Ribbon Drive Mechanism

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.
