Head Strikes
What is a head strike?
A head strike is when the print head contacts, or strikes, a garment or platen
Results of a head strike:
If a head strike occurs, the print head may be damaged. If the head strike is
on a pretreated garment it will likely clog and may permanently damage the
print head.
How to avoid it:
Properly positioning the platen and mounting the garment so the head can
clear them.
What to do if you get a head strike:
Immediately lower the platen, prime all ink lines for a full pump cycle, wet cap
in Super Nozzle Cleaner, and contact tech support to see if permanent
damage can be avoided.
See pages 11-12 of the FreeJet 330TX User Manual for details about positioning the platen and setting its height.
See pages 14-15 of the FreeJet 330TX User Manual for details about mounting garments onto the platen.
One of the most damaging problems that can occur to your printer is a
Head Strike, or a Head Rub. Avoiding this will not only extend your
printer head’s life, but will save you both time and expensive repairs.

Environment and Shelf Life
It is important to maintain a temperature range of 60° to 80° Fahrenheit and
a Relative Humidity range of 45% to 65% to avoid negatively impacting:
● Print quality
● Proper flow and shelf life of ink
● Service life of print head
How does the environment impact print quality?
If the humidity is too high, fabric can retain moisture causing ink to bleed.
How does the environment impact ink?
The shelf life of our inks and pretreat material is one year, but temperatures
exceeding 80° Fahrenheit can cause the consistency inks and pretreatment
to permanently change, whether in the equipment or still in their original
containers. If this happens the ink or pretreatment should be replaced.
How does the environment impact the service life of the print head?
If the humidity is too low, atomized ink can dry on the print head plate and
cause clogging.

Startup Routine
Printer Startup: Ensure that your printer is ready to deliver a high-quality
print at the beginning of a printing session, before loading a shirt onto the
platen and printing.
1. Swirl the white ink in the ink bottles
2. Prime the white ink, followed by all colors
3. Run two head cleans
4. Confirm the platen is properly positioned
5. Set the platen height
6. Print a nozzle check
If the nozzle check isn’t good, you won’t get a good print.
If each square of the nozzle check pattern is 90%+ complete, proceed with
printing. If not, run another head clean. If the nozzle check is still not good,
repeat steps 2 & 3.
Contact technical support if repeating these steps doesn’t result in a good
nozzle check.

Setting Up a Print in DirectRIP
1. Load the image to be printed
2. Select the appropriate Environment for your garment
3. Set the desired size of your print
4. Set the position of your print (typically top-center)
5. Select the port that your printer is on
6. Set a margin, if desired
7. Set the white underbase choke (unless printing on a white
shirt)
Remember that the total size of your print design plus any margins must be
within your platen’s dimensions or an error will occur (12.5” x 18” on the
standard adult platen).
See page 15 of the FreeJet 330TX User Manual for more details about setting up a print job in DirectRIP.

DTG Success Formula
The ideal DTG print can be broken down to a simple formula that
illustrates the major elements needed to achieve high-quality prints with
vibrancy, and excellent washability.

Garment Selection
Choosing the right garment is the first step to
achieving high quality prints.
Qualities to look for in your garments:
❏Tight weave
❏Ringspun or Combed & Ringspun
❏Pre-shrunk
❏For blends, at least 50% cotton content
Qualities to avoid in your garments:
❏Loose weave
❏Moisture wicking
❏Anti-stain treatments
❏High levels of Spandex or Rayon
❏Colors/Dyes that stain when pretreated
This information is intended as a reference only. We recommend testing various garment
brands and materials to discover what works best for you.

