Problem:
There is horizontal banding across print (in one or all colors).
Causes and Solutions:
You are using a 360 dpi Print Mode.
Use a 720dpi Print Mode. A 360 dpi Print Mode is the fastest but lowest quality where head clogs or
misalignment will show as banding.
The capping station is dirty and either not cleaning the print head completely or adding
more debris to the print head and causing print head to become clogged.
Thoroughly clean the capping station. It can be cleaned with swabs and cleaner. Be sure to clean the
plastic around the foam pad as this is where the print head will rest when the printer is not in use.
Also be sure to clean the rubber wiper blades as these wipe excess ink and debris off the print head
and will accumulate said ink and debris.
Ink in the nozzle opening has dried out from exposure to air for an extended period.
Do head cleaning and printing nozzle checks until a decent nozzle check is achieved.
Perform a powerful cleaning circle and check if a decent nozzle check is achieved.
A serious or permanent clog of the head may require replacing the print head. You can try doing a
power flushing using the syringe and Cleaning/Flushing Fluid. You MUST remove the head to do this.
Contact Tech Support for help.
Prevention:
Perform the daily maintenance task according to the intervals given in the description
Run head cleanings before printing in the morning as well as printing a nozzle checks to gauge status
of print head prior to printing onto garments.
Problem:
The quality of the printed output is unacceptable when printing images.
The images seem soft and are not clean and sharp. The resolution at the final size
is in 72dpi.
Causes and Solutions:
The resolution of the image is too low.
Resolution at 72dpi is for viewing the image on a computer monitor only. Images which are intended
for printing need to be a high resolution. If the image is not at a resolution between 120dpi and 300
dpi this causes the image not to have a good number of pixels therefore losing detail when the image
is printed out. You can try up sampling the image to a larger resolution but the image still will be
“soft” when printed.
Problem:
The print head is leaking ink and dripping ink all over the garments.
Causes and Solutions:
The print head was damaged by crashing into shirt plate, print bed etc.
Order replacement print head.
The capping station is dirty and either not cleaning the print head completely or adding
more debris to the print head and causing fibers and debris to collect ink and ooze or drip
ink.
Thoroughly clean the capping station.
Debris or shirt fibers collected on print head as well as print head carriage.
Using the reflection from the print bed gently clean the bottom of the print head and remove any
debris, dried ink and fibers.
Too much ink in the cartridges
If your cartridges are filled too much with ink, there could be too much pressure in the cartridge ink
lines and the ink is forced out of the print head. The cartridges should be filled below the air hole.
Altitude can have an effect.
High altitudes can also have an effect on the “pressure” in the system. If you are having an unusual
amount of problems and are in high altitudes, don’t fill the system too full and try adjusting the height
of the system.
The printer is not level
Not leveled printer has as result not leveled cartridges. This can also have an effect on the “pressure”
in the system. Check your printer if it is well leveled.
The dampers are faulty or exceeded their period of time.
Order replacement dampers
Faulty cartridges
Change cartridges
