46 02 Copy density adjustment
(600dpi)
[Function]
Copy density is set for each mode.
When this simulation is executed, the current se value is displayed in 2 digits (Default: 50).
Change the set value and press [START] key to make a copy under the set value.
When the set value is increased, the copy becomes darker. When the set value is decreased,
the copy becomes lighter.
In this case, only Exp.3 copy is made. When, however, the setting is made to make darker copy,
Exp.1 and Exp.5 copies also become darker. When made to lighter copy, Exp1. and Exp.5 cop-
ies become lighter, too.
Press [ ] [ ] key to switch the mode. The set value of the selected mode is displayed on

decreased, the contrast becomes lower.
In this case, only Exp.3 copy is made. When, however, the setting is made to make higher con-
trast, Exp.1 and Exp.5 copies also become in higher contrast. When made to a lower contrast,
Exp1. and Exp.5 copies become lower contrast, too.
