The check valve for the printer doesn't have any air in it, but it doesn't come out. It still doesn't work
From your personal statement, analysis of leakage, box of ink cartridges, ink the check valve back looked at the appearance of normal needle, injecting ink into ink box to see, I wish you good luckIn addition, I have not used check valve, the friend that has seen, personal speculation that there is a switch, should be misleading you
Just change the CISS, change after dozens of photos. There is air in the pipe, the printing document is half a page, and then a check valve is installed. After it is finished, there is no air in the pipe, but it can not be played. The nozzle is not out of water any more. The ink in the ink box is full.When the check valve is installed, you can print the test paper color is correct, but the document is a piece of white paper. No more printing later. Say at least one cartridge problem. Where does the check valve open? No, there's a switchChasing the answerNot quite clear, you change the model, the general print cartridge does not leak, the ink box for the gas hole to open, hose without bubbles, you can print normally.
1. Do you have ink in the ink cartridge? If not, you can't hit it;2, the ink box installation is in place, let the printer self check to see whether the instructions are normal;3, everything is normal, "maintenance" in the print head, not, deep cleaning;Generally normal, no, that might be a cup, change cartridgesIn addition, the check valve must be opened when printing, the cartridge is not placed high, and so on after processing
