This allows you to check the operation of the Cutter Solenoid, Pump motor, Regulator
Solenoid, and Pressure motor. When you return to the menu screen after the checking

Edge Sensor Level Measurement
Measures the platen level (reflecting amount) detected by the paper edge sensor. When
paper is on the rear sensor, the sensor detects the paper width and obtains information
for each paper type. If paper is not on the rear sensor, the sensor obtains information for
each paper type at previous paper width detection.
Panel operations are disabled during executing the measurement. The measured result
is displayed as shown in the table below.
The platen level measurement is conducted from the home side to the anti-home side.
When it is completed, the Carriage moves to the position where the highest level
(reflection) is detected and stops there for three seconds.
Automatic Gap Adjustment
Makes Uni-D and Bi-D (PG 1.6mm/PG 0.8mm) adjustments.
This function automatically prints adjustment patterns in Uni-D and Bi-D, and detects
the highest density point on the printed patterns to automatically reflects the Uni-D and
Bi-D correction values.
The correction value for the Bi-D (PG 0.8 mm) is copied for the Bi-D (PG 1.2 mm) and
the Bi-D (PG 1.6mm) correction value is copied for the Bi-D (PG 2.1mm/PG2.6mm)
