2.1.1 Printer Mechanism

NX100 series and NX110 series printer mechanism consists of printhead, carriage
mechanism, paper loading mechanism, paper feed mechanism, and ink system.
As the conventional models, NX100 series and NX110 series are equipped with two
DC motors; one is used to drive the paper loading, paper feed mechanisms, and the
pump mechanism that includes the carriage lock mechanism, and another one is used to
drive the carriage mechanism. A paper is fed from the rear ASF unit by means of the
LD roller and Retard roller and ejected to the front tray.
