The drying fan assembly has been designed to keep power consumption down to a minimum by only activating the amount of fans that are required to dry the size of media that is loaded on the printer.

On the NovaJet 750 printers a thermal media drying assembly is used instead of the fan assembly as on the other models.

The drying assembly can be operated with or without the heating elements being turned on.
