2. Check the settings for text report printing in the PAGE SETUP
window (see Document page setup, page 11). Select the tab
Documentation
and set the
Report type
to
All
if you want to print
the whole text report.
Curves are missing in curve printing
1. Check the color settings for curve lines (some colors may
vanish on a black and white printer). Select black or dark col-
ors as default in the
GENERAL PREFERENCES window (see
Settings, page 19) or OPTIONS window (see Display of curves,
page 14).
2. Check the curve subwindow in the
MAIN WINDOW
. If no curve
is visible, the scaling may be wrong. Adjust the scaling in the
OPTIONS window (see Scaling of curve axes, page 18) or re-
set the curve window to the default scale by pressing the
key or select the
Set Default Scale option of the context
sensitive menu.
3. If the curve is not visible with default scale settings, change
the x and y axes scales to Auto in the OPTIONS window (see
Display of curves, page 14).
4. Since the changed scaling settings are not stored in the da-
tabase, you should correct the wrong scaling settings in the
746 VA Trace Analyzer. For this, send the selected determi-
nation to the 746 VA Trace Analyzer and check the Dis-
play/Plot parameters for segments or substances. Correct the
scaling to the desired values and send the determination
back to the VA Database.
Curves in custom reports are missing in printing
1. Check the color settings for curve lines (some colors may
vanish on a black and white printer). Select black or dark col-
ors as default in
OPTIONS window (see Curve fields, page 64).
2. If the curve is still not visible, send the selected determination
to the 746 VA Trace Analyzer and check the Display/Plot pa-
rameters for segments or substances. Correct the scaling to
the desired values and send the determination back to the VA
Database.
Curve and axes lines are very thin
This problem may occur with printers with a high graphics
resolution. Reduce the graphics resolution on your printer
(e.g. to 600 dpi or 300 dpi).
