kg Kilogram(s). Kg Kilogram(s). LAN Local Area Network. lb Pound(s). LED Light-Emitting Diode. Line Sensor Carriage LED. Main PCA The printed circuit board contained in the Electronics Module. m Meter(s) Margin Part of the media on which the plotter is incapable of printing. Mbyte Megabyte. Media (Used instead of medium.) The material on which the graphics are plotted: paper, translucent material, vellum, film, or special paper. Media Axis The axis along which the media moves. (X-axis; paper axis.) Media Jam A situation in which media becomes blocked in the plotter mechanisms. Media-jam Lever Pinch-arm lever. Media-length Calibration Media-sensor calibration. Media-sensor Calibration Media-length calibration. mil 1/1000 of an inch. Minimum Pass Time The time necessary for ink to dry sufficiently before the plotter can place more ink adjacent to it. MIO Modular Input/Output. mm Millimeter(s). Monitor Mode Service monitor. MS-DOS MicroSoft Disk-Operating System Nesting Placing two or more images side-byside to avoid wasting the media. No Negative Motion An RTL command that indicates to the plotter that it will receive all data already in the order in which it should be plotted. Nozzles 240 holes in the printhead through which ink is fired onto the media. Off-axis Ink System A system whereby ink is pumped to the cartridges from a reservoir that does not move with the carriage. PAL Programmable Array Logic. Palette A set of pens for which width and % shading are defined using the setup sheet or the graphics software. Paper Axis Media axis (X-axis). Parity An error-checking method for information transfer between a computer and a peripheral device. Parity is used to check the accuracy of binary data. Pass A movement of the carriage from left to right, or from right to left, as it plots the graphic. Pass Advance The distance that the media advances between carriage passes. PC Personal Computer. PCA Printed Circuit Assembly. Pen 1. Even though the inkjet plotter has no physical pens, the lines it draws match the attributes for pens numbered 1 through 8 in the application software. (See also "palette.") 2. Sometimes used instead of "print cartridge." Pinch-arm Lever Pinch-wheel lever, mediajam lever. PJL Printer Job Language, developed by Hewlett-Packard to give software applications more job-level device control and to provide device status information to the application.
