If the contrast needs further adjusting, change the contrast setting by starting at the lowest value, adjust the contrast upwards one value at a time, testing after each adjustment. This is particularly important when using lightweight papers or papers with unknown specifications.

CAUTION: Thermal plotting technology involves high temperatures. Incorrect media or contrast settings can damage the printhead or other components and void the warranty. Media damage can also occur.

VORSICHT: Bei der thermischen Plottertechnologie entstehen hohe Temperaturen. Ungeeignete Medien oder falsche Kontrasteinstellungen können den Druckkopf oder andere Bauteile beschädigen und zu Verlust der Garantie führen. Auch können Beschädigungen an den Medien entstehen.

Speed

The speed function adjusts the speed of the plot output. There are four output plot speed settings in the V8.5e: 1.0, 2.0, 3.0, and 4.0 inches per second. The default setting is 1.0 inch per second which produces the highest quality output.

If the plot speed is erratic, or if output quality is unacceptable, lowering the plot speed will result in an improved plot quality. Such problems may arise when data enters the plotter at a slower rate than the plot speed setting. Lowering the output plotting speed enables the plotter to match a lower input data rate and produces a smoother output plot.

When the media setting is film (LF or HF), the plotter speed defaults to 1 inch per second. When Grayscale mode is enabled, plot speed is dependent upon the level of grayscale selected.
