   • Ensure that all components are properly installed and securely tightened to prevent leaks or malfunctions.

5. Performing Test Prints:

   • After cleaning and maintenance, reinstall the printing head and ink cartridges/reservoirs following the manufacturer's instructions.
   • Perform test prints to verify that the date coder is functioning correctly and producing clear, legible codes.
   • Adjust any settings or parameters as needed to optimize print quality and consistency.

6. Documenting Maintenance:

   • Keep a record of the maintenance activities performed, including the date, details of cleaning and inspections, and any parts replaced.
   • Note any issues encountered during maintenance and any corrective actions taken to address them.
