II. READING SYSTEM
1. Reading Unit
The sectional view of the reading units is
shown below. The upper and lower reading
units have the same configuration but the
different shapes for the reading cover each.
CIS unit
Reading
cover
Figure 2-201
The upper reading unit reads the back
side of the documents and the lower reading
unit reads the front side of the documents.
This configuration enables the machine to
read both front and back sides of a docu-
ment using a single scan. However, when a
card is scanned, the upper reading unit
reads the front side of the card and the lower
reading unit reads the back side of the card.
The read image data are sent to the
image processing section of the control
PCB.
The reading unit consists of CIS unit,
and reading cover.
The CIS unit consists of CIS PCB, lens
array, LED (R/G/B), light guide, and case.
The reading glass and white reference
sheet are mounted on the reading cover.
Photosensitive pixels are mounted on
the CIS PCB with a density of 600 dpi in a
line. The effective reading width is 216 mm,
and the number of effective picture elements
is 5104.
A set of three basic color LEDs, red,
green, and blue (RGB), is mounted only on
the one side. This single-side illumination
causes a shadow on a document, which
may effect on the image data quality.
In the binary or grayscale modes, image
data are read with composite light generated
by lighting the RGB LEDs at the same time.
In the color mode, the LED is successively lit,
and reads image data with each color. As
documents are being fed at regular speed
while image data are read, the reading po-
sitions of RGB are shifted slightly.
In the color dropout mode, only the LED
of a designated color lights. In the color
emphasis mode, the LED of a color other
than a designated color lights.

CHAPTER 2 FUNCTION & OPERATION
2. Shading
This section explains the reading
mechanism of the white reference sheet for
determination of the shading correction
value.
The sectional view of the reading unit is
shown below.
White
reference
sheet
White
reference
sheet
Figure 2-202
This machine can read the white refer-
ence data at the document reading position,
unlike other scanners having the black
background color, since its background color
is white. Therefore, there is neither need to
feed the shading sheet nor to move the
internal white reference sheet or the reading
units.
For example, when the lower reading
unit reads the white reference data, the LED
emitted from the lower unit is reflected from
the white reference sheet on the upper unit
to be input to the sensor on the CIS PCB.
Since the white reference sheet is
placed under the reading glass, feeding
document does not cause smudges on it.
When this machine is turned ON or
starts scanning, it reads the white reference
data to determine the shading correction
value.
However, the slightly different optical
paths to the light receiving element are used
for the actual document and the white ref-
erence sheet. Therefore this machine needs
fine adjustment of the shading correction
value using the service mode and the
shading sheet. This fine adjustment is nec-
essary after replacing the reading unit or
after replacing the control PCB recording the
shading correction value.

CHAPTER 2 FUNCTION & OPERATION
1) Feed path
The feed path of this machine is a straight
path that tilts from the pickup tray to the
registration roller and is horizontal to the
front roller including the reading section.
The pickup roller is not mounted.
The leading edge of the loaded document
touches the feed roller and the separation
pad. Once the machine starts scanning, it
activates the rollers to feed the document
inside. The document passes through the
registration roller, the reading units, and
the front roller and is ejected to the outside
of the machine. This machine does not
have an eject tray.
2) Drive
The feed motor drives the feed roller and
each drive roller. The rotational speed of
the feed motor is determined by scan
conditions.
To provide space between the leading
edge of a document and the trailing edge
of the next document, the drive speed of
the feed roller is slightly lower than the
drive speed of the registration roller and
front roller. If it is left as it is, the document
is braked when it touches the feed roller
and the registration roller, and therefore, a
one-way clutch is built into the gear used
in the feed roller drive system to follow the
drive speed of the registration roller.
3) Separation
Separation of the documents is performed
by the separation pad. Double feeds and
pickup errors are prevented by optimizing
the shape of the separation pad and fric-
tion against documents.
However, if the document setting method
is incorrect, the contact between the
document and the separation pad be-
comes poor and double feeds or pickup
errors tend to occur easily. For details on
the document setting method, refer to the
“User Manual” or "CHAPTER 1 GENERAL
DESCRIPTION, III. USER OPERATION".
4) Sensor
For document detection, the document
sensor is mounted on the document set-
ting section and the registration sensor is
mounted on the registration roller section.
They are used for feed control and feed
error detection

The sectional view of the card feed
system is shown below.

7 Upper reading unit (front reading)
{
8 Lower reading unit (back reading)
The basic functions of the card feed
system are the same as those of the
document feed system, but the card feed
system has a feed path dedicated to cards.
The feed path dedicated to cards is lo-
cated on the right side of the machine body,
and the insertion and eject openings of the
card feed path are located on the eject side
of the document feed path.
Figure 2-303
When a card is placed in the insertion
opening, the card sensor detects the card
and feeding begins. The feed motor runs
reversely at this time. The card is fed straight
and passes through the reading section.
Then, the rotation direction of the feed motor
is changed to normal direction, and the feed
direction of the card reverses. Like docu-
ment feeding, the card passes through the
reading unit and the front roller and is
ejected.
As only a single card is placed, no
separation mechanism is required. Like the
document feed system, the card feed sys-
tem has a registration sensor in the regis-
tration roller section to control the beginning
of scanning and detect feed errors.

