7.Press one of the following keys:

[SPACE]

Retry the operation.

[0]Quit the menu and return to the Adjustment and Check menu.

[RETURN]

WORK POINT

￿Adjusted values are not stored in the EEPROM until the printer is turned off. Therefore be sure to turn off the printer once after the adjustment program is executed.

￿The set values are transferred to the printer when this operation is executed. Therefore do not turn off the printer before exiting “VH, EEPROM”.
