5.8 Printhead Module / Shuttle Carriage Drive Problems 
A stepper motor, drive belt and linear slide are used to move the Printhead 
module / Shuttle carriage. 
The carriage drive may stall when the SmartDate 5 is under excessive load.
If the carriage does not drive, check the following:
• Is the ribbon is loaded correctly?
• Is there any mechanical interference stopping the carriage moving?
• Check the condition of the drive belt and drive pulleys.
• Check the condition of the linear slide. 
• With the power to the unit turned off, is the Printhead module free to move 
along the slide?
• Are the stepper motor connections correct and secure.
• If the fault persists, replace the Printer PCB.
