4-5 Making Corrections for Printing
Feed Correction
This corrects for errors in the amount of feed of the grit rollers due the type of media. Be sure to make this setting when
you have replaced the media with a different type. Correcting the amount of feed improves the dot-positioning accuracy
in the feed direction, which can help enhance image quality.

Perform correction to ensure uniform dot spac-
ing: If there are gaps in the test pattern, reduce
the value. If there are overlapping areas in the
test pattern, increase the value.
When correcting the amount of feed, set the same conditions for the type of media used and the configuration of the media (roll
media or sheet media) as when actually performing printing.
When performing printing test for feed correction, load the media correctly (see "2-3 Loading Media"). If the media is not
loaded correctly, an accurate correction value may not be output.
When you can set the error for the amount of feed for the grit rollers on the computer, the computer's setting takes priority. To
make the machine's setting take priority, turn off the computer's setting.
