Brother GTX pro Instruction Manual page 254

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.)
Did you shake the pretreatment
after its dilution?
Is the [Low Temperature Mode]
set to [Disable]?
Has the pretreatment been fixated
insufficiently?
Whiteness of print result is insufficient
Probable Cause
Has the pretreatment been
applied insufficiently?
Has the pretreatment been fixated
insufficiently?
Is there any nozzle that does not
eject ink-jet droplets?
Is the white ink circulated
insufficiently?
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.
Shake the pretreatment sufficiently.
Change the setting to [Enable (Normal)].
Check on an actual temperature of the heat press
and its pressure during the fixation stage.
Always keeping the lower iron (where media is
placed) of the heat press at heated temperature with
a heating source may solve this problem.
Remedy
Apply a proper amount of pretreatment.
Check on an actual temperature of the heat press
and its pressure during the fixation stage.
Perform [Head Cleaning] from the menu.
If no improvement is attained, follow the referenced
instructions.
From the menu, select [Maintenance] > [White Ink
Circulation] to circulate the white ink properly.
