Troubleshooting Scan and Copy Issues
Clipping or incorrect scale factor
when down-scaling in copies and
prints
When doing copies or prints (from USB, Embedded Web Server,
or printer driver), the scaling setting is available with various
possible options. If experiencing problems related to border
clipping, or it seems that the print has lost the scale-factor
adjustment, read this section select the best value for future
scaling settings.
•
Custom (Precise scaling):
The content of the original image is
scaled by the percentage factor that you select. For example, in
an original CAD image with a 1:100 scale, if you select a scale to
50%, the printed plot will have an accurate scale of 1:200.
Regardless, in down-scalings, when selecting a fixed percentage,
some clipping of the marginal content of the plot may occur, as it
is impossible for the printer cannot print up to the borders of the
paper.
•
Fit to (Scale to fit into page size):
The content of the original
image is scaled by the percentage necessary to make sure that
all content is correctly printed and no clipping occurs. Regardless,
in down-scalings, when selecting fit to page, the scale-factor
adjustment may not be an integer divisor of the original. For
example, in an original CAD plot with a 1:100 scale on A2 paper
size, if you select a scale to fit on A3 paper size, the scaling factor
will not be exactly 50% and the scale of the printed plot will not be
1:200 exactly. However, the plot will be printed completely without
clipping any content.
Incorrect edge detection, mostly
when scanning tracing paper.
Tracing or translucent papers can be scanned with good results,
although totally transparent papers are not supported. However,
the resulting image may have extra margins or some clipping of
the content in some situations when paper edge detection is not
accurate. This may also happen when scanning plain paper if the
glass plate is dirty. To avoid these undesired effects, follow these
recommendations.
• Carefully clean the scanner’s glass plate and the original to be
scanned with a cloth.
• Turn the original 90 degrees if possible and re-scan it
Note:
Remember to select
Translucent
as the paper type at the
scanner if your original is translucent.
• If the problem persists, calibrate your scanner, and re-scan your
original afterwards.
• If the problem persists with translucent paper, attach a sheet of
white paper to the back of the original to be scanned.
