Let’s discuss your problem with the Uninet 100 DTF printer's white ink, which is not printing.
 
Why is the White Ink Not Printing?
Since your printer has no problem printing other colors, but white fails, the issue is most likely in the white ink system causing the failure, not a general electrical or mechanical fault with the printer. The printhead and mainboard are okay since other colors work. For example, one of the most common causes of white ink failure is clogging, a constant issue we see with DTF printers due to the unique makeup of white ink.
 
The Most Common Causes of a Clogged White Ink
 
Inside The Ink Block Area Or Nozzle
White ink is thicker than any color and tends to settle and dry inside the ink lines or nozzles if the printer is not used regularly. 
 
Solution: Run an appropriate printhead cleaning cycle according to the manufacturer's specifications. Don’t over-clean, though; over-cleaning can ruin the printhead.
 
Line Blocked or Ink Cartridge Issue
If you change the ink or ink lines, air bubbles or dried ink can clog the system. 
Solution: Check that the ink lines joining the white ink cartridge are not blocked. Minor blockages can be removed by running a manual cleaning cycle.
 
White Ink Lines with Air Bubbles
With white ink, air can enter the ink system and stop it from reaching the printhead. 
Solution: Most DTF printers have a priming function in the maintenance menu. You can use this feature or prime the ink lines manually to push any trapped air bubbles out.
 
Printhead Nozzle Clogging
White ink tends to dry faster than other colors, leading to blockages that stop ink flow from the nozzles. 
Solution: Clean the printhead using a specialized cleaning solution for DTF printers.
 
To troubleshoot clogs in white ink
Perform a Cleaning Cycle
First, run a white ink cleaning cycle to clear minor clogs or air bubbles. If the Cleaning Cycle has not resolved the issue, perform manual cleaning.
 
Prime the White Ink Line
Use a priming tool or manually check the ink flow to remove air bubbles and clogs.
 
Flush the White Ink Nozzles
If you believe the nozzles are clogged, use a unique cleaning solution to unclog them. Be careful—cleaning too much can cause damage. Always follow the manufacturer’s instructions.
 
Check the Ink Consistency
White ink may settle or thicken in the cartridge, preventing it from flowing well. 
Solution: Mix your ink before use. If the ink has dried too much, replace it.