Pretreatment & Print Quality
Whether using a spray gun for manual pretreatment or a pretreatment
machine, properly pretreating garments is crucial for getting high
quality prints.
Many print quality issues are caused by one of the following
pretreatment issues:
See pages 5-8 of the FreeJet 330TX User Manual for details about the pretreating process.
See pages 40-41 of the FreeJet 330TX User Manual for details about troubleshooting pretreatment issues
Pretreatment Issue Print Quality Result
Not enough pretreatment Grey whites and dull colors,
fuzzy edges in design, poor
washability
Too much pretreatment Very stiff feel after drying,
ink peeling or sticking to
folded fabric after laundering
Uneven pretreatment
application
Splotchy, inconsistent print
with both good looking areas
and bad looking areas
Remember that the amount of pretreatment referenced in the User Manual
is a guideline and use the above info to direct your pretreatment amount
adjustments when troubleshooting print quality issues.

Artwork Design for DTG
All good quality prints begin with good quality artwork, and the best quality
shirts and perfect pretreat application cannot correct problems with the image
being printed.
Aesthetic qualities aside, there are four important considerations when
creating or sourcing any artwork for DTG printing.
●Transparent background: Unless you want your print to be
rectangular, be sure to make the background transparent. This will both
make the subject of your artwork pop visually and save all the ink that
would have been used to print the background.
● 300 DPI resolution: The higher the resolution of your artwork, the
better your print can look. We recommend using 300 DPI to avoid
jagged edges on any curves.
● Size artwork to desired print size: Expanding or zooming in on
artwork causes jagginess, so create your designs at the size you’ll be
printing.
● PNG: Our recommended file format is .png for storage efficiency and
transparency support.

Maintenance
Printer Shutdown: Maximize the service life of your print head and
pump by following these shutdown maintenance procedures anytime
the printer will be idle for more than a few hours.
See page 26 of the FreeJet 330TX User Manual for more details on Maintenance.
1. Clean the print head plate brackets and the
undercarriage
2. Clean the capping station seal and wiper blade
3. Thoroughly flush residual ink out of the capping station
4. Wet cap the printer
5. Empty the waste ink bottle, as needed, or loosen the
cap to release any vacuum and then tighten it back up
6. Reposition the 8 ink clips, then clamp them shut
7. Confirm that the cleaning solution line’s clip is clamped
8. Shut off power from the rear switch
Performing the recommended maintenance is the most important factor
in maximizing your printer’s life and consistently getting high-quality
prints.

Maintenance
See page 26 of the FreeJet 330TX User Manual for more details about Maintenance.
Other Periodic Maintenance: The following maintenance needs to be
done periodically. How often it is needed will depend on how much you’re
printing, but use the following time-based guidelines to avoid potentially
scrapping a print due to a maintenance-related symptom occurring.

Consumable Parts
See page 60 of the FreeJet 330TX User Manual for more details about consumable parts.
What are consumable parts?
Parts through which ink travels will need to be replaced from time to time as
part of normal printer maintenance, not due to any flaw but because of
normal wear and tear.
Are consumable parts covered by the warranty?
The replacement of consumable parts is required as part of normal routine
maintenance for optimal performance and reliable operation, and is not part
of the warranty. Think of this as the normal car maintenance of replacing tires
and brake pads.
Are there any exceptions to consumable parts not being covered by the
warranty?
Yes, if a consumable part is deemed by OmniPrint staff to have been
defective on a brand new printer it will be covered by the warranty. We also
provide a 1-year warranty on the print head against spontaneous clogging,
which other manufacturers typically do not cover. (This does not cover
damage or clogging due to head strikes or lack of maintenance.)

Consumable Parts
How often do consumable parts need to be replaced?
The life expectancy of consumable parts can vary significantly, depending on
the amount of printing done and the diligence and thoroughness of
performing routine maintenance.
Here are some rough guidelines for how to expect consumable parts to last.
Consumable Part Typical Service Life
Pump 6 - 12 months
Damper 6 - 9 months
Short Ink Tube (damper
to main ink line)
1 - 2 years
FreeJet Clip 2 - 3 years
See page 60 of the FreeJet 330TX User Manual for more details about consumable parts.
We recommend keeping spare consumable parts on hand to avoid
potential downtime or expedited shipping costs in the event of a damper
or pump requiring replacement.
