2 CHAPTER OPERATING PRINCIPLES
EPSON FX-890/2190 Revision B 2.1 Overview C524 PSB/PSE/PSH Board This printer is divided into several main components for easy removal and repair.
EPSON FX-890/2190 Revision B 2.1.1 Printer Mechanism 2.1.1.2 Paper Feed Mechanism This printer mechanism consists of Printhead, Paper feed mechanism, Carriage movement mechanism, Tractor feed mechanism, Platen gap adjustment mechanism, Ribbon feed mechanism, PF motor, CR motor, detectors, and so on. The paper feed mechanism picks up paper and transports it to the printhead, then ejects the paper step by step or continuously driven by the PF motor.
EPSON FX-890/2190 Revision B 2.1.1.6 Ribbon Feed Mechanism 2.1.1.7 Sensors The CR motor drives the ribbon feed mechanism via the timing belt. The ribbon feed mechanism has the sun and planetary gear system. No matter the carriage unit is driven left and right, the ink ribbon is driven in one direction. Table below lists the sensors of this printer. Tractor PG Detector Table 2-1.
