Right Gear module functionality
The Right Gear module has two different functions associated with the Multi-Sheet Tray.
1. The paper drive from the Multi-Sheet Tray into the platen area (until the cut sheet reaches the drive
roller area).
The intermediate shaft in the Multi-Sheet Tray is driven by the drive roller through a gear train
inside the Right Gear module. The intermediate shaft meshes with the Multi-Sheet Tray gear
interface (red gear in the picture) at the end of the train. A swing arm engages the gear train
when the Drive Roller is driven backwards (as shown in the picture), driving the intermediate shaft
forwards. When the Drive Roller is driven forwards, the swing arm disengages from the gear train
and the intermediate shaft is not driven. This action is to prevent reverse paper movement to be
transmitted to the Multi-Sheet Tray.
