If the Self-Test button pressed, vertical lines are printed.
Turn the power on while pressing this button, '89' shows in the DCU and the printer is warming up. After warming-
up the printer is in READY Mode, and '88' shows in the DCU. In this mode, without any detection, the printer begins
printing(trial printing and data from the PC). It is convenient to use this mode when the engine malfunction is
detected in the control board.
