Seeing "Supply Problem" on your 8840C? Before buying anything, power-cycle the printer, open the cartridge door, and reseat the cartridge the printer highlights until it clicks. Wipe the chip contacts free of dust with a dry, lint-free wipe. If it persists, swap the flagged cartridge for a fresh one or reach out to us.
