2. CONSTRUCTION

2.1 Configuration

This printer mechanism is composed of the following components.

Printer mechanism Drive unit, gears, and carriage unit

Detectors Timing detector

Home position detector

Paper out detector Paper feed mechanism Ink ribbon wind mechanism Print head unit Frame unit

Other

You can also use 1.75 inch (45 mm) width roll paper by removing the paper guide B and attaching the optional guide.

2.2 Principle of Operation

2.2.1 Drive

This printer mechanism moves the print head, feeds paper and feed ribbon with the motor.

2.2.2 Print head movement

The rotation of the motor is transmitted to drive shaft through the reduction gears. The carriage makes lateral reciprocal movements along a groove that is carved on this drive shaft, consequently moving the print head.

2.2.3 Print timing

Printing is done when the timing signal is generated synchronized with the rotation of the motor, based on the home position signal.

2.2.4 Ribbon feed

The ink ribbon is housed inside a ribbon cartridge in endless fashion. A ribbon feed roller is turned by the rotation of the motor whereby the ink ribbon is wound up.

2.2.5 Paper feed

Paper feeding is done by the rotation of the stepping motor.
