UniPrint Printhead Cleaning Kit Refill Tool for HP 11 10 82 84 85 for hp Designjet 500 800 510 130 815 100/110/111/813/850 Printer Head Nozzle 800

Only issue I had was holding the printhead in the clip to maintain a seal while pulling on the syringe. So I ended up using a zip tie to hole the printhead in place and using one hand to hold the syringe body and one hand to pull up on the plunger. Primed all 4 heads in about 10 minutes. Do the work over something you don't care about. I layered up some old towels and had a bunch of rags ready, it is a little messy but not too bad. You will get ink on your hands, recommend using latex gloves.

This works great for priming empty printheads. Has helped me save several heads. It’s messy though: use a tray to catch spilled ink, and wear gloves!

Pictured with the kit was a needle for filling but was not part of the received kit.Edit: the needle was in the syringe, between the plunger and the body. The unit worked great and my print head is now working again.

worked very well and solved my issues

this is a refill only tool NOT for cleaning

The product worked as described. Very happy with a fast delivery too.Thank you Amazon.
