First, do an ink flush because the ink may have drained from the tubes and that's why you don't have a printout. This option is available in the printer driver. If this does not help, I then remove the head from the printer and rinse it with liquid to clear the heads. I use a syringe with a tube of the appropriate diameter. If you don't have access to such a liquid, you can use warm distilled water. If there is still a problem, please write here or to the e-mail address: endriuf.2@gmail.com. I'll try to help you.
