• Scanning of an original placed on the original glass
This motor drives the carriages-1 and -2 through the timing belt and carriage wire. First, the scan
motor drives the carriages-1 and -2 to their respective home positions. The home positions are
detected when the carriage-1 passes the carriage home position sensor (S7). When the [START]
button is pressed, the both carriages start to move and scan the original on the glass.
• Scanning of an original placed on the RADF
It stops at the scanning position and starts scanning, and performs shading correction before
scanning and at constant intervals during scanning.
• Scanning speed
The carriage speed of the original in the color scanning mode is half of that in the black and white
scanning mode.
