Review on 🖨️ High-Yield Valuetoner Remanufactured Ink Cartridges for HP 952XL: Perfect Replacement for OfficeJet Pro 8710, 8720, 7740, 8740, 7720, 8715, 8702 Printers (2-Black) by Pop Henneghan

If you encounter any problems, you have excellent telephone support. I had a problem that happened regardless of whose cartridges I installed. The solution was simple. The technician explained to me that my HP printer has a cleaning program that I have to activate from time to time. Of course I haven't activated it since I bought the printer two years ago. After running the program a few times, I had no trouble printing, whether it was single-sided or double-sided. After a few years with these cartridges I am very satisfied.
