General Guide for the Preset Temperatures

The optimal temperature for the media heating system varies according to such factors as the type of media and
differences in the print mode. 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 software RIP, adjusting this may yield better results. If
problems such as smudging persist even after raising the temperature, try reducing the amount of ink.
Use at an ambient temperature of 20 to 32ºC (68 to 90ºF).
If the machine is used at an ambient temperature less than 20ºC (68ºF), then depending on the type or width of the
media, wrinkling or temperature-caused unevenness may occur. To obtain stable printing results the machine should
be used at an ambient temperature of 20 to 32ºC (68 to 90ºF).