CHAPTER 2 FUNCTION & OPERATION
3. Feed Error
‹ Paper Jam Detection
Paper jams are detected by the regis-
tration sensor. The types of the document
jams are described as follows.
1) Pickup Delay Jam (Pickup Error)
The leading edge of the document was not
detected by the registration sensor within
the specified time after the machine starts
scanning.
2) Early Reach Jam
The leading edge of the following docu-
ment was detected after the trailing edge
of the document was detected by the
registration sensor before the document
has been fed for a specified length.
3) Residual Jam
The trailing edge of the document was not
detected even though the document has
been fed for the maximum specified length
after the leading edge of the document
was detected by the registration sensor.
4) Fast Feed Jam
The trailing edge of the document was
detected after the leading edge of the
document was detected by the registration
sensor before the document has been fed
for the minimum specified length.
5) Non-removal Jam
The machine starts scanning while the
document is detected by the registration
sensor and still remains inside this ma-
chine.
‹ Double Feed Detection
A double feed is detected by the
document length detection by the registra-
tion sensor.
The first document length of the
scanned batch is used as a reference to
detect the document length. The 35 mm or
more difference from the standard is inter-
preted as a double feed.

CHAPTER 2 FUNCTION & OPERATION
Analog signals proportionate to the
density of each picture element are output to
the analog processor on the control PCB
from the CIS unit. The resolution of the
output data is either 300 dpi or 600 dpi ac-
cording to the user settings.
The analog processor carries out offset
adjustment, gain adjustment, and A/D con-
version. Analog signals are converted into
12bit digital signals in the analog processor.
Then the image data is transferred to the
scanner controller and converted from 12
bits to 8 bits.
After that, the image data is output to the
computer through USB interface. The USB
cable used for this machine is a special
cable with a USB3.0 standard A type con-
nector on the computer-side and a USB2.0
micro B type connector on the device side.
The signal speed supports USB2.0
Hi-speed.
The computer performs the image
processing according to the user settings
after the signal rearrangement, resolution
conversion and shading correction.
Since this machine has a white back-
ground, black border removal and punch
hole removal are not necessary.

CHAPTER 2 FUNCTION & OPERATION
V. POWER SUPPLY
1. Power Supply
USB bus power is used to supply power
to this machine. This is a method of sup-
plying power from the computer through a
USB cable.
The USB cable used for this machine is
a special cable and the signal speed sup-
ports USB2.0 Hi-speed, but the rated power
is different with the USB interface on the
computer side. The rated power of a USB2.0
cable is 5 VDC, 0.5 A, and the rated power
of a USB3.0 cable is 5 VDC, 0.9 A.
When a power supply cable is con-
nected and the pickup tray is opened, the
tray switch is pressed and the power is
switched ON. When the pickup tray is closed,
the power is switched OFF.
Each voltage required inside is gener-
ated on the control PCB.
The main parts that consume electricity
in this machine are the elements of the ICs,
etc. on the control PCB, the upper and lower
CIS units and the feed motor. The required
current value for the feed motor changes
according to the load during feeding. To use
a special method of feed motor control and
power supply if the load increases, the fol-
lowing components are provided:
1) Feed motor with an encoder
2) Electric double layer capacitor (EDLC)
3) Power supply USB cable
The encoder detects that the feed load
increases and the number of revolutions
decreases, the pulse supplied to the feed
motor changes. If the current is insufficient,
the capacitor is discharged. If the capacity of
the capacitor becomes insufficient, feeding
and reading stop and the capacitor is
charged. When it is charged again, the
feeding and reading begin. However, if the
prescribed rotational speed is not reached
even when an electric current is added from
the capacitor, the rotational speed is re-
duced and the timing of reading is changed
accordingly.
The reading cannot be started until the
electric double layer capacitor is sufficiently
charged. If the power is switched ON when
the capacitor is fully discharged, charging
takes approx. 15 seconds. Since it is dis-
charged when the power is OFF, reading
cannot be performed for a period of time of
approx. several to 15 seconds after the
power is switched ON.
The amount of power can be increased
by connecting the supplied power supply
USB cable between the computer and this
machine in addition to the ordinary USB
cable that is used for signal transmission
and power supply. If this cable is used,
power supply to the feed motor can be in-
creased, and therefore, temporary stop and
speed reduction can be prevented. The scan
speed when two USB2.0 cables are con-
nected is the same as that when one
USB3.0 cable is connected. Even if two
USB3.0 cables are connected, the scan
speed does not increase.

CHAPTER 2 FUNCTION & OPERATION
An AC adapter is provided as an option.
If the power supply USB cable cannot be
connected to the computer, the equivalent
DC power can be supplied to by connecting
the cable to the AC inlet and this machine.
