6.2.5 Development Roller Drive
Because the development unit is a revolver unit, there is only one
development motor [A], which drives the color development roller that is at
the development position.
When the development motor turns, the development roller which is at the
development position [F], the dual mixing roller [B], and the transfer auger
[C] are driven via idle gears 1 [D] and 2 [E].
While the development unit (the revolver unit) rotates, the development
motor [A] rotates the idle gears [D, E] so that they will mesh with the gears
on the revolver unit easily.
If the development motor does not rotate, the gears will not mesh smoothly
and toner may be dislodged. This toner may be attracted to the drum,
leading to dirty background.
