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
