The RIC 842126 cartridge has an approximate yield of 37000 pages.
The "Supply Problem" notice on the MP4054 is typically a recognition fault, not a defective cartridge. Start by turning the printer off for 30 seconds. Reseat the cartridge, clean its chip contacts with a dry cloth, then power back on. If nothing changes, the fix is a fresh RIC 842126.
