Comparison of LED and Laser methods
LED print head
Feature of LED print-head
- It is the solid light source, which is constructed by several thousands of independent luminescence parts, and by which the light scanning is electronized.
- It is a simple optical system and its light-path length is short, and the head capacity is small.
The best light source for tandem-type color printers.
Laser scanner
Feature of Laser scanner
- It is the scanning-type light source, which is constructed by a Laser Diode, and by which the light scanning is mechanical.
- It is a complex optical system and its light-path length is long, and the head capacity is large.
