• Selectors 1 and 2: Monitoring the PC ON/OFF state

For the related functions, refer to WSW36, selectors 2 and 3.

• Selector 3: Parallel port output pins kept at high level

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.
• 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 white 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" (Enable) will apply previously saved white level data instead of
new incorrect compensation.
• Selector 5: Prevention of ink splashing in ink near-empty state
Setting this selector to "0" (Enable) prevents ink splashing by decreasing the head drive
voltage when the "Ink near-empty state" is detected.
(Monitor of power ON/OFF state and parallel port kept at high)
