Chapter 2 Operation
General Guide for the Preset Temperatures
The optimal temperature settings vary according to the type of media, differences in the print mode, and other
factors. Use the following as a general guide and adjust accordingly.
General Guide for Adjustment
Preheater
Set this to a temperature that is the same as or lower than the temperature of the print heater.
You use the preheater mainly to heat media gradually. This is because media becomes more likely to shrink or
wrinkle if heated suddenly.
Print heater
You use this mainly to improve ink adhesion and inhibit smudging.
If the ink forms lumps or smudges, raise the temperature. Note, however, that a temperature that is too high may
degrade the media or cause it to wrinkle.
Dryer
When ink drying is poor, raise the temperature. Note, however, that a temperature that is too high may degrade
the media or cause it to wrinkle.
The relationship between the print mode and temperature
If smudging or poor drying occur even after raising the temperature, try using a print mode offering higher image
quality. Conversely, when you want to use a faster print mode, raise the temperature.
Amount of ink
When you change the amount of ink using the settings for your RIP program, adjusting this may yield better
results. If problems such as smudging persist even after raising the temperature, try reducing the amount of ink.
Examples of Preset Temperatures
➢
These are only rough estimates. Make adjustments to match the media you're using.
➢
Using the heating devices does not necessarily make it possible to apply ink to every kind of media. Be sure to test
in advance.
➢
Results may vary greatly depending on the print mode and other factors. Make settings suited to the media.
➢
When suggested settings for temperature, print mode, and other values are given, use the suggested settings.
