Scanner Types

OVERVIEW

This chapter provides scanner features, configuration, and operation.

The M3099EX/EH is a very fast and highly functional image
scanner developed for volume filing, using charge-coupled device
(CCD) image sensors. This scanner, featuring duplex reading and
high-quality image processing, read documents fed by an automatic
document feeder (ADF).

Scanner types of M3099EH and M3099EX are shown in Table 1.1
and 1.2. Those types of the scanner is hereinafter referred to as “this
scanner”.

OVERVIEW

Features

This scanner has the following features:

Duplex reading

Both sides of a document are read at the same time and their data
transferred serially.

Fast reading

This scanner can read documents at high speed: 80 sheets/min (A4,
200dpi) in the simplex reading mode and 60 sheets/min (A4,
200dpi) in the duplex reading mode by M3099EH.

Large-capacity hopper

Up to 1000 sheets (A4, 55 kg) can be loaded on the hopper by the
1000 sheets hopper type.

High-quality image

This scanner uses a compact optical system that provides sharper
focus. Furthermore, the use of new LSI chips produces finer images.

New image processing function

The error diffusion feature is provided as standard. Dithering or
error diffusion can be applied to those areas judged to be
photographs by automatic separation (image processing II option).

1-4 M3099EX/EH OEM Manual

Configuration

This section provides configuration and components of the scanner.

Configuration of the scanner

This scanner can be divided into two major sections, mechanism and
control unit.

The mechanism unit consists of a hopper to load documents,
automatic document feeder, upper and lower transport units to
transport documents, a motor drive system, and an optical unit.

The control unit consists of an operator panel, a power supply, a
mechanism driver to drive and control the mechanism unit, an image
processing control, and an interface control.

Operation Overview

This section outlines the operations of the mechanism and control
units of the scanner.

Operation of the mechanism unit

The mechanism unit consists of two optical units (front and back
sides), a hopper and ADF, upper and lower transport units, a motor
drive system, and a stacker. Each optical unit consists of a CCD
image sensor, a lens, and mirrors. The hopper and ADF feeds
stacked documents and the upper and lower transport units transport
the documents. The motor drive system drives these units. The
stacker stores documents.

When the power is turned on, the lamps are lit and the scanner
waits until the light intensities of the lamps become stable. Once the
light intensities have become stable, the scanner is ready for a
command from the host machine.

A document is picked from the hopper and then ADF feeds a
document one by one. The document width is checked and
document top is detected.

The documents are counted, fed, and stacked on the stacker.

OVERVIEW

The lamps illuminate the document, and a lens focuses the images
on CCD for photoelectric conversion processing.

M3099EX/EH OEM Manual 1-7

Operation of the control unit

The control unit consists of an operator panel, a power supply unit,
mechanism driver, an image processing control, and an interface
control.

This scanner has the following circuit configuration:

• Operator panel

• Control circuit (MPU)

• Video circuit (front-side/back-side)

• Interface circuit

• Duplex circuit (back-side)

• Motor driver circuit (including a stepper motor, a clutch driver)

• Power supply unit

• Image processing circuit (IPC II option)

• Memory board

Main control unit

This scanner is controlled by a 80C186 MPU. This scanner consists
of a ROM as a program area, internal registers, an external RAM as a
work area, gate arrays for the MPU peripheral and video circuits,

dither processing and γ conversion RAMs, and error diffusion.

Interface control

RS-232C and video interface

RS-232C interface

The RS-232C interface consists of an ACIA( 8251) and driver-receiver
ICs (145406).

Video interface

This scanner processes a document by the 256-step gray scale. Images
are processed in a way specified by the interface or the operator panel
and transferred serially in eight-bit units. Eight-bit data has V0 at the
left end and V7 at the right end and strobed by VCL.

HGATE ensures the validity of data in the main scanning and
VGATE for the subscanning.

OVERVIEW

The scanner status is basically reported by the RS-232C interface. An
equipment error is reported to the host computer by a FAIL signal in
case that RS-232C communication failed. See Chapter 3 for detailed
specifications of the interfaces.

Resolution

The basic resolution of this scanner is 200dpi. The resolution can be
changed to 240, 300, or 400dpi from the host computer or the
operator panel.

The resolution in the subscanning direction is achieved by changing
the document transport speed.

When the image processing circuit II (IPC II) option is installed, the
linear density is changed by setting the parameter to its internal circuit.

M3099EX/EH OEM Manual 1-9

Video amplifier and driver section

This section consists of a CCD drive circuit, a video amplifier
circuit, a white-black level correction circuit, sensors, and also
control circuits for the stepping motor, heater, and lamps.

Image processing section

The IPC II option enables the following image processing functions:

• Automatic separation function (to read documents containing
characters and photographs)

• Inversion function

• Mirror image output function

• Outline extraction function

• Overlay function

• Smoothing, filtering, and noise removing

Power supplies

This scanner has two power supplies. Their output voltages are as
follows:

Power supply 1

• +5V: For logic circuits

• ±12V: For video amplifiers

Power supply 2

• 24V: For lamp, heater, and stepping motor drive

Scanning video data is transferred to the host computer trough video
data signal line V0 to V7 in parallel synchronized with VCL.

Transfer sequence

Scanning is performed as sown in Figure 3.3, and the scanning data
is assigned to the video data signal as shown in Figure 3.4. The
scanning data is sent to the host computer in order of scanning.

Notes:

1. Abnormal reception means that a parity error, framing
error, overrun error, or count error has occurred.

2. Command or response transmission is retried only twice.

3. Upon reception, a command or response is checked for
transmission errors. When the check result has no
problem, ACK is returned immediately to the originating
source. When the check result has problem, data other
than ACK is returned after all data has been received.

Response data

ACK
(Acknowledge)

Parity error

Framing error
Overrun error

Reception error

4. The originating source of the command/response
monitors the response from the receiving side. ACK
indicates that command/response transmission is
completed.

Details

A command or response has been
received without an error.

A parity error has been detected in
received data.

A framing error or an overrun error has
been detected in received data.

The byte count for the command or
response does not match the number of
bytes transferred.

Code (Hex)

X 'FF'

X'80'

X '81'

Reception error causes the command/response to be
transmitted again. The transmission is returned only
twice. After that, the scanner waits for a new command.

5. Response data such as ACK must be retried to the
originating source within 0.5 second.

6. The interval between words in the data stream must be no
more than 10 ms.

M3099EX/EH OEM Manual 3-15

Command/response format

The command/response format is as follows.

scanner status. The sense command can be issued at any time if
another command does not require the response from the scanner.

IMAGE MODE SENSE command

This command is valid for the scanner with the image processing
circuit. When the scanner receives this command, the scanner
reports the image processing mode of the main window and number
of pixels (Unit: Byte) per line in the X-direction. By specification
byte 3 of this command, the front or back-side image status can be
selected.

*1: Up to eight types, from #0 to #7, can be registered for dither

pattern or overlay pattern. When the power to the scanner is
turned off or when the scanner is reset, registration must be
done again. When a pattern is built in, registration need not be
done again.

Pattern data format

1 byte data corresponds to data for 1 dot.

• For dither pattern
X'00' to X'FF' should be sent as dither pattern.

• For overlay pattern
X'00' or X'FF' should be sent
When the data is X'FF', the data of the dot is changed to white.
When the data is X'00', the data of the dot is not changed.

Transfer the dither and overlay patterns in the order shown below.
