Hp817 color ink cartridge method, can solve the problem of no red

Problem: A hp3538 color inkjet printer that has been in use for a long time, the ink cartridge has not been added with ink, but the red color is no longer available. printing the red color will print the orange color directly, which is very annoying, I searched a lot of information and finally solved the problem.

 

Solution (I have summarized it myself)

1. air hole, look carefully above the ink cartridge, will find some thin lines, those are very useful, used for ventilation, the paper pasted on the ink cartridge, very clever, be careful when tearing it apart, and re-paste it after adding ink.

2. Color hole layout. Most 817 ink cartridges have 5 holes. The top is red, the left side is yellow, and the right side is blue. If you are not at ease, you can use the toothpick Test Method of the heroes.

3. activate the red vent hole by yourself. The red vent hole itself is sealed. It is estimated that the manufacturer does not want to make our own ink. All of us manually activate it, that is, the red hole is next to it and looks like a hole, but the one that is plastic again, use a knife or other tools to activate it.

4. When adding ink, it is best to use a syringe to conveniently observe the volume and speed of ink injection. Basically, stop without injecting 0.2ml and wait for it to spread. Once the color is increased to around ml, insurance practices.

5. The ink cartridge can be cracked and cleared. You can use the paste method of the heroes to crack it perfectly.

 

At that time, I thought that after a long time, the nozzle was blocked, or the ink cartridge was broken, the reason was: the red ink itself was used very quickly and basically it was almost gone, so when I injected ml of red ink with a syringe and used the paper to test the nozzle, the red ink appeared, proving that the ink injection was successful and that the problem could not be solved in red, in the future, when adding ink, you should pay attention to it. Do not wait for the ink to be added. When there is about 1/3, you will start to add it. If you add about ml, you will be OK. If a color does not appear, do not give up or worry. analyze the cause and believe that you can solve the problem.
