A "Supply Problem" message on the LaserJet 4050 USBMac 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 HP C4127X will clear it.
These quick tips apply to all laser printers. While your exact model may look slightly different, the steps are identical.
