Abstract
An apparatus for recirculating developer material in a developer unit. The apparatus includes a first transporter for transporting the developer material in a first direction, a second transporter for transporting the developer material in a second direction opposite to the first direction, and a mover for moving the developer material from the first transporter to the second transporter.
Claims30
An apparatus for recirculating developer material in a developer unit, comprising:
- a first auger for transporting the developer material in a first direction;
- a second auger, for transporting the developer material in a second direction opposite to the first direction;
- and
- a first paddle extending outwardly from said first auger, for moving the developer material in a substantially radial direction from said first auger to said second auger.
A particle transport comprising a spiral auger including a first vane section for moving particles in a first direction, a second vane section for moving particles in a second direction opposite to the first direction, and a paddle connected to at least one of said first vane section and said second vane section to move particles substantially transverse to the first direction.
A printing machine of the type having developer material recirculated in a developer unit, wherein the improvement comprises:
- a first auger for transporting the developer material in a first direction;
- a second auger for transporting the developer material in a second direction opposite to the first direction;
- and
- a first paddle extending outwardly from said first auger, for moving the developer material in a substantially radial direction from said first auger to said second auger.
