Document Quality

This section describes the types and weights of paper that the scanner can read and precautions in
preparing documents to ensure maximal scanner functioning.

Document type

The recommended paper type for documents is as follows:

• Woodfree paper

• Plain paper (for example, the paper type specified for XEROX 4024)
When using any other type of paper, test feed a few sheets with the ADF to ensure the paper feeds

properly before performing a large-scale reading operation.
Any paper can be used on the flatbed. However, the ground color specification must satisfy the

specification described in the Grounding Color Area section.

Paper weight

The paper weight should fall within the following ranges:

• 52 to 127 g/m2 (13.9 to 34 lb), 127g/m2 (34lb) for A8
Precautions

A preliminary document feed test may be necessary to avoid unexpected errors. If document slip or jam
in the ADF (JAM error) or double feed occurs frequently, read the documents manually using the flatbed.
The following documents may be difficult to read properly using the ADF:

• Paper with clips or staples.

• Paper written on with wet ink.

• Paper without a constant thickness. (like envelopes)

• Paper with large rumples or curls. (See the NOTICE on the next page.)

• Paper with folds or tears.

• Tracing paper.

• Coated paper (for example, some paper used for color printing).

• Carbon paper.

• Paper smaller than A8 (Portrait) size, or larger than A3 or Double Letter.

• Materials other than paper (for example, clothes, metal foil, or OHP film).

• Photographic paper.

• Paper with notches on its side.

• Non-rectangular paper.

• Very thin paper.

4-2

NOTICES

1. When scanning a translucent document, set the density to light mode.

2. Carbonless papers have a chemical composition that damages the Pad and Pick roller. Therefore, note
the following:

Cleaning: If mispicks occur frequently, clean the Pad and Pick roller in accordance with

the “Cleaning and Maintenance” manual.

Replacement of parts: The life of the Pad and Pick roller may be shorter than if PPC paper

documents are fed.

3. The leading edge of all documents fed using the ADF should be straightened so the curl of the paper
meets the specifications shown below:

Less than

Double Feed Detection Condition

When the double-feed sensor is used, the thickness or the combination of the thickness and the length of
the document is subject to the following specifications:

1 Thickness: 0.065 mm to 0.15 mm
2 Paper length accuracy: 1% or less
3 Any black print at the center of the leading edge of the paper is not allowed. (10 mm x 10 mm)
4 No binding holes are allowed within 35 mm of the middle (halfway point) along the center of the paper.
5 Printing duty: 12 % or less
6 The deviation of the amount of transparent light on the base color area should be less than 10 %.

GLOSSARY OF TERMS

A4 size

A standard paper size. Paper size is 210 x 297 mm.

A5 size

A standard paper size. Paper size is 148 x 210 mm.

A6 size

A standard paper size. Paper size is 105 x 148 mm.

A7 size

A standard paper size. Paper size is 74 x 105 mm.

A8 size

A standard paper size. Paper size is 53 x 74 mm.

Abrasion counter

Counts the cumulative number of documents read to indicate when belts/rollers should be replaced. The
number of read documents accumulates until an operator resets the counter. The counter should be reset
when these consumables are replaced.

ASCII

The acronym for American Standard Code for Information Interchange.
ASCII is a set of 256 codes (numbered 0 to 255) used to communicate information between a computer
and another device such as a scanner.

Automatic separation

An image processing method in which the scanner automatically detects difference between text and
photos, and chooses the threshold accordingly. Automatic separation allows the scanner to switch
between line mode and half tone mode in one pass.

Automatic start mode (<-> manual start mode)

In this mode, the reading operation is activated only by issuing the the START command.

Backside reading = Back-side scanning

Refers to reading the backside of the document, specifically in Duplex reading mode.

Bit

The smallest unit of information in computer memory. A bit is a single digit, either a 1 or a 0, in the binary
numbering system. Eight bits equal one byte.

Density

In this manual, refers to a measurement of the depth of the display.

Dither

Technique for producing halftone images by representing the entire grayscale with only two pixel levels,
black and white.

GL-1

Double feed detection

A scanner function which detects the accidental feeding of multiple sheets by the ADF unit. Can be turned
on or off by the operator.

Double Letter Size

A standard paper size used in the U.S.A. and othe countries. Paper size is 11 x 17 inches.

dpi

Dots per inch.

Dropout color

A color which is used in the document but does not appear in the read image.

Duplex reading mode

A reading mode in which both sides of the document are read.

Equipment Error

An error that cannot be corrected by the operator. Call CE.

Error diffusion

High-quality halftone (pseudo-grayscale) image production based on black-and-white pixel binarization. A
pixel’s optical density and that of adjacent pixels are summed, with black pixels relocated in their order of
density as they relate to adjacent pixels.
The purpose of this technique is to minimize the average error between read and printed densities. Den­sity data for adjacent pixels is modified by diffusing errors on the objective pixel into several pixels, which
are then binarized. This maintains high grayscale levels and resolution during reading, while suppressing
more patterns by dotted halftone images such as newspaper photographs.

