How to inject the hp videotape beside a syringe?

hello..

I bought a fill up on kit for HP black ink 21. The female told me to insert the needle up to soft sponge which is the first deposit.. however it spilled so my brother inserted until the next complex layer.( I think).

so what do you reason? (My printer is working properly now). what is the proper way to insert the hypodermic?

If you don't go contained by far enough, it will soak the top part of the sponge first and filter out the top. If you go too far, you can pierce an celebrated piece of mesh placed between the sponge and printhead area. Go benevolently (always when refilling) until you meet somewhat resistance. Then you've gone far enough. Needle will turn in around an inch.



As for just wise saying the heck with it and buying cheap cartridges.. get sure your supplier fills them to their max horizontal vs what HP puts in them. HP puts 5ml, but they can hold up to 24 ml. Some suppliers are closer to 5 than 24.
It's not worth it. I worked at a place where on earth the guys did that all daytime. I didn't pay much attention to them. Unless you're an eco freak (no offense intended), I chew over you're better off a short time ago finding some cheap cartriges and recycling the antediluvian ones. It's too much work for too little.
