Paper Feed Adjust

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 print head cleaning or Head
Alignment.
There are three types of paper feed adjustment. We
generally recommend using the block pattern to make
adjustments.
Maintenance
Block Pattern
Two types of patterns are printed, and you can make
adjustments while inspecting the patterns visually.
This is useful for adjusting printouts with an emphasis
on printing images.
Crosshairs
Two types of adjustment pattern (crosshairs) are
printed in the center of the paper, and the distance
between the adjustment patterns is measured. This is
useful for adjusting printouts with an emphasis on
printing dimensions and lengths (CAD and so on).
Value
Adjust within a range of -0.70 to + 0.70%. Use this
when you want to move a little from the current print
position.

This section explains how to select Paper Feed Adjust
items from the control panel.
