6. To set a printing delay, press the Printing Delay option in the Media Settings menu. The Printing Delay screen appears. Increase the printing delay to allow more heat to dissipate from the media between print passes. Decrease the delay to increase throughput. 7. Increase or decrease the delay by pressing the ▲ or ▼ keys. 8. Press Proceed (►) to save your changes, or Cancel to discard them. 9. To set the lamp mode, press the Lamp Mode option in the Media Settings menu. The Lamp Mode screen appears. 10. Configure the UV lamps operation by touching the option for the leading and trailing lamps. Buttons will appear or disappear to present only valid combinations (for example, you cannot set both lamps to Shuttered). ● For standard media listed in the Media Wizard, leave the lamp settings at their default values, then adjust as needed. ● Faster print modes require higher lamp settings to ensure sufficient curing. ● If the ink is not curing, increase the setting. The lamps will gradually lose curing effectiveness, so increasing the setting eventually may become necessary. ● If the media is wrinkling or warping from the heat of the lamps, lower the setting. 11. To set the aperture settings, press the Shutter Aperture option in the Media Settings menu. The aperture settings screen appears. 12. Adjust the shutter apertures, or press Proceed (►) to continue. You can select the aperture (opening amount) for each shutter, and/or completely close one of the shutters, during printing. This enables you to reduce the warping of rigid media by reducing the amount of light and heat emitted by the lamps. The aperture can also be set by touching the UV lamps info panel. The UV lamp shutters are vertical when completely opened, and rotate to change the aperture. An aperture setting of 0 degrees is completely open; 20 degrees is half open, "Closed" is completely closed. You cannot set both shutters to closed while printing. During printing, the lamp icons on the control panel are dynamically shaded to indicate the aperture setting. The icons will change as the carriage direction changes if the leading and trailing aperture settings are different from each other. 13. Press Proceed (►) to save the settings and return to the Front Page, or Cancel to restore the previous print mode settings. Equivalent print modes From the standpoint of UV curing and temperature, all print modes fall into one of five print speed groups: A, B, C, D, or E. If you change the Printing Delay, Lamp Mode, or Shutter Aperture for any print mode, the changes apply to all print modes within that group. The group for each print mode is shown in the Media Settings screen. The following table shows the print modes by print speed group.
