attraction moves the developer to the surface of the roller.
The drum positioning plate and the rear shaft set the photoconductor gap between
the PCU and development roller. It is not adjustable in the field.
The TD sensor detects toner density. Each development unit has a TD sensor.
The diameter of the development roller is 18 mm (the circumference is
approximately 56.5 mm).
