OVERVIEW
This chapter provides scanner features, configuration, and operation.
The M3099GX/GH 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 M3099GH and M3099GX are shown in Table 1.1
and 1.2. Those types of the scanner is hereinafter referred to as “this
scanner”.

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 M3099GH.
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).

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.
Figure 1.3 shows scanner configuration.

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.
M3099GX/GH 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
SCSI-2 interface
SCSI (small computer system interface) circuit consists of SPC
(MB86601A), VCEP (OTI95C71/20) and a glue ASIC. The scanned
image data are transferred to interface circuit as video interface. The
interface circuit converts internal video interface to SCSI interface via
compression, if required. SCSI interface transferes data 1.5MB/s in
Asynchronous transfer, 4.0MB/s in Synchronous transfer following to
SCSI-2 standard. The VCEP compresses the binary image data in
MH, MR, MMR algorithm defined by CCITT G3, G4. See Chapter
3 for details of SCSI interface.
Resolution
OVERVIEW
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.
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.
M3099GX/GH OEM Manual 1-9
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
