Brother GTX600SB Instruction Manual page 270

The edges of the image are blurred, characters and straight lines are doubly printed and printed
result appears too granular
Probable Cause
Is the platen positioned at a level
that is too low?
Is the ejection timing correct?
Is the image enlarged on the
printer setting screen?
Thin color cannot be printed out well gradually
Probable Cause
Is the ambient atmosphere at a
high temperature and very dry,
which in turn tends to cause the
nozzle surface to dry up?
White ink is not printed out evenly
Probable Cause
Has the pretreatment been
applied unevenly?
Has the pretreatment caused
any change in hardness or
deformation of the pretreatment
roller? (This applies to the case
where the pretreatment roller is
used.)
Is any water content attached to
the pretreatment roller after the
pretreatment is fixated?
Is there any lint, yarn waste,
dust, etc. that are attached to
the surface of pretreatment
roller? (This applies to the case
where the pretreatment roller is
used.)
Remedy
Adjust the height of the platen corresponding to
the print medium before using it.
You can use the platen height adjustment lever
from the menu to adjust the height of platen.
As a rough indication, adjust the height so that it
is lowered by one step from the limit height
detected by the obstacle sensor, and check that
the platen is not detected by the sensor.
Adjust the ejection timing again. It is likely that
the setup value is incorrectly set after replacing a
print head or the platen with a new one, or after
adjusting the platen height.
When a low resolution image is enlarged on the
printer setting screen, it may blur or angle the
image. Pattern data should be enlarged on an
image editing application, and its roughness
should be checked.
Remedy
Perform the flushing more frequently. In addition,
increase the flushing volume.
Remedy
Apply the recommended amount of
pretreatment evenly to the target area.
After the pretreatment roller is used, put it in a
plastic bag or the like hermetically to prevent it
from drying up, and keep it in a flat place in an
upright position.
Also, when it remains unused for two weeks or
longer, wash it well with running water, and let it
dry in a shaded area.
Prevent water content from being attached to
the roller after the pretreatment is fixated.
Clean the surface of the pretreatment roller.
