Endorser

The unit for printing characters before or after scanning. These characters may be used for collation of the documents and the image data. (See Appendix A)

Equipment error

An error which the operator can not recover, such as optical system alarm, temperature alarm and so on. It is necessary to make contact manufacturer's authorized service center for paper repair service.

Error diffusion

High-quality halftone (pseudo-grayscale) image production base 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 readed and printed densities. Density data for adjacent pixels is modified by diffusing errors on the objective pixel into several pixels, which are than binarized. This maintains high grayscale levels and resolution during reading, while suppressing moire patterns by dotted halftone images such as newspaper photo graphs.

Filtering

The quality of images written in pencil or ballpoint pen and readed depends on the reflective light characteristics of the ink or lead. Dropped pixel's may produce out lines, gaps, or thin, barely connected lines due to even optical density. Filtering detects areas lighter than their surroundings and increases their density to improve image clarity.

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.
