xerography

Thân thiện

A technician uses xerography to make a copy of a document.

Definition

Noun: 1. A photocopying process: Xerography is a dry process for copying documents and images. It forms an image by using light to create an electrostatic charge pattern on a specially coated plate or drum. This latent (invisible) image is then developed using a powder (toner) that sticks only to the charged areas, and is finally transferred and fused onto paper.

Usage

• Xerography is the foundational technology used in most modern photocopiers and laser printers.
• The term is often used in technical, historical, or industrial contexts to describe the core copying process.

Examples

• The invention of xerography in the 20th century revolutionized office document reproduction.
• This printer uses xerography to produce sharp, dry copies almost instantly.
• Understanding the principles of xerography is important for technicians who repair copiers.

Advanced Usage

• Edge enhancement: This is a characteristic effect in xerography where the boundaries between dark and light areas are accentuated, making text and line art appear exceptionally sharp. This occurs because of the nature of the electrostatic discharge at edges.
  • The xerography process naturally provides edge enhancement, which is why text from a laser printer looks so crisp.

Variants and Related Words
