Setting Of Media Correction; If The Positions Of Dots Shift - MIMAKI TS300P-1800 Operation Manual

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.
• When printing with a take-up device, set the media
first and then perform media correction.

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.

When the condition for printing (media thickness/ink type/
etc.) has been changed, perform the following operation
to correct the ink drop position for bidirectional (Bi)
printing and obtain the proper printing result.
• When using leaf media, set a media of more than A3
size put horizontally. If a media with narrow width is
set, printing will only be conducted to midway.
