] is at the front side of the development unit

(figure 1). The revolver home position is the position at which Bk toner is

developed on the drum (figure 2).

There is a notch [B] on the revolver frame ring [C]. After the revolver H.P.

sensor detects the notch, the revolver rotates 20 degrees counter-clockwise,

then stops. This is the revolver H.P. process and is performed after every

copy job. But after a black and white copy job, this process is not performed

(the unit is already at home position).

After the main switch is turned on or the front cover is reset (copy jam

recovery), the revolver H.P. process is also performed to send back the Bk

development section to the position for development.
