If the Positions of Dots Shift...
When the thickness of the media, the height of the head, or the type of the ink used is changed, follow the
steps below and adjust the ink drop position for Bi-directional (Bi) printing to print properly.
Example of Pattern printing
1
Set a media, and then set the printing origin. ( P.2-6)

pressing the keys.
• Correction value : -40 to 40
• Check the test pattern. A correction value is at the position where an outward way and a
return way are on one line.
• If the correction value is not between -40 and 40, adjust the height of head then redo the
operations from the step 2.
5
Press the key.
