6.8.1 OVERVIEW
1. Doctor blade
2. Developer hopper
3. Mixing auger (right)
4. TD sensor
5. Mixing auger (left)
6. Development roller
This machine has four independent development units, one for each color. Each
contains 280 g of developer when new. The developer in each unit is supplied to
the development roller by the two mixing augers and attracted onto the surface of
the roller.
The photoconductor gap between PCU and development roller is determined by
the drum positioning plate and the rear shaft, and is not adjustable in the field.
The TD sensor and center ID sensor control toner density. Each development unit
has a TD sensor.
The diameter of the development roller is 18 mm (circumference about 56.5 mm).
