Development Unit Operation
[A]: Developer Cartridge
[B]: Developer Augers
[C]: Development Roller
[D]: Doctor Blade
[E]: Development Bias Terminal
Each PCU is supplied by a separate developer cartridge [A] (Y, C, M, K). When a
new developer cartridge is installed and the tape is removed, all the developer falls
into the development unit, across the full width of the development unit. Toner is
supplied through a small square port at the front of the development unit (see
section 6.9).
Two development augers [B] cross-mix the toner from the toner cartridge with the
developer and then send the mixture to the development roller.
The magnetic development roller [C] pulls the developer-toner mixture onto its
surface as it rotates.
Near the top of the development unit, the doctor blade [D] cuts and smoothes the
developer-toner mixture to the correct thickness.
The bias from the development bias power pack is applied to the development bias
terminal [E] that is attached to the shaft of the development roller
