Does the T-shirt you are printing on absorb
o
ink easily?
As it is difficult to force the ink to remain on the surface
of the T-shirt, misalignment may appear as lines due
to the unevenness of the T-shirt surface when
Bi-Direction (High Speed) printing is set for the print
head. If this occurs, do Print Head Alignment.
"Execute Print Head Alignment" on page 128
U
If the problem is not resolved by doing Print Head
Alignment, try setting Uni-Direction (Low Speed) for
Print Direction in Garment Creator for SC-F3000
Series, the software for the printer. To do repeat
printing or to print a job from a USB memory stick that
has already been set to Bi-Direction (High Speed),
set Head Move Direction to Uni-Directional on the
preview screen.

If lines are still visible, set either Color Print Quality or
White Print Quality to Quality.
Have you made the pre-treatment liquid too
o
weak?
If the cotton pre-treatment liquid has been diluted
too much, the solidity of the White ink is weakened
and the edges of the image may be blurred. Try
reducing the density of the White ink in the software,
or make the pre-treatment liquid stronger.
If the polyester pre-treatment liquid has been diluted
too much, the ink color development deteriorates.
Adjust the dilution ratio of the pre-treatment liquid.
Adjust the density of the White ink.
o
When printing on dark colored T-shirts, vertical
unevenness may occur depending on the base color.
If this occurs, try reducing the density of the White ink
used for the under-base. You can adjust the White ink
density in the printer's Garment Creator for SC-F3000
Series software.

Did you remove lint from the surface of the
o
fabric before applying the pre-treatment
liquid?
If pre-treatment is applied when lint remains, it can
cause unevenness. Use sticky tape (a roller) to remove
lint, and then apply the pre-treatment liquid.
"Applying the pre-treatment liquid" on page 43
U
Was the pre-treatment liquid applied
o
correctly?
Applying too much or too little pre-treatment liquid,
or applying it unevenly can cause uneven print
results. Apply the correct amount of pre-treatment
liquid uniformly.
"Applying the pre-treatment liquid" on page 43
U
Increase the temperature when fixing the
o
pre-treatment liquid.
Depending on the type of polyester, uneven print
results may occur even if the pre-treatment liquid is
applied correctly. In this situation, try increasing the
temperature when fixing the pre-treatment liquid.
This may improve unevenness.

Vertical ruled lines are misaligned,
small print is blurry, or a grainy
appearance
The print head normally prints when moving both to
the left and the right. While this is happening, a
misalignment (gap) in the print head may cause lines to
misalign, small print to blur, or create a grainy
appearance. In these cases, do these measures in the
following order.
