Study Notes
- A laser printer is a popular printer type, known for its high-quality output and fast printing speeds.
- The printing process involves an imaging drum, which picks up toner and transfers it to the paper, and a fuser assembly, which permanently fuses the toner to the page.
- The imaging drum can be a separate component or integrated into the toner cartridge.
- Color laser printers use a transfer belt and roller to combine colors from separate cartridges onto a single page.
- The printing process begins with data processing, followed by charging the imaging drum, exposing it with a laser, developing the image with toner, transferring the toner to the paper, fusing it to the page, and cleaning the imaging drum.
- Some printers are capable of duplex printing, which prints on both sides of a page.
- The entire printing process involves seven distinct steps: processing, charging, exposing, developing, transferring, fusing, and cleaning.
Test your knowledge on the hardware components required for duplex printing in a printer. Learn about the mechanisms and assemblies needed to enable double-sided printing functionality.
