4.8.1 Stepper Motors
SmartDate 5 uses three stepper motors, one to drive the carriage for the
printhead module/shuttle and two for control of the ribbon.
The position of the stepper motors is the same for all models of the SmartDate 5
printer.
The stepper motors are six wire motors connected in a unipolar configuration.
The motors are connected to the printer board via 6-way 2.54 mm Molex KK
connectors.
Connection points:
• X2 - Carriage Motor
• X4 - Ribbon motor 1
• X7 - Ribbon motor 2
When the Combined printer is in Intermittent mode the printhead carriage motor
steps are in direct relationship to the linear movement of the printhead.
With Continuous versions of the printer the printhead carriage has no linear
motion during printing.
The ribbon motors steps are configured according to data from the Ribbon roller
sensor, Ribbon tension sensor and Encoder if being used.
