After the release of G&G’s reman ink cartridges for HP 738 series, it has now introduced the latest patent-safe solution for use in the HP’s DesignJet T-Series printers, fulfilling the large-format printing needs for those working on CAD drawings, GIS graphics, building blueprints and advert designs.

About the Printer

In November 2023, HP launched the DesignJet T850/950 series large-format printers, ideal for AEC (architecture, engineering, and construction) and GIS (geographic information system) professionals to deliver accurate lines, legible texts and amazing artworks. 

HP uses a flexible rubber bulb-like structure in many of its DesignJet ink cartridges. It’s an advanced technology pioneered by HP to detect the ink volume. However, this technology has posed many challenges for the aftermarket to develop replacement ink cartridges.

Common Challenges for Aftermarket

1. Ink recognition failure. The rubber bulb is pressed to recognize the ink. Once the pressure is too low, the printer displays the error of "Ink System Failure";

2. Frequent air infiltrating errors in the ink supply system;

3. Hard to overcome HP’s chip technology and develop the serial numbers;

4. Big ink droplets on the prints, unable to print small fonts and straight lines;

G&G’s Innovative Solution

G&G’s patented large-format CAD solution for HP 738 series successfully tackled these challenges with innovative structure, smooth user experience and reliable results.

•  Rubber bulb and micro-pressure valve design

This design efficiently prevents ink backflow when the printer mechanism presses the rubber bulb, which can avoid the error of "Ink System Failure." Additionally, each cartridge undergoes 4 rigorous testing procedures conducted by different precise equipment to guarantee quality and stability.  

•  Bubble-collecting structure

The structure effectively prevents bubbles from entering the printhead's ink chamber through the ink outlet. This will avoid breaks or the triggering of the "Ink System Failure" error message on the printer.  

•  Geehy (APEX) high-quality chips

G&G's ink cartridges are equipped with smart chips developed internally by Geehy to ensure quick recognition and accurate supply monitoring. Each cartridge comes with a serial code for users to recognize. G&G also regularly updates the serial codes to prevent recognition issues due to duplicate serial codes, giving users peace of mind.

•  EverBrite ink, superior performance

The 4-level nano ink filtration technology effectively intercepts the macro molecules to ensure the ejection of smallest ink droplets. This brings clear fonts and straight lines on the great artworks.
