Operation

Operation/
Procedure

Set the copy magnification ratio to any desired level and press the start button. The scanner scans (reads) once
at the scanning speed corresponding to the set copy magnification ratio. 
At that time, the operation of the scanner home position sensor (MHPS) can be checked wit the photoconductor
lamp. 
When the scanner is at the home position, that is, when the scanner home position sensor (MHPS) detects the
scanner, the photoconductor lamp lights up.
