Review on 🖨️ VAKER Remanufactured Inkjet Printer Ink Cartridge Tray Replacement for HP 63 63XL Combo Pack - OfficeJet 3830, 5255, 5258, 5200, 4650, 4655, Envy 4520, 4510, DeskJet 3631, 3639 Printer (Black & Tri-Color) by Adam Rogers

The cartridges are the correct size and shape of the HP 63 and each is easy to install, but the printer recognizes each one as a 'fake' (my word, not a machine). Although the printer does not display a message that it is not suitable for the HP product, none of them (after many attempts) printed a single page. It was no different than printing out a copy of a blank sheet of paper. Again, this is not an "operator error”; Rather, I suspect that the chip on the cartridge is not synchronized with the machine. Also, it should be noted that I have successfully used other universal refills in this machine. For me, however, this is a return to the expensive HP 63 or any other brand I've bought before.
