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.
Test plot
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,
C 4 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).
