ZS SEMI-AUTOMATIC DOCUMENT HANDLER (SDH)
e Up to 50 sheets of A5 lengthwise to A4 lengthwise or 5-1/2" x 8-1/2” to 8-1/2” x 140
(inch areas) can be loaded in the SDH.

24-1. Document Take-Up Mechanism
e The document take-up mechanism takes up the top sheet of a document set placed
on the Document Feeding Tray and transports it up to the Registration Roller. The
drive for this mechanism comes from SDH Drive Motor MI 0.

24-2. Document Separating Mechanism
e When two or more sheets of document are taken up by the Document Take-Up Roll,
the document separating mechanism prevents the second and subsequent sheets
from being fed further into the SDH. It consists of a Feed Roll, Separator Roll, and
a torque limiter.
e When only one sheet is taken up, the turning torque of the Feed Roll is transmitted
via the paper to the Separator Roll. However, since the stationary torque of the Sep-
arator Roll (torque limiter) is greater than the turning torque of the Feed Roll, the
Separator Roll is driven by the Feed Roll to feed the paper onward.
e If two sheets are taken up at once, the Separator Roll remains stationary because
of the stationary torque of the torque limiter, since the friction coefficient between
the top sheet and second sheet is low. This means that the second and subsequent
sheets are blocked, while only the top sheet is fed in.

24-3. Document Transport/Exit Mechanism
e The document transport mechanism transports the document, fed from the take-up
section up to the Registration Roller, on to the exposure position along the guide
plate.
e The document exit mechanism ejects the document transported by the transport
mechanism out into the Document Exit Tray.
