4-4 Optimizing Printing to Match Media Thickness
Description
The movement distance of media experiences subtle changes due to the thickness of the media and the temperature of the
media heating system. When the movement distance becomes discrepant, horizontal stripes are more likely to occur during
printing. We recommend performing correction to match the media you're using and the media heating system. Repeat the
process of printing a test pattern and entering a correction value several times to find the optimal value.
Note, however, that you can also make this setting on the computer (by, for example, choosing the media type in the soft-
ware RIP you are using). Use this feature when you want to make the setting on the printer, without changing any settings
on the computer. When you have made the setting on the computer, the computer's setting is used and the printer's setting
is ignored.

Description
If white or dark-colored stripes appear during printing, you can change the feed-correction value without stopping the
printing operation in progress. If white horizontal stripes appear, you make the correction value smaller. If dark horizontal
stripes appear, you make the value larger. You can change the correction value regardless of whether settings made on the
machine or settings made on the computer take precedence. A correction value set while printing is in progress is saved
only as a setting on the machine.
When the data contains crop marks, the feed-correction value cannot be changed while printing is in progress.
