Epson L1800 DTF Printer Color Partially Not Printing Solution

Question: My Epson L1800 DTF Printer has stopped color printing. I ran several print head cleanings, and the nozzle check indicates everything is printing out fine. I had one design print perfectly; it would only do white ink the next time. Why this issue happens

Answer: Thank you for contacting us.  We at BCH Technologies want to ensure you get a detailed, thoughtful response. We greatly appreciate your engagement, especially with our YouTube channel, BCH Technologies [https://youtube.com/@bchtechnologies]. Your feedback helps us refine our expertise and bring you better solutions.
So, let's put some light on the problem of your Epson L1800 DTF printer:
That a nozzle check was printing correctly for all colors while the design you printed output nothing but white could point towards issues in your software setup or ink flow instead of a mechanical hardware error. You stated that the first design printed fine, so it's likely not a permanent wrong nozzle or printhead issue. This will then prompt us to look at other potential reasons for this:
 
Setup the RIP Software: many errors are born in how your RIP is set up. Some RIP software, like Acro RIP, has a function of printing white and color separately. If the software settings are unsuitable for DTF printing or an error occurs, then your printer will print only a white layer. Make sure color printing: Profile Layer is correctly set in your software settings, and the true white profiles are applied for both. If you can, re-install the RIP software to remove any chance of a blundering piece of another application associated with the ripping portion.
 
Ink Pressure: As you mapped all colors with a clean nozzle check, this means that the problem is in ink pressure. Barometric tank system for ink supply on DTF printers Poor Tank Placement: This issue would not allow your tank to deliver the ink fast enough into the print head, and it would spray out with a delay. Prime Your Tank Properly. Also, see this guide on how to prime CIS tanks.
And also, where you put the tank is super important. If the tank is below the printhead level too far, it can create insufficient or no pressure to get ink through. The tank should be at the height the manufacturer requires, which is, in most cases, described in this article). When the tank is a bit low, elevate your grip to maintain good ink flow.
 
Clogged Nozzles: Even if your nozzle check looks perfect, the buildup can accumulate with time, mainly due to the thick ensemble of pigments required in white ink used by DTF printers. Run another deep cleaning cycle and flush the printhead manually if necessary.
If the print head alignment is off (this can happen from cleaning or moving your printer), Align your printer payment settings in the maintenance tab and adjust if needed. This ensures that the white and color inks are printed as one.
