Features and advantages of our technology
[Low-temperature fusing toner via pulverization]
Approximately 70% of a printer or copier’s total energy consumption occurs through the process of fusing paper and toner.
Energy saving is essential for environmental conservation and eliminating impacts on the global environment. Hardware manufacturers are actively developing and promoting methods for lowering fusing temperatures.
Toner that can be melted and fused at low temperatures is necessary from an operational and functional standpoint. In polymerized toner, a capsule-structure contains large amounts of wax which contributes to the fusing process, and core-shell structures using resins with different glass transition points have become mainstream, with each company placing a strong emphasis on low-temperature fusing.
However, to ensure toner produced through a pulverization system excels in offset resistance while maintaining low-temperature fusing properties, it is essential to incorporate attributes such as a high proportion of low molecular weight resins, and large amounts of wax. This requires technology that is extremely difficult to utilize in terms of the pulverization process.
With conventionally designed toner, the offset range is insufficient and fusing defects can easily arise due to factors such as the surrounding environment, paper or printing methods. Our company has introduced new toner designs as a means to counter these problems, with the aim of achieving a practical toner that has a wide fusing range and superior gloss properties, amongst other benefits.
Patent No. 7141732 “Electrostatic Charge Image Developing Toner and Toner Cartridge”
[Toner with high charge stability]
Since toner is transferred using static electricity, the amount of static electricity (referred to below as triboelectric charge) becomes an extremely important factor.
The triboelectric charge can be controlled by resin and external additives, but it is possible to maintain high and stable triboelectric charge mainly with substances called charge control agents (CCA).
In recent years there has been a trend toward CCA-free products due to environmental considerations. As part of our environmentally conscious approach, our company has successfully developed toner with high charge stability by adding substances with special charge-inducing properties to maintain the required triboelectric charge without adding any CCA.
About toner cartridges
About recycling toner cartridges
We receive used laser printer cartridges from customers, disassemble them one by one, clean them, and repair damaged areas. We have established a recycling system where we fill these with new toner, reassemble them, and deliver them to customers.
Resource recycling
Until now, humans have continually used Earth’s resources – such as oil and coal. It is said that these resources will be depleted within a few decades.
Furthermore, consumption of fossil energy such as oil and coal leads to carbon dioxide emissions, accelerating global warming.
We are participating in building a sustainable recycling-based society by recycling limited resources whenever possible.
Recycling system
We support a “receive and remanufacture” system, where we receive cartridges from customers and deliver recycled products. Furthermore – depending on the model – we also support a “pool system” where we deliver previously remanufactured cartridges.
Association of Japan Cartridge Remanufacturers
We are a regular member of the Association of Japan Cartridge Re-manufactures. Our company is an E&Q certified member, having cleared the Environment and Quality management standards established by the Association of Japan Cartridge Re-manufactures (AJCR).
