Selectors 1 and 2: Monitoring the PC ON/OFF state (Not used.)
For the related functions, refer to WSW36, selectors 2 and 3.
l
Selector 3:
Parallel port output pins kept at high level (Not used.)
Setting this selector to "0" will keep all parallel output pins of the machine at high level. Use this
setting if Resource Manager (bundled with MFC models) installed to WindowsNT running on the
connected PC fails to monitor the power ON/OFF state of the machine.
l
Selector 4:
Previous filtering parameters for white level compensation (Not used.)
At the start of scanning operation, the machine usually initializes white and black level data stored in
the EEPROM by scanning the while-level reference film attached to the inside of the scanner top
cover. After long use of the machine, however, the film may be contaminated with dust or dirt.
Accordingly, incorrect white level data will be set up so that white vertical streaks will be brought on
the scanning result.
Setting this selector to "0" (Enabled) will apply previously saved white level data instead of new
incorrect compensation.
