2.2.5. Development
1. Overview
This machine contains a development toner magazine (DTM) [A], which
contains the toner agitator [B], development roller [C], toner supply roller [D],
doctor blade [E], and the toner tank [F].
At toner end, the entire DTM is replaced by the user.
There are two rollers in the DTM: the toner application roller [D] and the
development roller [C].
The toner agitator [B] stirs the toner and carries it to the toner supply roller
[D]. The toner is then carried from the toner supply roller to the development
roller. As the development roller turns past the doctor blade [E], only a thin
coating of negatively charged toner particles stay adhered.

During printing, a bias voltage of -280 V is applied to the development roller
(when a print density setting of Normal is selected). The development bias
changes in accordance with the print density selection (user parameter 12,
Bit 3 and 4).
Since the laser exposed areas on the drum are reduced to -50 V, the toner is
trasnferred from the development roller onto these areas of the latent image
as they turn past the drum.
There is no DTM detection in this machine.
