USB Cable, USB/SD Card Slots
A USB cable [1] is permanently attached to the back of the operation panel.
The end of this USB cable is plugged into the USB Host slot of the machine
controller on the right side of the machine.
Two slots are provided to input scanned documents, an SD card slot [2] and a USB
memory device slot [3].
These slots are used for the scan-to-media and media-to-print features.
Scan-to-media: Scanned documents can be stored on memory devices inserted into
the side of the operation panel.
Media-to-print: The user can print documents that are stored on memory devices
inserted into the side of the operation panel.

Scanner Unit Cover
The scanner unit opens easily for removal of paper jams
(1).
It can also be opened to the full vertical position (2) for
servicing
This requires disconnection of the arms on the left and
right.

Original Table
The plates on the original table of the scanner unit can be
adjusted to accept originals up to 914.4 mm (36 in.) for
scanning.
Original length is limited to 15 m (49 ft.)
The SMC list from the factory is attached under the right hand side of the original

Front Cover - 1
The front cover can be easily raised to expose the platen for
cleaning and jam removal.
The front cover locks in place and remains open after it has been
raised, as shown on the left.
Two sensors (micro-switches) on each end of the front cover
detect when the cover is opened and closed.
To open the front cover, lift it and then fold the bottom into the
machine so that it locks and remains open, as shown on the right.
Do not open during operation, or copying/printing will stop.

Slide 18
Front Cover - 2
The front cover can be raised to remove paper jams and to load paper for bypass
feeding.
The left and right front cover switches (push switches) detect when the front cover is
raised and lowered.
The guide pins on either end of the front cover are set in tracks which guide the
cover into the correct closed position.
The front cover track switch (a push-switch) ensures that the carriage does not stop
suddenly, which could damage it (see the next slide for details).
The machine cannot operate until the front cover is down and all three of these
switches are closed.

Front Cover - 3
If the front cover is opened during copying, the front cover track switch
opens first. When the machine detects this, the carriage slows down.
Then, when the left and right cover switches open, the carriage stops.
This mechanism ensures that the carriage will not stop suddenly if the
cover is opened.
The carriage will not start again until the track switch closes again.

Front Cover - 4
Front cover track switch: When the pin on the left of the
front cover is inserted correctly into its track [A], it slides
down and pushes a micro-switch [B] to the rear. This
signals that the front cover is installed correctly.
If the switch stays open when the front cover is down, this
indicates that the cover is not correctly set in the track.
