Change the number of bytes per scan (image width) by selecting the “BPS” option in the
appropriate menu. Move up or down the scale by pressing the up and down arrows.
Default “1184”.
Range: 1184 .........594 (400 dpi resolution)
592 .............64 (200 dpi resolution)
NOTE: The selected bytes per scan on the plotter must match the bytes per scan in the
application software that is running on the attached computer host. If the two settings
don’t match the data will look scrambled.
VERT DPI
To change the vertical resolution (dots per inch) select the “Vert DPI” option in the
appropriate menu. Move up or down the scale by pressing the up and down arrows.
Default “200/400”.
Emulations: 200/400 and 203/406 DPI
NOTE: Image must be rastered to the correct resolution or the image scaling will not be
correct.
SCALING
Use scaling to compensate plot length measurement for tolerances in media thickness,
roller diameter and head pressure. Use scaling to compensate for plot length
differences, which are caused by variances in media thickness. Scaling can stretch or
shrink a plot up to one inch.
Default setting is “0”.
Range: +40.... 0.... –40
NOTE: Change the scaling setting by pressing the up or down buttons in the “Scaling”
submenu. The UP arrow button accesses the positive (stretch) increments of 1/40 inch.
TEST PLT
Generates a test plot. Five inches of plot are produced in a checkerboard pattern so you
can see if the plotter is creating a plot image and feeding the paper correctly, and if
contrast levels and media settings are acceptable.
To change from the default TEST PLOT setting of “No”, press the UP arrow
button in the “Test Plt” submenu to display “Yes”, then press the MENU button to
enable the test.
NOTE: Plot creation takes about 4 seconds before plotting. Once plot is complete the
display will go back to “No”.
FF LEN.
Adjust the length of media moved (in inches) if a manual form-feed, remote form-feed, or
an end of transmission (EOT) is detected. The maximum adjustment is 250 in.
Default “5”.
TOF ADJ.
Adjust the distance from the perforation to the “I” mark. This setting is used for
perforated roll or fanfold papers only. This adjustment allows the user to select where
the image will start plotting from the perforation.
Default “0”.
Range: 0......999
NOTE: Adjustments are in 1/16 of an inch increments.
HYST.
Used to adjust image quality at higher speeds. This setting looks at the history of each
dot and decides, through an algorithm, the amount of energy needed.
