8. LIFT MECHANISM

[D]
[E]
When the document feeder is opened, the lift springs [D] provide enough
force to ensure that the document feeder does not fall onto the exposure
glass. When the document feeder is closed, points "A", "B", and "C" are
aligned and no such force is provided to the document feeder.
The lift switch [E] is actuated when the document feeder is closed. The copier
then shifts to the document feeder mode. The lift switch also serves as the
reset switch for document feeder misfeeds.
When a book or thick (maximum thickness 60 mm) original is copied, the DF
acts as a cover for the original as shown in the figure [F]. The lift switch is
turned off during this condition, so the DF does not function. The tension of
spring [G] returns the DF to the normal condition after copying a thick original.
