11 Troubleshooting Guide
Issue/ Error Possible reason Countermeasure
1) Fuzzy blurry prints Table height is to low For most T-shirts the indicator below the
height adjustment knob on the table
should be set to 0 or near 0. The best
printing is achieved when the print head
is 1.5mm away from the printing surface
Too much ink (oversaturated)
causing bleeding (mostly for
white or light shirts without
pretreat Check the settings in the RIP - especially
rendering intent (perceptual is default
and should be used in most cases). Make
sure the ink set and profiles are correct.
Profiles meant for 600 x 600 dpi will have
to much ink if 1200 X 1200 dpi output is
selected
Nozzle check shows all nozzles
but some areas show deflection.
(See section 6.1 Nozzle check) perform head clean or cleans and
recheck nozzle to see if the deflection is
gone
For dark shirt with a white under
base- poor pretreat - Not enough
pretreat can make the white can
CMYK areas of print to appear
dull or fuzzy. Especially if a
section of the print appears sharp
and another section appears dull
or fuzzy See section 5 user manual
Head alignment is off Perform head alignment procedure (see
section 7.1) make sure to rule out the
above reasons before this adjustment
2) Horizontal banding -
thin horizontal lines
across the entire shirt Nozzles missing - if nozzle check
shows some nozzle missing Perform head cleans until the CMYK
nozzles are 100%
Nozzles all there but some
showing minor deflection Check table height - the effect of any
deflection will be exaggerated if the
printing surface is too far away from the
head - For most T-shirts the indicator
below the height adjustment knob on
the table should be set to 0 or near 0.
The best printing is achieved when the
print head is 1.5mm away from the
printing surface
Perform head cleans until the deflection
is reduced
Nozzles 100% and little to no
deflection Perform table alignment procedure (see
section 7.2)
