Default Settings

To restore the default settings of the plotter, press and hold the menu button (button 3) while powering the plotter on. The display will briefly show “dF” during the boot up sequence, indicating that the default menu items have been loaded.

Testplot

This function produces approximately six inches of plot in a checkerboard and dither pattern in Bimodal mode. Generating a test plot while the plotter is set to grayscale mode will result in a grayscale plot corresponding to the number of gray levels selected at the time. This enables the user to verify that the plotter is creating a plot image, feeding the paper correctly, and that contrast levels and media settings are acceptable. The test plot will use the current menu settings to generate the image.

1.Press Button 1 to put the plotter into OFFLINE mode.

2.Press Button 3 once. “tP” is displayed.

3.Press and hold Button 3 until the display flashes: The test plot will be generated.

Contrast

The contrast function adjusts the density of the output. Settings range from C 1 to C 8. Settings are relative values: C 1 is the lightest,

C4 is normal, C 8 the darkest.

After performing a test plot or plot job, determine if the contrast is acceptable. If the output is extremely dark, very faint, or irregular, first check that the media setting is correct (see “Media” section of this chapter).
