If your 8031 shows a "Supply Problem" alert, it's usually a chip-recognition issue rather than an empty cartridge. Power the printer off for about 30 seconds, remove the cartridge the printer is flagging, reseat it firmly, and wipe its chip contacts with a dry, lint-free cloth. If the alert won't clear, replace the flagged cartridge with a fresh unit or contact our support team.
