DANA LN-6S Egg Coding Machine
Equipped with a conveyor, it reduces manual operation to reposition and automatically completes the coding of entire trays of eggs. The machine features six printheads arranged in a line. So it is capable of printing marks to six rows of eggs at once and meeting most egg packaging specifications on the market.



USB interface allows users to quickly import coding files, graphic logos, and font files, meeting diverse customer requirements for marking variety.
The six-printhead combination design allows for both simultaneous and independent use, offering flexible and practical options. It can code up to 30 eggs on a single pass, ensuring high production efficiency.


2. A photoelectric sensor is installed at the conveyor end, which automatically stops the egg tray when it reaches the end of the conveyor line, preventing damage to the tray or the eggs.
3. Universal wheels are mounted under the support feet, making it easy to move the machine, saving time and effort.
4. The built-in cartridge detection function dynamically displays the remaining ink level; multiple indicator lights allow users to clearly monitor the status of each cartridge.
5. USB interface allows users to quickly import coding files, graphic logos, and font files, meeting diverse customer requirements for marking variety.
6. Eliminating the complex ink system tubing of traditional coding machines, avoiding the common issue of clogged nozzles from infrequent use. The cartridge requires no cleaning, is plug-and-play, and is simple to maintain, offering economic and environmental benefits.
7. Featured printhead buffer devices, and the printheads automatically rising up when eggs pass, preventing collisions while ensuring coding quality. Motor-driven automatic height adjustment for the printhead makes coding of different sizes of eggs worry-free.
We can see more and more eggs are printed with marks like the date, brand name, logo, feature, etc, in grocery store, in supermarket, or in a bazaar. With those informative marks, comsumers are likely to be convinced that these eggs are more safe and worth higher price.
In the other way, printing code and mark on the egg help the farmer or trader track the sales and services.
To build up the brand and enhance the egg competitiveness on the shelf, DANA LN-6S EGG CODING MACHINE is your good helper.
