Table B-1 Glossary of terms (continued) Duty Cycle Duty cycle is the page quantity which does not affect device performance for a month. Generally, the device has the lifespan limitation such as pages per year. The lifespan means the average capacity of print-outs, usually within the warranty period. For example, if the duty cycle is 48,000 pages per month assuming 20 working days, a printer limits 2,400 pages a day. Eco The Eco feature allows you to save print resources and results in an eco-friendly printing. Emulation Emulation is a technique of one printer obtaining the same results as another. An emulator duplicates the functions of one system with a different system, so that the second system behaves like the first system. Emulation focuses on exact reproduction of external behavior. This is different from simulation, which concerns an abstract model of the system being simulated, often considering its internal state. Erase backside image Prevents copying the original's image shown through on the back side. Erase edge Allow the erasing of spots, drill holes, fold creases and staple marks along any of the four edges of a document when making a copy. Ethernet Ethernet is a frame-based computer networking technology for local area networks (LANs). It defines wiring and signaling for the physical layer, and frame formats and protocols for the media access control (MAC)/data link layer of the OSI model. Ethernet is mostly standardized as IEEE 802.3. Ethernet has become the most widespread LAN technology in use during the 1990s to present. FDI Foreign Device Interface (FDI) is a card installed inside the device to allow use of a third-party device, such as a coin operated device or a card reader. Those devices allow the pay-to-print service on your device. Filing Policy Automatically renames or overwrites when the USB memory device has a file with the same name. You can choose the policy for generating file names before you proceed with the scan job through the USB memory device. FTP A File Transfer Protocol (FTP) is a commonly used protocol for exchanging files over any network that supports the TCP/IP protocol (such as the internet or an intranet). Fuser Unit The fuser unit is part of a laser printer that fuses the toner onto the print media. It consists of a heat roller and a pressure roller. After toner is transferred onto the paper, the fuser unit applies heat and pressure to make sure that the toner stays on the paper permanently, which is why paper is warm when it comes out of a laser printer. Gateway A connection between computer networks, or between a computer network and a telephone line. It is very popular, as it is a computer or a network that allows access to another computer or network. Grayscale Shades of gray that represent light and dark portions of an image when color images are converted to grayscale. Colors are represented by various shades of gray. Halftone An image type that simulates grayscale by varying the number of dots. Highly colored areas consist of a large number of dots, while lighter areas consist of a smaller number of dots. HDD Hard Disk Drive (HDD), commonly referred to as a hard drive or hard disk drive, is a non-volatile storage device which stores digitally-encoded data on rapidly rotating platters with magnetic surfaces. ID copy Prints two-sided originals on one sheet of paper. The device prints one side of the original on the upper half of the paper and the other side on the lower half of the paper. This feature is helpful for coping a small sized item, such as a business card. IEEE The Institute of Electrical and Electronics Engineers (IEEE) is an international non-profit, professional organization for the advancement of technology related to electricity. Imaging Unit Imaging unit consists of the OPC drum unit and the developer unit. Intranet A private network that uses internet protocols, network connectivity, and possibly the public telecommunication systems to securely share part of an organization's information or operations with its employees. Sometimes the term refers only to the most visible service, the internal website. IP address An Internet Protocol (IP) address is a unique number that a device uses in order to identify and communicate with other devices on a network utilizing the Internet Protocol standard. 160 Appendix B Glossary
