Ribbon Drive - Oki Pacemark 4410 Service Handbook

2.2.4 Ribbon drive (See Figure)
The ribbon feed mechanism feeds the ink ribbon and functions by driving the ribbon motor (pulse
motor).
(1) Ribbon cartridge
This has a mechanism of capable of printing clear characters at all times by using a one-way-
feed endless ribbon.
(2) Feeding
The ribbon feeding mechanism starts running regardless of whether the printer is printing or
not, and stops at the same time when the spacing motion stops.
When the ribbon motor is driven, the rotational force is transmitted to the drive roller in the
ribbon cartridge through ribbon feed gears, and the ink ribbon fed.
