Notes:
• The setting value must increase as the LED emission level number (0 to 4) becomes higher. Do
not increase this order when setting the values.
• Usually, LED emission level 4 / 4 is most effective in the black mode.

Level 3/4: 191, Level 4/4: 255)

The smaller the value is, the toner amount adhered
decreases of the high density area (ex. prevention of
fusing offsetting, jam in the fuser unit, etc.).
Acceptable values: 0 to 255
