DOD, the large character ink-jet printer, was designed and produced by our company in 2013.

It is high speed and high efficiency. There are more information about its parameters as follows, such as memory capacity, standard interface, physical features and its printing functions. 

how does DOD works?

the Print head of EC-JET large character inkjet printer (EC-DOD) consists of a group of miniature high-precision solenoid valve, once theSolenoid valve opens, ink located in the nozzleSpray outA droplet by constant pressure
EC-JET large character inkjet printer is different from small character inkjet printer.the ink droplet ejected without deflection but control the discharge of ink

Droplets by the solenoid valve. Each point corresponds to a head of miniature solenoid valves, 7 dots print head have seven solenoid valves, and 16 dots print head had 16 solenoid valves. through Electronic control module, a set of coordinated action solenoid valve can print a raster column in the product.When the product move, it will form the necessary information and patterns, providing a non-contact method of printing. the process is controlled by the electronics module which also stores the messages to be printed. the message is programmed using the touch screen
