How to add ink to the printer? Some friends may not know how to add ink yet, so let's take a look at the printer ink tutorial below.

　　Step 1: First, remove the sealing patch from the ink injection hole, and then use the fine end of the ball pushing tool to press the steel balls in the ink injection hole into the box.

　　Step 2: Remove the rubber cap from the ink cartridge, insert the tip of the ink cartridge into the short needle and press it tightly.

　　Step 3: First, fasten the nut onto the top of the ink cartridge, then insert the ink cartridge into the ink injection hole, and screw the screw into the nut hole.

　　Step 4: Slowly push the piston by rotating the screw until all ink is injected into the ink cartridge (note: two ink cartridges must be added at a time)

　　Step 5: Remove the ink cylinder, place a new steel ball in the ink injection hole, and use the thick end of the ball pushing tool to lightly press the steel ball until it is flush with the hole. Then apply a circular patch.

　　Step 6: Press the ink nozzle of the ink cartridge tightly against the rubber key, and use force to press the tail of the ink cartridge into the protective clip.

　　Step 7: Remove the short needle of the empty ink cylinder, insert the mouth of the ink cylinder into the rubber key hole, and press it tightly. Reverse rotation of the screw causes the piston to bounce up and suck in 2-3 millimeters of ink, then gently remove the ink cartridge.

　　Finally, remove the ink cartridge from the protective clip, wipe off any ink stains with a clean tissue, and then install it for later use. At this point, the entire ink filling process is over, and your printer can start a new job.
