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 you are experiencing problems related to border clipping, or it seems that your print has lost the
scale-factor adjustment, read this section carefully in order to select the best value for the scaling
setting in future jobs.
●
Output scale: Custom (Precise scaling):
In this case, the content of the original image is scaled
by the percentage factor that you have selected. For example, in an original CAD image with a
1:100 scale, if user selects scale to 50%, the printed plot will have an accurate scale of 1:200.
Nevertheless, in the case of 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 to print up to the borders of
the paper.
●
Output scale: Standard sizes (Scale to fit into page size):
In this case, the content of the original
image is scaled by the percentage necessary to make sure that all the content is correctly printed
and no clipping occurs. Nevertheless, in the case of 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 user selects 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.

not supported.
