Purpose Operation test/check
Function
(Purpose)
Used to check the operation of the scanner (reading)
unit and its control circuit.
Section Optical (Image scanning)
Item 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.
