Use this setting if you are unable to resolve
banding issues (horizontal striped lines or uneven
colors) in the standard print area (for cut sheets,
the area excluding the 1 to 2 cm strip at the
bottom of the paper) even after head cleaning or
head alignment.
Pattern selected
Press the Z button to print an adjustment
pattern. Measure the distance between the "+"
symbols.
Use only the distance between the center
symbols or the average of the distances between
the left, center, and right symbols.
After the adjustment pattern is printed, the
length of the pattern will be displayed in the
control panel. Press the u/d buttons to enter the
measured value and press the Zbutton.
Value selected
Choose an adjustment between -0.70 and
+0.70%.
Selecting too small a value causes dark bands;
adjust the amount upward. Similarly, choosing
too large a value causes white bands; adjust the
amount downward.
It is important to choose the appropriate amount
of suction for the paper used in order to maintain
the correct distance between the paper and the
print head. Choosing too high a value for thin or
soft paper will increase the distance between the
paper and the print head, causing print quality to
decline or preventing the paper feeding correctly.
In such cases, you will need to lower the paper
suction. The suction power is weakened when the
parameter is lowered.
Select High or Extra High if the paper wrinkles
during printing.
If Extra High is set, the following setting is
enabled: Setup menu > Advanced Settings >
Roll Paper Tension.
Select whether to enable (On) or disable (Off)
paper skew reduction.
