Yes — the replacement fuser for the T640tn is: LEX 40X2592, LEX 40X2665, LEX 40X0121.
The T640tn uses these maintenance parts: LEX 40X0100, LEX 40X0101.
A "Supply Problem" message on the T640tn 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 64015HA will clear it.
