Definition
A Digital Copier is an advanced office machine that employs digital scanning techniques for copying documents. Unlike traditional photocopiers, digital copiers can scan multiple pages swiftly, allowing users to retrieve the original documents immediately while the copies are being produced or stored in memory for later use.
How Digital Copiers Work
Digital copiers function by scanning the original document using a Charge-Coupled Device (CCD) sensor or Contact Image Sensor (CIS). The digital data collected is then processed and can be printed instantly or stored electronically.
Features of Digital Copiers
- Rapid Scanning and Copying: Users can scan multiple pages quickly, freeing up time to perform other tasks while copies are being made.
- Memory Storage: Documents can be stored digitally for later printing, reducing the need for immediate physical reproduction.
- Multipurpose Functionality: Beyond copying, digital copiers often serve as printers, fax machines, and scanners.
- Enhanced Output Options: The ability to print multiple pages on a single sheet, create booklets, and digitally edit damaged originals.
- Network Connectivity: Integrates with computer networks, allowing for seamless printing from desktop computers.
Historical Context of Digital Copiers
Digital copiers emerged as a technological evolution of traditional photocopying machines in the late 20th century, driven by advancements in digital technology and the growing need for efficient document management. Their development marked a significant shift towards multifunctional and interconnected office equipment.
Timeline:
- 1970s-1980s: Advent of digital scanning technology.
- 1990s: Introduction of digital copiers with memory and editing features.
