- Selector 4: Previous filtering parameters for white level compensation
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.
