Scaling
The scaling function stretches or shrinks the plot over a 36-inch length of plot with settings being S0 through SE.
The default setting is (S2). To determine if scaling is needed, plot a job of a known length and measure it.
Adjustments can be made to the
scaling in increments of + or - 1/16-inch over 36 inches of plot. S0= no scale, SE = +/- 14/16” over 36 inches of
plot.
Note: Positive or negative scaling is selected through the Emulation menu setting.
Emulation (vertical resolution)
The emulation function adjusts the vertical resolution of the plot (along the media length). The settings are P0, n0,
P3, and n3. P0 and n0 are used with 200 scans/inch of plot data. The default setting (P3) is 203 scans per inch
(equal to 203 dots per inch- dpi). P3 and n3 are used for 203 scans/inch of plot data. P and n stand for Positive
and negative scaling for the scaling menu. If n is selected, the scaling factors are from no scale to -14/16” over
36” of output plot. If P is selected, the scaling factors are from no scale to +14/ 16” over 36” of plot.
Note that the horizontal resolution is determined by the printhead dot density, which is 203 dpi. The plotter can
emulate 200 dpi vertical resolution (E0 and n0 settings), to match the rastered host data (for Imperial units).
Form feed length
The form feed length function adjusts the distance that the media is advanced in off-line mode and when a remote
function is sent. To form feed media, put the plotter in offline mode and press the FORMFEED/ADVANCE button
without holding .
Menu settings are: F2, F4, F8, tF, PF.
F2, F4, F8 cause 2”, 4”, or 8” of media to be advanced upon a formfeed. If a TOF mark is detected before the
formfeed is completed the plotter will stop upon detecting the mark, or to what the PF setting is.
tF results in the plotter advancing up to 18” while detecting for the Top of Form mark on fan fold media. The top-
of-form setting (tF) allows the plotter to detect top-of-form marks. These marks signal the plotter to stop the form
feed at a consistent distance from the perforated edge of the paper.
PF - Programmable advance past Top of Form- This feature allows the V8.5e to line up with the beginning of
pages when a media whose TOF marks do not meet the V8.5e specifications.
NOTE: iSys recommends only the use of approved media in the V8.5e which has been qualified to increase plotter
life and produce higher quality plots.
Once the PF feature is selected in the menu, the V8.5e will detect the media TOF mark and continue to advance
the media by the amount programmed when a formfeed or end of transmission is commanded.
