EPSON Perfection 610 | Rev. B |
2.1 Engine Mechanism
This section explains the engine functions and operating principles of the EPSON Perfection 610. The engine mechanism has the two major parts; the carriage unit (=scanning head) and the carriage move mechanism.
2.1.1 Carriage Unit
The carriage unit is composed of the following:
CCD sensor board (containing the CCD sensor)
Inverter board
Lamp (the light source) Mirror and lens mechanism
Rear
Lamp
CCD Sensor Board

CCD Sensor Board
This board includes the Color CCD line sensor (independent R,G,B) and the sensor’s control and driver circuits.
Inverter Board
This board generates voltage used to drive the lamp. The board pressures up +24VDC and converts it from direct current to alternating current.
Lamp
A white cold fluorescent lamp is used as the light source.
Mirror and Lens Mechanism
Light emitted to the document reaches the CCD sensor via the mirror and lens mechanism in the carriage unit, where the light’s optical axis is corrected. Note other scanners separates R/G/B components by switching the light source between R, G, and B. In this scanner, however, it is performed by the CCD sensor itself.
