Installing the counter weight for adjusting the take-up/ feeding tension-bar weight
There are various types of media of different size of string and different texture. Further, even with the
same media, their stretching characteristics may vary due to differences in their pre-treatment process.
For printing such a variety of media applying appropriate tension for the media, there is a need for
adjusting the weight of the tension bar.
Depending on the attaching position of the counter weight, you can adjust the tension bar weight. (If you
attach it on the A part in the next pages figure, it may be heavier, and on the B part, it may be lighter.)
You can attach the counter weight up to 15 each for right and left.
• Attach the counter weight after adjusting the media feeding correction amount in P.2-34 "Set the
media feeding".
Media front surface at
setting
The print surface tightens.
Surface waviness
occurs on the media and
the printing surface comes
down.
As the media is pulled too
much, ruck partially occurs
between the pinch rollers
etc.
2-22
Phenomenon
At printing
Stable printing can
performed.
has
The media flops at printing.
The tension bar bends and
ruck occurs on the media or
the media skews.
Print result
Surface waviness or ruck
be
on the media is hardly
found.
As the print surface comes
down, printing cannot be
performed with the proper
head height. Therefore, the
printing quality deteriorates.
Ruck occurs on the media
may hit the head, and it
may cause the media jam
or the damage of the head.
Countermeasure
The tension is suited for the
media. It is not required to
adjust the counter weight.
Add the counter weight on
the A part of the figure
below to increase the
tension bar weight.
In addition, perform feeding
correction and set media
feeding properly.
Reduce the number of
counter weights set on the
A part of the next pages
figure, or add the counter
weight on the B part.
In addition, perform feeding
correction and set media
feeding properly.
