2.1 Engine Operation Outline

This section explains the functions and operating principles of the 

EPSON Perfection V700 Photo Scanner. This model has two scanning 

engines, the Photo scanner in the unit base and the TPU scanner in the 

lid, each consisting of a Carriage Unit and a Carriage Mechanism.

2.1.1  Carriage Unit

The Carriage Unit consists of the ISN Board, Inverter Board, Lamps 

(light source), Mirror/Lens Mechanism, Glass Plate, and Solenoid. 

See Figure 2-1

, and 

Figure 2-2

.

Figure 2-1.  Carriage Unit Configuration

ISN Board

 contains the alternating six-line color CCD (R, G, B 

independent) sensor, and its control and drive circuits.

Inverter Board

 converts DC to AC and boosts the voltage to generate 

the current necessary to power the Lamps. 

Lamps

 used as the primary light source are white cool-cathode 

fluorescent lamps. If the light output becomes unstable, the Panel LED 

flashes and the scanner enters standby mode until it becomes stable.

Mirror/Lens mechanism. 

The lamp light reflected off the scanned 

document passes through the Mirror/Lens mechanism in the Carriage 

Unit for correction of the beam axis before it reaches the CCD Sensor. 

The R, G, and B light components are extracted by the processing 

capabilities of the Color CCD Sensor itself, not by switching between 

the R, G and B of the light source as in other models.

Glass Plate

 compensates for the wavelength difference between the 

infrared light and visible light when the Digital ICE function is used.

Solenoid

 moves the Glass Plate into or out of the beam path, as 

applicable.

lenses is automatically selected.
