Chapter 2 Basic Operation

Setting of Media Correction

Correct the media feed amount to match the type of
media you are using.
If the correction value is not appropriate, stripes may
appear on the printed image, thus resulting in a poor
printing.
• On completion of [MEDIA COMP.] during use of a
roll media, the media returns to the printing origin.
Then the roll media in the rear of this machine will
slacken.
Before printing, take up the slack in the roll media
by hand; a loose roll media can result in an inferior
image quality.

Setting of Media Correction

A pattern for media correction is printed and a media-
feeding rate is corrected.
• Two bands are printed in the correction pattern.
• Make adjustment so that an even color density is
obtained in the boundary between the two bands.
