As part of our efforts to create energy-saving digital MFPs, Konica Minolta employs Induction Heating (IH) Fixing technology, which reduces power consumption during the fixing process and results in shorter warm-up time. In addition, this feature automatically cuts off residual fixing heat when no print jobs are taking place, further contributing to energy savings.

During the conventional fixing process, electric energy is converted into heat with a halogen lamp, and the fixing roller is heated by a thermal conduction system. IH Fixing technology allows us to directly heat the fixing roller electromagnetically, and quickly increase the temperature.

For this reason, energy consumption in the standby mode can be reduced, greatly contributing to energy conservation.

In 2005, Konica Minolta released the bizhub 750/600, which were the first digital MFPs to introduce the IH Fixing technology. At the time, these models led the industry in energy savings. One year later, in 2006, we introduced the bizhub C550, which similarly was the best energy-saving colour MFP in its category.

When it comes to forest resource conservation, paper use reduction in offices is important; double-sided printing is an effective means of achieving such reduction. The bizhub C650/C550/C451 realise high-speed printing when outputting double-sided colour pages, thanks to a paper feed control system that feeds three sheets alternately. This system offers productivity equal to single-sided printing, and makes it easier to reduce paper use in offices.

Konica Minolta's original Toner Loop Mechanism, which collects, circulates and reuses any toner that has not been transferred to the paper, is utilised for almost all of our black & white MFPs and laser printers. This process realises resource conservation by reducing the normally 5 to 10% of wasted toner to zero.
