Review on 🖨️ SOKO Remanufactured Ink Cartridge Replacement for HP 61XL 61 XL - Envy 4500 4501 4502 5530 5535 Deskjet 1000 1055 1056 2541 2549 3000 3050 Officejet 2620 Printer Tray - 1 Black 1 Tri-Color by Aaron Gonzales

Was initially happy with both color and black cartridges but after a short time my HP 4635 rejected the black cartridge and insisted it had to be removed. When a replacement black cartridge was installed, the printer displayed a message on the control panel stating that the color cartridge also "needs to be removed". The printer does not work with any of them. Now works great with two other replacement cartridges purchased from Revain.
