Raised/lowered position detecting mechanism

4.5.1

Document size detection

• The 15 degree Open Detection Mechanism enables the main unit to detect the document
size when the RADF is used as the Original Cover of the main unit, there is the Lever
Actuator provided in the RADF body that blocks or unblocks a sensor to initiate a recon-
firmation of the original size as read by the original size detection sensors.
4.5.2

Raised/lowered position detection

• The Raised/Lowered Position Detection Mechanism uses a magnet installed in the
RADF body to allow the main unit to know that the RADF is raised or lowered. This mag-
net actuates the Size Reset Switch on the main unit to perform this operation.
