2) Close the front cabinet.
3) Select a developing unit to be adjusted.
4) When [EXECUTE] key is press
ed, it is highlighted. The DV
roller rotates, and the toner density sensor detects toner den-
sity, and the output value is displayed.
The above operation is executed for 1.5 minutes, and the aver-
age value of the toner density  sensor detection level is set
(saved) as the reference toner density control value.
When the reference toner density control...
