High-Resolution Printers

Applying high resolution inkjet codes to primary and secondary package material, eliminating the need for pre-printed boxes and labels, helping to reduce inventory, scrap and waste.


  • Stand-alone self-contained, highly-compact unit, high resolution inkjet printer.
  • Simple, intuitive software operate by a 5” touch-screen reduces the potential for operator errors in efficiency.
  • Minimum intervention needed due to micro-pump built in the ink system, simply operation and achieve automatic ink delivery functions.


The DJ340 is designed for satisfying basic coding and marking need, high resolution codes up to 70 mm (2.8 in) print height, 17.5 mm (2.8 in) head is alternative which are compatible with the inks apply on porous and non-porous substrates with consistently high-resolution text, logo and barcodes printing.

System Structure

Compact design consist of 4 parts, ink supply, control unit, pump ink system, print head.





Control Unit

A 5″ full color touchscreen provides simple and intuitive software access to the system’s internal messages and print functions.

Satisfied With Basic Coding Need - Print message is flexible in layout with alphanumeric characters, box and lot number, date-time code, regular bar codes and graphics. Quickly access into printing.
Alternatively, messages can create and edit on Dotjet’s easy-to-use DotW_340 PC Software and transferred via USB device assisting for mess print message creation.

Controlled Extensibility
A simple accessory a mini wifi router implements multiple printers operation from a PC, or can be controlled and monitored remotely from a smartphone.

Ink Supply
Standard 250ml ink cartridge design ensures ease and contamination-free at ink run-out changeover. A secondary ink tank built in the system enables ink to be changed without stopping production.
Optional, the bulk ink supply requires fewer changes for greater uptime and lowers overall cost per code for cost-efficient.

Pumping Ink Delivery
Consists in three mini pumps implement one button to act Ink priming / purging / draining instead of manual operation, along with the waste is sucked into a container, easily operation and completely no mess in the system working.

Print Head Technology
Adopting Seiko and Xaar piezoelectric technology offers a robust and most flexible print directions downwards, vertical and horizontal and can be used with oil, UV, and solvent based inks and fluids.

Additional Heating Facility

Optionally built-in the print head, the design can keep the print head working at a certain temperature is capable of printing UV ink with a range of viscosity provided by your supplier, which may have particular adhesion ability to a specific material. The UV ink with the feature of high viscosity at a lower temperature, the difference depends on the ink design.

Encryption on the ink cartridge use
A security chip on the cartridge top detecting by the printer must be recognized then start up, ensuring ink business trail behind per inkjet printer sold. The chip also records ink consume volume and goes off alarm at ink at low status.
Empty ink cartridge supplied by Dotjet is available for distributors fill with the ink from own supplier.
