I have not installed the Black 202X cartridge as yet and have gotten at least 25 clear copies even though my LaserJet MFP M281fdw tells me that my printer needs attention.
OEM cartridges are the way to go with HP laser jet printers. I have tried other brands that are "compatible" with HP OEM cartridges but always had issues. Save your money and use HP cartridges as they are the most efficient and dependable cartridges around. Quality speaks for itself.
