Nozzle clogging on an egg printer is prevented mainly by regular use and automatic cleaning. TIJ systems with sealed, plug-and-play cartridges avoid the open ink tubes that clog in older CIJ setups. On a packing line a stalled head matters, because uncoded eggshells back up on the conveyor within seconds.
Tips: run the auto-clean cycle on shutdown, keep the machine powered in standby (many clean automatically), use only recommended food-grade ink, and store cartridges properly.
If a clog appears, use the built-in purge/clean routine and approved cleaning fluid rather than forcing the head.
