Solution: Reuse the Old Chips on the New M507, M428, and M404 Compatible HP Toners
Presently, the compatible HP M507, M428, and M404 toner cartridges (CF258A, CF258X, CF289A or CF289X) do not come with chips. These compatible toners will not automatically work when installed in a printer unless you remove the chip from the previously-used toner and place it on the new compatible cartridge. Reusing chips from previous toners makes sure that the new compatible toners are recognized by the printer. The process is very simple: use a pair of tweezers to slide the old chip out of it’s slot and then position it in the same location on the new cartridge. That’s it!
