As mentioned above the ambient or surrounding temperature does have an effect on the heating of the ink. ENCAD has established that these settings will be adequate for most installations. However, if the printer is in an environment that is hot or that the temperature changes a lot throughout the day, you may have to modify the settings to compensate for your own individual circumstances.
The preheat settings are factory set to aid in the minimizing of ghosting and or ink density issues. With this in mind, lowering the settings could cause improper output to appear.
The settings of the preheat will be dependent upon your environmental condition as well as the type of image and the colors that you are repro- ducing. One particular setting of the preheat may not be correct for every print application.
To check the preheat settings for the problem color (i.e., Cyan dropout problem):
1.From the main menu select Setup Menu.
2.From the Setup Menu select Ink Option Menu.
3.From the Ink Option Menu select Ink PreHeat Menu.
4.From the Ink PreHeat Menu select Cyan - Preheat.
5.Press either Prev Option or Next Option until the value 0 (zero) is displayed.
6.Press OK to accept the selection and return to the Ink PreHeat Menu.
7.Reprint the image to verify problem has been corrected.
