When the DTG printer head is blocked, power on the machine, then go through the self-check function of the machine and use the automatic cleaning of the printer properties. If it can, there is no need for the next step.
When the above-mentioned method does not work in one step, you need to use maintenance software to clean it forcefully.
If the head cannot be completely cleaned in the second step, you need to power off the DTG printer, then unplug the power, plug, computer data cable, etc., drop the cleaning fluid on the dust-free paper, and pull out the head to the middle position to protect it. The appearance of the head (can not wipe the nozzle while protecting the nozzle), about 5~6 minutes, then push the head back to the original point and then test according to method 1 step or 2 steps.
If the method fails in 3 steps, you can try to power off the DTG printer, then unplug the power supply, plug, computer data cable, etc., move the print head to the original point, suck up the waste liquid bottle with a large syringe, and see if there is any waste ink Drop it, and then test according to the method in step 1 or step 2.
Check which color or which color of the print head does not produce ink, for example, yellow ink is not good, power off the DTG printer, then unplug the power supply, plug, computer data cable, etc., just at the air inlet of the yellow ink bottle. Use the syringe to blow air quietly (to prevent the air from the syringe from flowing back, causing the ink to flow back, or to blow the ink bag too hard), while checking the surface of the head to see if there is ink oozing out, about 2~3 drops of ink oozing out, and then Use dust-free paper with a drop of cleaning fluid to quietly dip the ink on the surface of the print head, move the print head back to the original point, and then test according to step 1 or 2 of the method.
If the above 5-step method fails, you can only use the bubble head method. After the soaking, follow the method to test in 1 or 2 steps. If it still does not work, you can only change the head.
