Yes — the WorkCentre Pro 555 uses a replaceable imaging drum: XER 113R457.
A "Supply Problem" message on the WorkCentre Pro 555 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 NEC S3522 will clear it.
