Whenever you send a job to the
printer, an “image” of the page to
be printed is temporarily written to
the rotating surface of an
electrophotographic (EP) drum.
This image acts like a magnet that
attracts toner to the drum. (The
toner and the drum are both located
in the toner cartridge.)
At the same time, the paper (or
transparency film or envelope)
passes through the printer and is
electrostatically charged as it
reaches the drum. The toner that
was previously attracted to the
drum as an image is transferred to
the charged paper. The paper then
passes between two rollers where a
combination of heat and pressure
bonds the toner to the paper. The
paper is then moved to the output
tray.
