Issue/ Error

1) Fuzzy blurry prints

2) Horizontal banding -

thin 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. (See section 6.1

Nozzle check)

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 shows some nozzle

missing

Nozzles all there but some

showing minor deflection

Countermeasure

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

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

perform head clean or cleans and

recheck nozzle to see if the

deflection is gone

See section 5 user manual

Perform head alignment procedure

(see section 7.1) make sure to rule

out the above reasons before this

adjustment

Perform head cleans until the CMYK

nozzles are 100%

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
