6.2.9 Revolver Positioning
This section explains how the revolver moves the various color toners into
position in the various modes. For a fuller explanation of how the revolver,
drum, and belt move in each of the modes, see the "Transfer Belt Unit"
section.
(1) In 1C Mode (Bk, C, M, and Y)
After the start key has been pressed, the machine moves the selected color
development section to the position for development. In black and white
mode, the development unit does not rotate because the Bk development
section has been already moved to the position for development by the
revolver H.P. process.
The first copy speed depends on the color, because the time needed to
rotate each color into position for the first copy is different. (See the table
below)
After the copy job, the machine performs the revolver H.P. process to
reposition the BK development section. In black and white mode, the
revolver H.P. process is not performed, because the revolver is already at
home position.
