11. LIFT MECHANISM
When the DJF is opened, the lift springs [A] provide enough force to ensure
that the DJF does not fall onto the exposure glass. When the DJF is closed,
points "➀", "➁", and "➂" are positioned as shown and no upward force is
provided to the DJF.
The position sensor [B] is actuated when the DJF is closed. The copier then
shifts to the document feeder mode. The position sensor also serves as the
reset switch for DJF misfeeds.
After the cover is closed, the APS start sensor [C], which is below the DF
position sensor, informs the base copier CPU that original size sensors in
the main body can check the original size for the platen mode.
When a book or thick original (maximum thickness 60 mm) is copied, the
DJF acts as a cover for the original as shown in the diagram [D]. The
position sensor is turned off during this condition, so the DJF does not
function. The tension of spring [E] returns the DJF to the normal condition
after copying a thick original.
