Yes — the replacement fuser for the T520dn is: LEX 99A2423.
The T520dn uses these maintenance parts: LEX 99A2420.
A "Supply Problem" message on the T520dn 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 LEX 12A6735 will clear it.
