Motor, Pulleys, and Belts
The stepper motor drives both the platen roller and the transfer ribbon
rewind unit via a series of belts and pulleys.
As a standard, the stepper motor has double pulleys to be prepared for the
installation of an optional rewinder (as described in “Rewinder Module”
on page 57). The motor and belt are available as spare parts. The tension of
the belt is automatically adjusted by a sprinkled arm-and-wheel
arrangement attached to the center section.
The stepper motor module is attached to the bottom plate using four
screws. The motor is connected by a four-wire cable harness to connector
P31(“MOTOR”) on the main board.
