(Refer to Fugure 2-3.2 Carriage Moving Mechanism Operation The image data of a document are scanned in the combination of the main scanning direction (one line: CCD Sensor) and sub scanning direction (multiple lines: Carriage Unit movement).) The Carriage Unit slides along the guide rail in the sub scanning direction. A stepping motor used as the CR Motor is driven under open loop control.) The line type color CCD Sensor can only scan the data of one line in the main scanning direction (in parallel with the Carriage Unit) at one time. the Carriage Unit having a built-in CCD Sensor is moved by CR drive. The image data scanning start position is determined by the CR HP Sensor located on the Control Board. the CR (Carriage) Motor transmits its drive power to the Timing Belt. Carriage Operation Figure 2-3. To perform this sliding operation. (Refer to Fugure 2-5.EPSON Perfection V500 Photo Revision A 2.
