Fujitsu M3099GX Front-side reading = Front-side scanning, Halftone processing, Heater control

Front-side reading = Front-side scanning

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

Halftone processing

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 the halftone processing.

Heater control

The heater is set to ON or OFF to keep the lamp at a constant temperature and stabilize the intensity of the lamp.

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.

Initial screen

A screen displayed when the power is turned on or when reading is activated by the command from the host computer.

INK EMPTY

A warning issued when the number of dots printed by the print head exceeds a specified value. It indicates that the life of the print head is near to the end and the replacement of the print head is soon necessary.

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.
