Scanner

Scanner lamp

The light source is an LED.

The LED emits little heat (low power consumption) and has excellent light output rise characteristics.

Sensor

The sensor collects the light that was reflected from the original and converts it to three color digital signals (R, G, B).

The resolution of this CMOS sensor is 600dpi.

Reflection plate (reflector)

The reflection plate reflects light from the scanner lamp and collects light to the reading point on a document. The light which illuminates the document is adjusted to be the same on the left and right so as not to cast any shadow on the document.

White reference seal

A white reference seal for shading correction is affixed to the underside of the scale on the left of the scanner unit. This is read by the scanner and CMOS when the power is ON. The data read is temporarily stored in a RAM, and used for correction of document image data.
