PAPER FEED ADJUST PATTERN Use this setting if you are unable to resolve banding (horizontal
striped lines or uneven colors) even after cleaning or aligning the
print head.
O Pattern
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.
Enter the confirmed number for each entry screen for lines
A to D.
O Value
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.
VALUE
DRYING TIME 0.0sec You can set the ink drying time for each print head pass. The
