CHAPTER I GENERAL 1. FEATURES A. This high-speed, non-impact (low-noise) printer is based on electrophotography, electronics and laser technology. B. The printer is compact and easy to carry. The internally-storable, front-loading paper cassette enables you to save an occupation space for the machine; the printer can now be installed in a smaller place. C. The charging roller, developing cylinder, photosensitive drum and cleaner of the printer are combined into a single assembly called an "EP-ED cartridge". The cartridge can be replaced by the user when necessary without a need of service call. High printing quality is maintained by a simple cleaning procedure. D. Laser beam safety is designed into the printer. The printer is approved by the US Center for Devices and Radiological Health (CDRH). E. Paper can be fed in two ways, by the multi-purpose paper feed tray and paper cassette. F. Maintenance is easy with print component units which are directly detachable, and they require no adjustment after reassembly. 2.
