3 Two Part:
It is divided into two sections.First one is tonert supply section and other is development section. In this architecture two separate cartridge will be used for each colour. Each cartridge can be replaced separately.
4 Vertical EBT: EBT means Electrostatic Transfer Belt. It has a simple paper path.and transfer the image directly on paper by using an EBT. This printer gives fast outout and best quality print.
