Installation & Usage Notes
-
Mount the printer in a stable, vibration-minimized location and ensure the unit is level for optimal paper feeding.
-
Use recommended thermal paper rolls (e.g., 112 mm width) and ensure that the next roll is loaded correctly to prevent printing errors.
-
Ensure communications cable (serial or parallel) is correctly connected and configured in the message-system settings.
-
For integration with NAVTEX/DSC systems, verify the printer’s online/offline status and feed mechanisms work during message receipts.
