The document placed in the hopper actuates the document sensor.
After one second, the pulse motor starts to the paper feed roller.
The document is automatically taken up into the mashine, and stopped
at the document sensor.
When a specified number of pulses are received from the document
sensor after the document lead edge is sensed.scanning
is started.
When a specified number of pulses are received from the document
sensor after the document
rear edge is sensed. Scanning
is termi-
nated and the document is fed through.
If the document sensor is active (i.e.,another
document is in the hop-
per), when the preceding document
scanning is completed and it is
fed out, the next document is taken up into the machine. If the docu-
ment sensor is not active (i.e.,there
is no document
in the hopper),
when the document is fed out
,
the operation
is terminated.
Hopper mechanism

Fig. 2
The hopper is used to align documents
with the document guides ad-
justed to the paper width.
NOTE: Adjust the document guide after setting up the document.
3-2. Automatic
document feed
1) Use of the paper feed roller and separation
rubber plate ensures
error-free transport and separation
of documents.
The plate spring
presses the document to the paper feed roller to assure smooth feed-
ing of the document.

NOTE: Double-side coated documents and documents on facsimile re-
cording paper should be inserted manually. The document feed
quantity may be changed according to the document thickness.
Documents corresponding to a paper weight heavier than 84.3kg (74.39/
m*
)
and lighter than 135kg (1579/m')
are acceptable for manual feed.
Documents heavier than 135kg in terms of the paper weight must be
duplicated on a copier to make it operative
in the facsimile.
3-4. Loading the documents
1) Make sure that the documents
are of suitable size and thickness,
and free from creases, folds, curls, wet glue, wet ink, clips, staples
and pins.
2) Place documents face down in the hopper.
i)
Adjust the document guides to the document size.
ii) Align the top edge of documents
and gently place them into the
hopper. The first page under the stack will be taken up by the
feed roller to get ready for transmission.
NOTES:
1)
Curled edge of documents,
if any, must be straighten
out.
2)
Do not load the documents
of different
sizes and/or
thicknesses together.
