Power Supply
An auto8ranging power supply is located in the electronics module. (Specifications ' chapter 1, •Power Requirements.")
The primary side of the power supply contains rectified line W R N I N G voltage that can be lethal when touched even if the ON/OFF
switch is OFF
In any case you should not need to open the electronics module It is one exchangeable part
Water Condensation
In humid environments, water may condense on the side8plates. A wick attached to the underside of the right side8plate routes water drops away from the main8PCA electronics.
Memory Usage
It is difficult to calculate the amount of plotter memory needed to plot a drawing of any given file size. Memory is used, not just to hold the input data, but also for system overhead, processing work8space, and storage of the internal representation of the plot. Some types of graphics require relatively large amounts of memory. Examples are wide lines, raster fill patterns, polygons, and user8defined lines.
Plot Orientation
The output orientation of the drawing also has an impact on memory usage. Compare a plot of horizontal lines with one of vertical lines. Lines plotted parallel to the carriage axis take up considerably less memory than those plotted perpendicular to it. The plotter builds graphic display objects on a swath8by8swath basis. A horizontal line can be contained in one swath. A vertical line spans many swaths and therefore requires more entries in the plotter's internal display list.
Raster Image Processor
The raster transfer language (RTL) provides a solution to insufficient memory on the plotter. When all the data is sent to the plotter in the order left8to8right and top8to8bottom, the plotter is able to plot the data as it receives it. For this to happen, software (a raster8image processor) in the computer must first rasterize all the data. The software issues a command (referred to in RTL as no negative motion) telling the plotter that it will not receive data for any media location on which it has already plotted.
The use of no negative motion is called flow mode. Data flows through the plotter without being stored in a display list, so the size of the file that you can send is almost unlimited.
