6. Mechanical Function
Carriage Drive Gear
6.1 Carriage Drive System
The Carriage Drive System uses a pulse motor to
move the carriage 1/60 inch per single drive pulse.
The carriage slides on the carriage guide plate and
carriage shaft when spacing to the right and left.
6.1.1 Power Transmission Mechanism
The rotation of the carriage motor is transmitted to the
carriage through the carriage drive gear. The timing
belt fixed under the carriage is looped around the idle
pulley and carriage drive gear. This causes the
carriage to move left and right along the carriage
shaft. The timing belt is given proper tension by the
idle pulley tension spring hooked between the pulley
bracket and chassis.

6.1.2 Print Timing
Print timing for pica (1/60 inch) and elite (1/72 inch) is
generated by a software operated timer. Refer to
"Carriage Motor Drive Block" page 33.
6.1.3 Home Position Detector Mechanism
The home switch is a leaf switch located at the far left
of the printer. Its function is to notify the CPU of the
carriage reference position. During spacing operation,
when the carriage approaches the left margin, the
barrier tab, mounted under the carriage, actuates the
home switch, generating the signal and indicating
carriage position to the CPU.
