2.  Operational descriptions
This converts the electrostatic latent images on the OPC drum gen-
erated by the laser (writing) unit into visible images with toner. 
Toner and carrier in the developing unit are stirred and transported
by the mixing roller.
By mixing and transporting, toner and carrier are negatively
charged due to mechanical friction.
The developing bias voltage (AC component and negative DC
component) is applied to the developing roller.
Negatively charged toner is attracted to the exposed section on the
OPC drum where the negative potential falls due to the developing
bias.
If the OPC drum is not exposed, the negative potential is higher
than the developing bias voltage, and toner is not attracted.
3.  Disassembly and assembly
Be careful not to attach fingerprints or oily dirt on the DV roller sur-
face.
A. Development unit
1)
Open the front cover.
2)

Check that the lock is released as shown in (A).
Loosen the blue screw, and open the drum positioning unit.
* When the lock is not released, use a screwdriver to turn the
screw (B) counterclockwise so that it is fit as (A).