FB

In this manual, FB means flat bed.

Filtering

A correction method that improves the read quality of handwritten documents. The read quality of images
written in pencil or ball-pointed pen depends on the reflective light characteristics of the specific ink or
lead used. Dropped pixels may produce outlines, gaps, or thin, barely connected lines due to uneven
optical density. Filtering detects areas lighter than their surroundings and increases their density to
improve image clarity.

Front-side reading = Front-side scanning

Refers to reading the front side of the document, specifically in Duplex reading mode.

Halftone processing

Any method used to reproduce a photograph which includes a shade as an image composed of dots,
namely, a binary image. Dithering and error diffusion processing are examples of halftone processing.

GL-2

Hexadecimal

A base-16 numbering system (also commonly referred to as hex numbers). Since a base-16 system
requires 16 digits, numbers 0 through 9 and letters A through F are used. It is convenient to express
binary numbers in hexadecimal because fewer digits are required.

Image emphasis

Density is decreased for lighter but not completely white areas adjacent to black areas. Weakening this
emphasis eliminates spot noise or produces softened images.

Image processing

An image is read with specified parameters.

Interface

The connection that allows communication from one part of a system to another. For example, electrical
signals are transferred between the computer and scanner over an interface cable.

Inversion (Reverse-image reading)

In reverse-image reading, data is changed from black to white and vice versa.

IPC preset mode

While reading binary images, it is necessary to set the scanner according to the quality of the sheet to be
read. In this mode, these settings can be performed in advance by corresponding each setting to a
pattern number.

IPC-4D

Image processing option of this scanner.

IRAS

Initialization of the hardware.

Landscape orientation

A document is transported and read with the long side vertical to the moving direction.

Letter size

A standard paper size used in the U.S.A. and other countries. Paper size is 8-1/2 x 11 inches.

Linedrawing mode

Selecting linedrawing mode makes threshold and contrast settings effective but prevents brightness from
being set. The specified threshold value determines whether black or white pixels are scanned. Line
drawing mode is therefore appropriate for scanning text and line art images.

Manual Feed mode = Manual Mode

Requires the operator to feed each document manually into the ADF paper chute.

Manual start mode (<-> automatic start mode)

The reading operation is activated by pressing the START button in this mode. Available only when video
option board is installed.

GL-3

Mirror image

The read image is symmetrically flipped to produce a mirror image of the original detected in the main
scanning direction.

Noise removal

Isolated noise from an image appearing as black spots in white areas and voids in black areas is removed
to improve image quality.

Operator panel

A panel containing the scanner indicators and buttons. The operator panel is used to control scanner
operations such as loading document, selecting features, and changing setup options.

Outline extraction

The boundary between black and white areas is traced and the outline extracted for closed areas.

PAPER JAM

A warning informing the user that document is jammed in the transport unit, or that transportation is
disabled because the transport unit is slippery. This warning also appears when a double feed is de­tected.

Photograph mode (White level follower OFF)

Selecting photograph mode makes brightness and contrast settings effective but prevents the threshold
from being set. With photograph mode, the darkness of image corresponds to the black-pixel density,
making it suitable in scanning images such as photographs having gradations.

Photo mode = photograph mode

A photograph is read properly in this mode.

Pick start time

The period from the manual insertion of the document until picking starts after the document passes the
hopper empty sensor.

Portrait orientation

A document is transported and read with the long side parallel to the moving direction.

Paper counter

Indicates the total number of read document from start of reading until the hopper becomes empty.

Read operation

Refers to the reading operation including Simplex reading and Duplex reading.

RS-232C interface

A type of serial interface. See Serial interface.

SCSI-ID

Used to specify a particular SCSI device when the initiator selects a target or the target reconnects to the
initiator.

GL-4

Serial interface

A standard computer interface. Information is transferred between devices over a single wire (although
other wires are used for control).
With a serial interface, an interface cable greater than 3 meters (10 feet) can be used. This is often
necessary in networking environments, where the scanner may be shared.

SETUP mode

In this mode, users can view or set a variety of function in off-line.

Simplex reading mode

Only the front side of the document is read in this mode. Place the documents face up at the center of the
hopper table.

Smoothing

A process that eliminates “jaggies” from slanted lines and curves. Irregular convexities are deleted and
irregular concavities filled in. This is useful in OCR applications, for example.

Temporary Error

An error correctable by the operator.

T erminator

Devices with a SCSI interface can be daisy-chained. A resistor that includes terminal circuits needs to be
placed at both ends of a cable when devices are daisy-chained. If a device (such as a scanner) is the last
device in a chain, leaving an interface connector unused, a Terminator theerfore must be attached to
provide those terminal circits.

Third Party Interface

Optional board provided by Fujitsu or interface board provided by a third party can be installed and used.

Time-out limit

This is the time the scanner waits for next document insertion after the last document feeding. The
scanner returns Paper Empty when no document is set after time-out limit.

TPS

Third Party Slot.
