About the G20i

Traceability and the visibility of goods throughout the supply chain have never been so important – and so too is the need to print this information on secondary and outer packaging. Coding equipment needs to be versatile and robust, enable quick message changeover, create high resolution print, and be easy to set up and use for an operator to ensure high quality, error-free codes on every package.

The Domino G20i is a compact, all in one, single-sided carton coder ideally suited to basic text, date codes and graphics on outer carton secondary packaging. It is designed for straightforward self-installation, set up and use without technical knowledge.

The Thermal Inkjet print head provides sharp, high resolution codes on a variety of substrates without ongoing maintenance or support requirements. Easy and clear message creation means operators can avoid potential errors and costly re-work, keeping your production line running.

Domino Developed Inks

Domino's specially designed inks have been optimised for great performance on outer carton applications, and are designed for a wide range of materials including carton, paper and many more. A cost-effective consumable, the low ink consumption and maintenance free operation deliver a low total cost of ownership, and print perfect codes – even after extended production line stops. Domino inks offer lasting quality, with adhesion and contrast ensuring excellent code clarity and durability throughout the supply chain.

You can connect to the printer in three different ways:

  1. Through a Windows based connection to a PC
  2. Using the Bluetooth wireless keyboard included in the box
  3. With the Android application available to download on any Android (v4.0 or above) device.

There is space in the G20i memory for 3 fonts. You can change these fonts via the PC application.

The on board controller supports English (default), Simplified Chinese, French, German, Spanish, Russian, Portuguese, Korean, Polish and Vietnamese.

The Android app additionally supports Thai, Indonesian (Bahasa), Japanese.

Asian and Chinese characters can be downloaded using the PC connection.

The printer is not designed to work with Check Weigh applications.

The G20i is fully compliant to all health and electrical safety regulations and Bluetooth admitted in all countries where it is sold.

The printer is designed as a stand alone printer and is not intended to be networked.

TIJ stands for Thermal Ink Jet – a process where ink droplets are heated and as the ink expands it is ejected from the nozzle. This is a very accurate, fast and controllable technology.

Simply open the latch on the printer that holds the cartridge in place and remove any empty cartridge; then take the plastic protection clip off the new cartridge and slide the cartridge, electrical connectors facing down, nozzles facing forward into the slot; Ensure the cartridge is firmly located and close the latch. See the installation video to watch a cartridge being inserted.

The prints per cartridge depend on many factors including the size, complexity and font of the message being printed. The printer will give you an indication of the number of prints that can be made, based on each individual code created.

The printer is able to print a wide range of barcode types. For a good barcode quality the line speed needs to be consistent.

For lines which vary in speed an encoder is required.

The G20i is not supplied with an encoder; but industry standard encoders can be supplied and fitted by your supplier. Details on how to install an encoder can be found in the product manual.

The G20i is not supplied with an alert beacon, however these can be sourced from your supplier. Details on how to install a beacon can be found in the product manual.

Thermal Inkjet technology can print up to 600 x 600 dpi. For outer case coding applications image output of up to 300 x 300dpi is recommended.

Changing the language of the printer is an easy task from a menu option on the printer.

No, the printer does not have to be switched off, although the printing function should be stopped and restarted after the new cartridge is installed.

The printer can print at a maximum speed of 180m/min (590 ft/min) at 100 dpi horizontal resolution to 30m/min (98 ft/min) at 600 dpi horizontal resolution.

The maximum power output is 48W.

The maximum amount of fields and characters that can be added to one message is:

  • 20 logos per message
  • 6 lines with up to 150 characters per line
  • 6 counters
  • 2 clocks
  • 5 shift codes

The limit is 100 messages that can be stored on board the G20i.

Yes, one keyboard can be used for several G20i printers, but the matching dongle needs to be connected to the printer.

As each keyboard is matched to the bluetooth dongle that is supplied with the keyboard, the keyboard will only work with this dongle. To use the keyboard on another G20i printer the dongle will need to be plugged into the G20i printer.

The G20i printer can support over 110 different barcode types.

For the full list of supported barcodes please go to the product manual for the G20i.
