Find Cheap and Best Copy Machine

A copy machine is an electronic duplicator that fuses a reproduced image to plain bond paper. Photocopying is a process which makes paper copies of documents and other visual images quickly and cheaply. Most current photocopiers use a technology called xerography, a dry process using heat. (Copiers can also use other output technologies such as ink jet, but xerography is standard for office copying.)

Photocopying is widely used in business, education, and government. There have been many predictions that photocopiers will eventually become moot as information workers continue to increase their digital document creation and distribution, and rely less on distributing actual pieces of paper. However, photocopiers are undeniably more convenient than computers for the very common task of creating a copy of a humble piece of paper.

Function:

Most photocopy machines work as follows:

A copier drum is given a positive charge.

The image from the original copy illuminates the charged drum and a latent image is formed.

Static electricity attracts toner to the drum surface and a visible image is formed.

Toner on the drum is transferred to paper by positive charging.

After the image transfer process is completed, the paper is separated from the drum surface.

Toner on the copy paper is firmly fixed when the paper runs between heat and pressure rollers.

A cleaning blade wipes off excess toner.

Features:

Photocopying is now widely available and is a fairly economical way to print a small number of books.

There are many kinds of photocopy machines available. They might have the following features:

Enlarging and reducing images

Copying in color

Making overhead transparencies

Collating

Stapling

Gluing

Among the key advantages of photocopiers over earlier copying technologies (some gradually adopted) are:

Their ability to use plain (untreated) office paper.

Duplex or two-sided printing.

The ability to sort and/or staple output.

Digital technology: With digital copying, the copier effectively consists of an integrated scanner and laser printer. This design has several advantages, such as automatic image quality enhancement and the ability to build jobs or scan page images independently of the process of printing them. The biggest advantage of digital copiers is automatic digital collation. If you are copying a set of twenty ordered pages twenty times, for example, a digital copier needs to scan in each page one time only, then use the digital information to produce twenty sets.

The Blue Print process, another method of plan copying, has been largely superseded by whiteprints, which are of better quality and cost approximately the same.
