Head Cleaning
About head cleaning
Check the printed test pattern result and perform cleaning
depending on the status.
Select one from the three 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
Perform head cleaning depending on
the test printing result
There are three types of head cleaning. Use one by
checking the test pattern.
1
Press the
(TEST PRINT/CLEANING)
key in LOCAL.
• CLEANING MENU will be displayed.
2
Press to select the cleaning
type.
• NORMAL : Select this if any line is missing.
• SOFT : When only head wiping is desirable.
(in case of bent lines)
• HARD : Select this if inferior printing cannot
be improved even by [NORMAL] or
[SOFT] cleaning.
3
Press the key.
4
Perform test printing again, and check the
result.
• Repeat the cleaning and the test printing until the
printing result becomes in normal.
Setting of Media Cor-
rection
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 a media. ( P.2-4)
2
Press the key, and then press the
(ADJUST)
in LOCAL.
• ADJUST MENU will be displayed.
3
Press the key twice to print the
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.4-6)
• Wash the head nozzle. ( P.4-7)
• 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.
• 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.
