What is the Photo Conductor Unit.

Photo Conductor Unit (PCU) is vital party in a number of imaging and printing devices, such as laser printers and copiers. The principle of photoconductivity is used in this unit so that by creating images in response to light, images are created. The PCU also has an electrostatic charge, and when light is shone through it there, it pulls in toner particles which create images on paper. The Photo Conductor Unit is around imaging technologies and makes sure printouts are sharp, clear and precise.


Photo Conductor Units in Imaging and Printing – Importance.

In delivering high quality print and image output Photo Conductor Units are vital. In devices used with regular high volume, office printers & copiers for example, they have a key role and are important for achieving consistent and accurate results. That is why PCU is critical technology across the print and imaging industry, the PCU directly affects print quality, energy efficiency and the lifespan of printing device.

How the Photo Conductor Unit Works

Photoconductivity: The Science Behind It

Some materials exhibit the property of being photoconductors: their electrical conductivity increases in response to light. Photoconductive material holds an electrostatic charge in darkness in a Photo Conductor Unit. When laser light or LED light strike the PCU only in certain areas, those areas are depleted of charges and form a latent image which attracts toner particles to those areas.


Key Components of a Photo Conductor Unit.

A typical Photo Conductor Unit consists of:


  • Photoconductive Drum or Belt: Electrostatic charge holding component.
  • Charge Roller: Before each cycle, charges the drum or belt.
  • Exposure System: The latent image is created when light is directed onto the photoconductive drum.
  • Developer Unit: The drum from which the image is produced receives supplies toner.

Step-by-Step Process: How Images are Formed

  • Charging: The photoconductive drum is electrostatically charged by the charge roller in a uniform condition.
  • Exposure: Latent image is formed on the drum, where areas are selectively discharged by light from a laser or LED.
  • Development: The discharged areas attract Toner particles which result in visible an image on the drum.
  • Transfer: Paper absorbs that toner image and transfers it.
  • Fusing: The toner is then heated and pressure fuses to the paper to complete the image.

Photo Conductor Units Types

Organic Photo Conductors (OPC's)

Organic Photo Conductors (OPCs) are made from organic (i.e., not metal) compounds. OPCs are well known for the materials used in them and for their cost effectiveness, and are often used in manufactures standard laser printers and copiers. Do have a shorter lifespan than their inorganic counterparts, but are excellent every day printing needs.


Inorganic Photo Conductors

Metal and metal oxide based inorganic Photoconductors tend to provide higher resistance to environmental factors, as well as longer durability, though they are usually made of metal or metal oxides. For high end applications with high performance requirements in commercial and industrial environments, these units are perfect.


Amorphous Silicon (a-Si) Photo Conductors

Amorphous Silicon (a-Si) Photo Conductors are made from non-crystalline silicon with high stability and longevity. Usually, such technologies are used in habitats that require high-volume, high excitation and high precision conditions due to their ability to resist such conditions.

The Applications of Photo Conductor Units in Many Industries
