7 Troubleshooting Guide
Issue/ Error
1) Fuzzy blurry prints
2) Horizontal banding
thin horizontal
across the entire shirt
3) Horizontal banding
thick horizontal lines
across the entire shirt
Possible reason
Table height is to low
Too much ink (oversaturated)
causing bleeding (mostly for
white or light shirts without
pretreat
Nozzle check shows all nozzles
but some areas show deflection.
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
Head alignment is off
- Nozzles missing - if nozzle check
lines shows some nozzle missing
Nozzles all there but some
showing minor deflection
Nozzles 100% and little to no
deflection
- Nozzles 100% - appears in solid
colors of dark or gray - bi
directional banding - has to do
with the colors laying down in
different sequence depending on
which direction the carriage is
traveling
Countermeasure
Perform adjust height with the shirt or
other garment you are printing on the
platen – if you were printing on a thick
fabric and move to a thinner fabric then
the thinner fabric will be to far away
from the print head if you do not
perform adjust height.
Check the settings in the RIP -
perform head clean or cleans and
recheck nozzle to see if the deflection is
gone
See under base settings
Perform head alignment procedure
Perform head cleans until the CMYK
nozzles are 100%
Check table height – Perform adjust
Hieght
Perform head cleans until the deflection
is reduced
Perform table alignment procedure
Select unidirectional printing in the RIP
