2.1 Overview
This section describes the operating principles of the Printer Mechanism and Electrical
Circuit Boards of Stylus C110/C120/D120.
Stylus C110/C120/D120 employs a newly developed printer mechanism. The
following sections explain about the major components of the new printer mechanism.
2.1.1 Printer Mechanism
Stylus C110/C120/D120 printer mechanism consists of printhead, carriage mechanism,
paper loading mechanism, paper feed mechanism, and ink system.
As the conventional models, Stylus C110/C120/D120 is 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.
