Head Cleaning
About Head Cleaning
Check the printed test pattern result and perform cleaning
depending on the status.
Select one from the four types below:
NORMAL: When any line is missing
SOFT : When only head wiping is needed (when lines
are bent)
HARD : When poor image quality cannot be improved
even by NORMAL or SOFT cleaning
ULTRA : When poor image quality cannot be improved
even by HARD cleaning, or when the color
does not improve.
Perform head cleaning depending on
the test printing result
There are four types of head cleaning. Use appropriate
one for the test result.

.
• After selecting the head, press the [FUNC2] key

result.
• Repeat the cleaning and the test printing until the
printing result becomes normal.
Setting Media Correc-
tion
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.
Setting of Media Correction
A pattern for media correction is printed and a media-
feeding rate is corrected.
1
Set the media on the machine. ( P.2-4)
2
In LOCAL mode, press the key,
and then press
(ADJUST)
.
• The adjustment menu appears.
3
Press the key twice to print a
correction pattern.
4
Check the correction pattern and enter a
correction value.
• A screen for entering the correction value will be
displayed.
• Enter a correction value in "+":
The boundary between the two bands is widened.
• Enter a correction value in "-":
The boundary between the two bands is
narrowed.
• When you change the correction value by "30",
the width of the boundary changes by about 0.1
mm.
When the image quality is not improved after the
head cleaning.
• Clean the wiper and ink cap. ( P.5-6)
• Wash the head nozzle. ( P.5-9)
• On completion of [MEDIA COMP.] during use of
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; loose roll media can result in an inferior
image quality.
• When printing with a take-up device, set the media
first and perform media correction.
• 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.
