• Lines are not visible
If the file to be plotted is in a HPGL or Calcomp format, the
color can be set too light or the pen widths are too small.

• Printout plotted on an unexpected medium
The plotter can sometimes print on another roll that you ex-
pected, although you entered the default values correctly.
This can be caused by the following:
1. RW-470 PLOTBASE has a plot logic, which is instructed

This can be caused by the following:
1. RW-470 PLOTBASE has a plot logic, which is instructed
to „waste“ as little paper as possible when selecting the
roll, to print as quickly as possible (preferred print direc-
tion in landscape format).
roll, to print as quickly as possible (preferred print direc-
tion in landscape format).
2. As the roll sizes in RW-470 PLOTBASE must be fixed
without variances, it is necessary to print on a larger roll
even if a drawing is only 0.1 mm larger than the roll se-
lected by you. This can e.g. be the case if unfavorable
pen widths or scaling have been selected. There are
three possible ways to solve the problem:
a) Scale the drawing to e.g. 99 %,
b) Increase the setting for the number of “step

c) Use a thinner pen width for the drawing frame.
• Quality loss
Especially in photos and drawings with lots of gray scales,
scaling can lead to a loss of quality. This is because the CIS
element [Contact Image Sensor] in the scanner only divides
all gray scale values into black and white due to the black-
white threshold value and gray scale values can therefore
not be scales with the drawing.
