Prevention:
Usually when a color prints out wrong it is because a nozzle is clogged. If you are trying to print out
an orange image but all that prints out is yellow, then that means the magenta is clogged and that
pigment can’t mix to produce the orange. The biggest part of your TexJet is to check for is the capping
station. Make sure this ALWAYS stays clean. The print head uses this to dock when the printer is not
in use to ensure the print heads do not dry out. The print head also uses this during a head cleaning.
If the capping station is dirty, the printer can not do a head cleaning properly, thus not working out
the nozzle clog.
Problem:
The printed image is wiping off, washing out, fading badly or bleeding.
Causes and Solutions:
Garment was improperly fixed.
Inks need to be brought up to approx. 150-180 degrees C. for 180 - 240 seconds for white and for
darker garments.
Too much or too little pressure applied when heat pressing.
When pressing the garment in the heat press the top of the heat press should gently rest over the
silicone paper. This allows the moisture of the inks to escape and properly fix.
Temperature of heat press is not correct (Either to hot or too cold).
Make sure the heat press is heating up evenly or correctly. (Should be 150-180 degrees C) You can
test this with a touch less infrared thermometer or heat testing strips.
Pretreatment improperly applied.
Pretreatment may still be wet. Simply fix longer. Poorly pre-treated? Apply more pretreatment on
successive shirts and fix again. To much pretreatment. Use less pretreatment in future. See
pretreatment on dark and colored textiles.
Type of fabric being printed
For best results print onto 100% cotton! With 100% colors will look their best. For 50/50 blends of
cotton and polyester ink needs needed to be fixed quickly to reduce possible bleeding.
How the garment is being washed.
Wash at maximum 60ºC and dry with delicate dryer settings.
Prevention:
Make sure heat press is heating up evenly and correctly. Heat press should lightly press garment. Pre-
treat evenly and away from printer.
Fix Pre-treat properly.
Problem:
The prints are out of register or there are large gaps or laps in the print.
Causes and Solutions:
The bi-directional print mode is enabled.
Change inside your printenvironment in the device settings the option named bi-directional. If you
want to print with bi-directional which is faster you have to consider that even if you do the head
alignment you may have prints out of register, because the distance between Printhead and garment
is not always the same.
Encoder strip is dirty and needs to be cleaned.
Clean encoder strip.
The Media comp offset value is wrong.
Change inside your printenvironment in the device settings the value for Media comp offset. At - if
there are gaps and +if there are lapped overprints
There is a communication error between your TexJet and your computer.
Make sure you don't have any jobs in the Polyprint RIP or Epson Queue's, if you do, delete them. Then
power down your TexJet & unplug the power & let it set unplugged for about 30 seconds. Power back
on and try again. You can also make sure you are set to use the correct port within printqueue.
Another possibility is the type of cable you are using. We highly recommend using a USB cable and
the best connection. And, do not use a long cable or switch boxes or hubs.
1. Make sure the port in is set to TexJet... in the queue menu port in the printqueue.
2. Open the Printers & Faxes menu from the Start button in Windows and open your printer, delete
any pending jobs.
3. Power down the TexJet and unplug it for 10 seconds.
Prevention:
Always double check the settings for Polyprint RIP prior to sending a print job to actually print. Clean
the Encoder Strip as needed depending on your production rate. Keep TexJet as clean as possible and
perform normal maintenance. Check the communication between the computer and printer.
