How to exhaust air to the ink cartridge in the printer? Take a few easy steps so you can do it yourself
Take the cartridge out of the printer and connect the entire set of ink bottles. Place it on a horizontal surface with the ink cartridge under and the sponge on top and ensure that there is enough ink.
Open the blowhole filter of the ink bottle and insert the syringe into the blowhole.
Take another syringe and place the nozzle on the sponge of the cartridge.
Push the first syringe to pump air into the stoma, and use the second syringe to drain the ink blister without wetting the cartridge chip below.
