Explanation
Use this setting if you are unable to resolve banding (horizontal
striped lines or uneven colors) even after cleaning or aligning the
print head.
Pattern
O
This method allows you to correct by visually checking a
printed pattern and entering a correction value.
Check for the lightest colored pattern in lines A to D on the
printed adjustment pattern. In the following example, "3"
should be selected as it is the lightest.
1 2
A
Enter the confirmed number for each entry screen for lines
A to D.
Value
O
You can change the value based on the banding in the
printed material.
The correction value (-0.70 to + 0.70%) is set at a rate of one
meter per paper feed. Because a black band occurs (dark
colored stripe) if too little paper is fed, adjust it in a +
direction. Because a white band occurs (a white or light
colored stripes) if too much paper is fed, adjust it in a -
direction.
You can set the ink drying time for each print head pass. The
range is 0 to 10 seconds. Depending on the ink density or paper
type, the ink does not dry soon. In this case, set the drying time
longer.
You can set the suction pressure used to feed the printed paper.
When using a cloth or thin paper or when wrinkles appear in the
paper during printing, select HIGH or EXTRA HIGH.
You can select whether to perform this operation to reduce the
paper skew or not.
