QSU (Quick Start-Up) is our original energy saving technology, developed to achieve effective power conservation for our copiers. Energy is consumed when a printer is turned on at full power, even if it is not in use. QSU enables a quick recovery from energy-saving mode. Since launch, QSU has been a huge success:- In 2001 we launched the first QSU multifunctional monochrome copiers, receiving the Minister of Economy, Trade and Industry Prize, the highest energy-saving award in Japan.
- Following that, we introduced HYBRID QSU, an integration of traditional QSU and capacitors (electric storage devices). This stores electricity to be used in sequential power ups.
- By 2006 we developed Colour QSU technology, which adopts the Induction Heating system, reducing recovery time for multifunctional colour copiers.
- QSU enabled us to produce the first model of its type with a 10 second recovery time from standby.
- The line up of QSU-equipped products now ranges from low-speed monochrome copiers to high-speed copiers.
QSU TechnologyThe fusing roller that fixes the toner on the paper was thinned as much as possible to shorten the temperature rise time. The temperature of the roller is effectively controlled by using twin heaters. Low-temperature fixing toner is also adopted. HYBRID QSU TechnologyThis technology incorporates capacitors (electric storage devices) into QSU technology to store electricity during standby so that it can be used for restarting and printing. This technology is incorporated into high-speed copiers. Colour QSU TechnologyThis technology adopts Induction Heating (IH) using a magnetic field to heat the fusing belt directly and quickly. This enables colour copiers to both be user-friendly and highly efficient. |
