3.7 – Printers: Laser Printers

The process of rendering the entire printed page in the memory of the laser printer.

Applying a negative charge to the photosensitive drum, preparing it for image projection.

Using a laser to project the image onto the photosensitive drum.

Transferring toner from the cartridge to the photosensitive drum, sticking to the areas exposed by the laser.

Transferring the toner from the photosensitive drum to the paper

The photosensitive drum inside a laser printer that picks up toner and transfers it to the paper, creating the image.

A critical component of a laser printer that permanently affixes toner to the paper using heat and pressure.

A component in a laser printer that carries toner from the imaging drum to the paper, allowing for efficient transfer of multiple colors in color laser printers.

The process of permanently fusing toner to the paper in a laser printer by using heat and pressure.

Powdered ink used in laser printers, mixed with high voltages, heat, and pressure to create a printed image.

The color that is written or drawn by the laser on the imaging drum, corresponding to the image that will be printed.

A component in a laser printer that writes or paints the image onto the imaging drum, determining what will be printed.

A printing technology that uses a laser beam to transfer toner onto the paper, creating high-quality prints at a fast rate.

Cyan, yellow, magenta, and black are the four standard colors used in most laser printers.

The toner cartridges in a laser printer are typically housed as individual units, allowing for easy replacement and flexibility in color usage.

The belt serves as a temporary storage for the toner from each cartridge before it gets transferred to the paper.

The transfer roller is responsible for transferring the toner from the belt onto the paper.

The pickup roller grabs a single sheet of paper from the tray and feeds it into the printer for printing.

The separation pad helps the pickup roller to pick up only one sheet of paper at a time and prevents multiple sheets from being fed at once.

Duplexing refers to the ability of a printer to print on both sides of a sheet of paper automatically.

A duplexing assembly is a mechanism built into a printer that flips the paper over to allow for printing on both sides.

The processing phase in laser printing involves receiving and processing the data to be printed before any physical printing begins.

The charging phase involves applying a negative charge to the photosensitive drum to prepare it for receiving the image.

The exposing phase involves the laser beam writing the image onto the photosensitive drum by creating positive charges where the laser hits.

In the developing phase, negatively charged toner particles from the cartridge stick to the positively charged image areas on the photosensitive drum.

The transferring phase involves transferring the toner image from the photosensitive drum onto the paper that passes through the printer.

The fusing phase involves applying heat and pressure to melt and permanently attach the toner to the paper.
