Correct the ink drop position for bidirectional printing

When the condition for printing (media thickness/head height/etc.) has been changed, perform the following operation to correct the ink drop position for bidirectional (Bi) printing and obtain the proper printing result.

Example of a Drop Position correct Printed Pattern

• The correction pattern for aligning the ink drop position cannot be printed on a media whose width is less than 450 mm. Print quality cannot be guaranteed in such a case. Use unidirectional printing.

The dots at the fourth position counted from the zero position in the positive direction form a straight line. In this case, the dot position correction value is 4.0.

•Corrected feeding rate: -40.0 to 40.0

•Open the front cover and check the test patterns. The position where an outward feeding line and a return feeding line become one straight line is the correction value.

•When the correction value in not between -40.0 and 40.0, adjust the height of the printing heads and then perform the operations in Step 2 and later.
