Once the image is transferred, the media travels to the fuser (D), the fuser exit rolls (E), and then to the output bin.

Electrophotographic process (EP process)
The method that all laser and LED printers use to print is called the electrophotographic process. These machines use
differences in charge to manipulate and move toner from the print cartridge to the printed page.
Even though the basic EP Process is the same for every laser and LED printer, the specifics for each printer are different.
Electrophotographic process basics
This printer is a single-laser printer that use four print cartridges (cyan, yellow, magenta, and black) to create text and
images on paper.
The printer has four photoconductors (sometimes called a photodeveloper cartridge or PC unit) built into the print
cartridges and an image transfer unit (ITU). Each color toner is painted to its respective photoconductor at the same
time. The transfer belt passes under the four photoconductors and the four-color image is produced and transferred
to the paper in one pass.
