Features
1. Small-size, high-speed monochrome printer
This equipment has a compact body that realizes high-speed print of 25 ppm (A4) / 26 ppm
(LTR).
2. Automatic duplex print
Automatic two-sided printing is available with standard equipped duplex unit.
3. Reduction in standby time and energy consumption
This equipment employs on-demand fixing where the heater activates only during printing,
resulting in a reduction in standby time and energy consumption on this mode.
4. Realization of noise reduction and stable image quality
This equipment employs a belt drive method for transmitting the drive of the main motor.
This enables lower noise and more stable image quality compared to the conventional gear
drive method. (See NOTE)
5. Improved Usability
In this equipment maintenance (jam removal, replacing the cartridge) can be performed by
accessing one point of the delivery tray.
Note:
Changing the drive method from gear to belt reduces uneven pitch due to varied
rotation speed of the photosensitive drum, which realizes stable image quality.
