Study Notes
-
The fuser assembly in a laser printer uses heat and pressure to melt and permanently affix toner to the paper.
-
The fuser assembly consists of a dark brown drum that allows for the application of heat and pressure.
-
Color laser printers use a transfer belt and roller to combine and transfer toner from individual cartridges onto a single page.
-
A pickup roller in a laser printer is responsible for picking up and sending one page at a time through the printing process.
-
The pickup roller and separation pad work together to pull the top page off the printer tray and send it through the printer.
-
Duplexing is the capability of a printer to print on both sides of a page, achieved through hardware inside the printer or as an optional add-on.
-
The printing process in a laser printer consists of seven steps: processing, charging, exposing, developing, transferring, fixing, and cleaning.
-
In the processing step, data is sent to the printer, and the image is rendered in memory before printing begins.
-
In the charging step, the photosensitive drum is cleared and prepared for the image to be written by the laser.
-
In the exposing step, the laser writes the image onto the photosensitive drum.
-
In the developing step, toner is attracted to the areas of the drum where the image has been exposed.
-
In the transferring step, the toner is transferred to the paper.
-
In the fixing step, heat and pressure are used to permanently affix the toner to the paper.
-
The printing process concludes with the cleaning step, where the drum is cleaned and prepared for the next printing cycle.
