When performing the head angular adjustment, select “Move the carriage to the head angular adjustment position” so that the carriage moves to the center of the printable area. This enables the adjustment lever to move easily. However, since the head nozzle may dry out, move it within 5 seconds.

In order to make the carriage return to the home position, select “Return the carriage to the home position” and press Return key.

Press “Enter” key. Then, the printer will perform the head cleanimg automatically, and come back to adjustable conditoin. It takes about 90seconds for the head cleaning.
