<Display item and content of each item>
* When the display item is not executed yet, “–––” is displayed. In case of an error, “ERR” is displayed.
* An error display is not made for the reference value and the correction value, and the previous value is displayed.

Purpose Setting
Function (Purpose) (This function is not used. Do not operate.)
Used to perform the forcible execution of 1
pixel half tone correction.

Item Operation
Operation/Procedure
1) When the machine enters Simulation 44-56, the following
screen is displayed.
When [EXECUTE] button is pressed, the forcible execution of
1 pixel process control is started. (When [EXECUTE] button is
pressed during execution, the operation is interrupted.)
* In case of a sensor adjustment error, press [EXECUTE] but-
ton to resume the operation.
2) The display shifts to the normal completion screen or the error
screen automatically.
When [RESULT] button is pressed, the result screen is dis-
played.
* Select a color with [K] [C] [M] [Y] buttons. The data of the
selected color are displayed.
Only one color button can be selected. The selected button
is highlighted. (In the initial screen, black ([K]) is selected.)
* When [EXECUTE] button is pressed, the 1 pixel process
control correction value setting is performed again.

Purpose Data clear
Function (Purpose) (This function is not used. Do not operate.)
Used to clear the correction value of 1 pixel
half tone correction.
Section Process
Item Data clear
Operation/Procedure
1) Press [EXECUTE] button.
[EXECUTE] button is highlighted, and [YES] and [NO] buttons
becomes active display.
2) Press [YES] button.
* The half tone correction value is cleared. [YES] button is
highlighted.
* When [NO] button or [EXECUTE] button is pressed, [EXE-
CUTE] button returns to the normal display, and [YES] and
[NO] buttons gray out.
* After completion of clearing the half tone correction value,
[EXECUTE] button returns to the normal display, and [YES]
and [NO] buttons gray out.
* The cleared data are saved to EEPROM and RAM.
