Electrophotographic process (EP process)

Printhead

The printhead scans the photo conductor drum surface with a laser beam. It consists of the following
components:

•

Laser diode (LD) card assembly

•

Oscillator

•

Start of scan card assembly

When a laser beam is scanned across the photoconductor drum surface from one end to the other while turning
on and off the beam, one line of latent image is created. If the scanning by the laser beam is repeated while
rotating the drum, a two-dimensional image is created. The resolution in the scanning direction (from right to
left) is determined by the rotational speed of the printhead motor, depending on how quickly the laser is
adjusted. The resolution in the process direction (from top to bottom) is determined by the rotational speed of
the printhead motor. The higher the scanning speed becomes, the sooner the scanning of the next row can be
started.
