Chapter 2 Principles of Operation
2.2.03 Ribbon Drive Mechanism
The ribbon drive mechanism moves the ribbon in synchronization with the space motor operation.
The ribbon drive mechanism consists of the items listed below.
Ribbon Drive Assembly
Ribbon Cartridge
Ribbon Cartridge
An endless ribbon with a single direction feed is used. Ink is supplied from an ink tank, which is contained
in the ribbon cartridge.
Ribbon Feed Operation
The rotation of the space motor is transmitted to the drive gear in the ribbon cartridge through the ribbon
feed gear assembly, thereby feeding the ink ribbon.
The feed direction of the ribbon is maintained by switching the rotational direction of the gears in the
ribbon drive assembly. This ensures unidirectional ribbon movement when bi-directional printing is used.
