Paper Feed Adjust
Pattern 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.
When “Pattern” is selected;
Press the [OK] button to print an adjustment pattern. Measure the distances between
the “+” symbols in the printed adjustment pattern. 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 printing, the length of the pattern will be displayed in
the control panel. Press the [
S ]/[ T ] buttons to enter the measured value and press
the [OK] button.
When “Value” is 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.
Value
Paper Suction -4 to 0
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.
If this happens, lower the paper suction. The suction power is weakened when the
parameter is lowered.
Roll Paper Tension
Normal
Select “High” or “Extra High” if the paper wrinkles during printing. High
Extra High
