3-A
Copy mode image density adjustment
NOTE: This adjustment sets the copy density for each mode.
<How to operate>
When this adjustment is executed, the warm-up and the shading is
performed. Then, the current setting value is displayed in 2-digits.
When the adjustment value is entered by the [Numeric] keys and
press the [START] key, the setting value is saved and the machine
makes one copy.
When the setting value is increased, the printing copy becomes
darker. When the setting value is decreased, the printing copy
becomes lighter.
With this adjustment, only the Exp3 copy can be printed. If the set-
ting value is increased, the Exp.1 and the Exp.5 copy also become
darker. If the setting value is decreased, the Exp.1 and the Exp.5
copy also become lighter.
When the [INTERRUPT] key is pressed, the process is interrupted
and the machine goes into the sub code input standby mode. When
the [CA] key is pressed, the simulation is terminated.
The switching of each setting and display can be made with press-
ing the [AUTO/TEXT/PHOTO] key. The adjustment range is from 1
to 99.
