3.4.7 Gamma balance adjustment
The density is adjusted by adjusting the gamma balance. The adjustment is performed by selecting its
density area from the following: low density, medium density and high density.
< Adjustment Mode (05) >
Note:
Changing the adjustment setting influences the adjacent density area slightly.
E.g.: When the value of the medium density is larger, the adjacent areas in the low density and
high density range will become slightly darker.
<Procedure>
(1) While pressing [0] and [5] simultaneously, turn the power ON.
(2) Key in the code for an item to be adjusted and then press the [START] button.
(3) Key in a number for the density area to be adjusted (0, 1 or 2), and then press the [START]
button.
0: Low density 1: Medium density 2: High density
(4) Key in an adjustment value.
(To correct the keyed-in value, press the [CLEAR] button.)
(5) Press the [ENTER] or [INTERRUPT] button to store the value in memory. The equipment goes
back to the ready state.
