Description
The movement distance of the media changes subtly depending on the media's thickness and the temperature
of the dryer. When the movement distance becomes discrepant, horizontal stripes are more likely to occur
during printing. We recommend that you make corrections to match the media you are using and the set
temperature of the dryer. Repeat the process of printing a test pattern and entering a correction value several
times to find the optimal value.
Depending on the software RIP you are using, you can also make this setting in the software RIP (by, for exam-
ple, choosing the media type). When you have made the setting in the software RIP, the software RIP's setting
is used and the printer's setting is ignored.
