To replace a cartridge: power off the printer, remove the old cartridge, wipe the nozzle area with the supplied cloth, and install the new food-grade cartridge until it clicks.
Wear gloves to avoid skin contact with ink, and keep ink and cleaning fluid away from eyes and mouth. After install, run a test print on an egg tray to confirm the code lands cleanly on each eggshell and reads at a glance.
Many systems show remaining ink level on screen, so you can plan replacements before a run rather than mid-batch.
