Review on 🖨️ HOTCOLOR 564XL Photo Black Ink Cartridge Replacement for HP564XL CB322WN Ink Cartridges - Compatible with HP Photosmart 7520 c309g 7510 7525 b210e Printer (3PBK, 3 Pack) by Mark Harris

I've spent a few hours on YouTube trying to clean/repair the printhead on my HP Photosmart 7510 but no luck it just didn't print anything black . A new cartridge and all those efforts failed, so I took a chance and bought this replacement head. I was a little concerned, but it all turned out to be for nothing. The seller shipped my order immediately and it arrived earlier than promised. I removed the old printhead, put in new and new ink and we're back in business. I have compared the print quality to previous prints and the quality is almost identical. Haven't tried photo printing yet, but I assume it's just as good. I recommend this product and this seller if you want to avoid all the extra work trying to revive a failed printhead for your HP Photosmart 7510.
