OUTLINE OF ASSEMBLY OPERATION
NP -70
The NP-70 is equipped with two blower assemblies and one fan assembly. The Suction
Blower Assembly within the Copy Conveying Assembly, together with the Air Input Blower
Assembly on the copier rear, operates to create an air flow through the interior of the copier.
This air flow results in proper separation of the paper from the drum and ventilation of dis-
persant fumes resulting from the fixing process.
The Fan Assembly located at the right-front end of the copier operates when temperatures
are above 60°C. This operation is designed to prevent excessive dispersant evaporation due
to heat within the copier.
