If the printer cannot detect the new cartridges as a whole, all of them, then it will stay in One Cartridge Mode or Single Cartridge mode. If swapping and checking and re-seating the cartridges has no result to get it out of One Cartridge mode, not even with shutting off the printer for several minutes or longer and turning it On again, the printer might be defective, perhaps. (And if so, if within 1 year of purchase date, contacting HP about it and putting in a defective-within-warranty claim, for free service-repairing under warranty terms, would be the right thing to do.)
