Theory of Operation
Paper Lead Edge Adjustment
When paper is fed to the Transfer section, the paper lead edge is aligned using the
buckle method in the Registration section.
The buckle method puts the paper that was fed and transported from the trays or
the Tray 1 against the Regi Roll, and buckles the paper. By rotating the Regi Roll
with the paper buckled, the paper can be transported with its lead edge aligned.
Paper Transport from the Registration Area
After the Lead Edge of the transported paper has been aligned in the Registration
section, it will then be transported at the appropriate time by the Regi Roll to the
Toner Transfer section.
The Regi Roll rotates from the drive that is provided by the Main Drive Motor
through the Regi Clutch.
