2.1 Configuration
This printer mechanism is composed of the following components.
Printer mechanism

Timing detector
Home position detector
Paper out detector
Ribbon position detector (MP216)
Paper feed mechanism
Ink ribbon wind mechanism
Print head unit

2.2 Principle of Operation
2.2.1
Drive
This printer mechanism moves the print head, paper feed, ribbon shift (MP216) and feeds 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
Ribbonfeed
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
Paperfeed
Paper feeding is done by the rotation of the motor turns on the line feed solenoid to activate the
spring clutch and to turn the gear.
2.2.6
Ribbonshift
In case of MP216, make the motor rotate to make electricity flow to the ribbon solenoid so that
the spring clutch operates and so that the cam gear rotates half a turn, and then change to a ribbon
of another color.
