When printing, there is always a lack of color or disconnection. What is the reason?
This may be caused by bubbles at the ink outlet of the ink cartridge. If the position of the broken line changes constantly during printing, air enters the ink bag of the nozzle, so clean the nozzle several times. If the broken line position does not change, the nozzle is blocked or the ink outlet has bubbles, so it needs to be cleaned and stopped for a while to try again.
