A "Supply Problem" message on the NP6550 usually points to a chip-communication hiccup rather than an empty cartridge. Power-cycle the printer (off for 30 seconds, then on), reseat the cartridge until it clicks into place, and gently clean the gold chip contacts with a dry cloth. If the message returns, a replacement CNM F421001100 will clear it.
