Jadi has an experienced research team to develop conventional toners for use in photocopiers, monochrome and color laser printers. The conventional toner research team is made up of two main divisions – monochrome and color. Although both divisions may have different research goals, they are structured into a collaborative high performance team to share expertise and technology to create an expansive network of knowledge for a result driven approach to research. Through years of knowledge sharing and research efforts, Jadi’s researchers have successfully developed a wide array of high quality products to meet market needs and customers’ requirements.
Combination chemistry forms the foundation of all conventional toner research activities at Jadi. It involves searching for the right ingredient and chemical mix that would deliver the best quality and print performance. This entails studying, testing and understanding the relationships and reactions of raw materials such as resins, charge control agents (CCA), waxes, silica, iron oxides and pigments, among others. Through scientific deduction supported by comprehensive test results and data, good toner formulations are established.
While formulations are important, it is crucial to understand the processing and manufacturing viability of conventional toners to determine production efficiency. Towards this end, Jadi’s conventional toner research team is constantly working with the production unit to analyze various processing parameters such as dispersion, melt flow index (MFI) and particle size distribution (PSD), among others, to achieve the correct specifications. Upon determining the formulation and the process parameter, pilot cases are produced and are thoroughly tested on photocopiers and laser printers at Jadi’s Performance Lab. All pilot cases and commercial products undergo stringent environmental test in a variety of conditions to observe their performance at different temperatures and relative humidity (RH).
In addition to developing excellent toner formulations, it is also important to study and understand the reactions between toners and various components within a laser cartridge. Some of the major components include Organic Photoconductors (OPC), Magnetic Rollers (MR), Primary Charge Rollers (PCR), Doctor Blades (DB) and Wiper Blades (WB). As these components could affect the print quality of a toner, it is vital to ensure that the toner and components do not have any compatibility issues. To develop toners which deliver consistently high quality print performance, Jadi’s R&D team works in partnership with most of the major component suppliers in the industry to design toners with wide performance window and high durability. Co-developments with partners around the world enable Jadi to keep up with the latest technological advancements in printing and imaging supplies to continuously innovate for the future.
