HP Photosmart 5510/5520 Won't Print Black • Purge Unit Repair & Printer Refurbish

Hi
In this video, I'll perform a repair on an HP Photosmart 5520 sent to me by one of my subscribers!
This printer was not printing black, and he already replaced the printhead so it was something different. These printers have a widespread issue with the purge pump, part of the purge unit (cleaning unit/service station), in a few words black ink clogs inside of the pump and it gets stuck. As the purge pump doesn't work anymore, the printhead cannot be cleaned nor prepared for printing. Replacement parts cannot be found anywhere, so the only (messy) way is to unclog it manually.
I would like to thank once again my subscriber who sent me this printer, without his support I couldn't be able to make this video, and it's one of my most requested videos since I made the video of the printhead replacement on the HP Photosmart 5520.
I hope this will be helpful, and hopefully less printers will end up in landfills.

100% not requested and totally up to you, but if I've made you save some money fixing your own printer, or you'd like to support my channel in general you could consider donating any amount you want here: www.paypal.me/paolomarcelli Thank you so much in any case.
