Checking and adjusting after the installation

Test print checking

1. After loading the media and ribbon, close the print head and top cover. Then power on the product.
   
2. Perform a test print and check the following items:
   • Check the dispense operation to make sure that there is no slack on the liner.
   • Check the dispenser sensor to ensure that it can sense the label.
     • Before the label is removed from the dispenser bar, the “waiting for media removal” status icon is shown.
     • When the label is removed, the product continues to print the next test print and stops for label removal.
       
   • Check the media stop position to ensure accuracy.
     • The regular position is to let the label stay about 2.0 mm (0.08″) on the liner.
     • If the stop position is incorrect, adjust the offset value on the test print screen.
     • Refer to Section 4.6 Adjusting the Media Stop/Cut Position for detailed adjustment instructions.
       
   • Check the liner rewinding to confirm that the liner is rewound correctly (for liner rewinder models).
   • Check for media meandering to verify that the media feeds straight without slanting.
     • If the feeding path of the label or liner is slanted, adjust the slope angle of the dispenser bar.
     • Loosen the screw, adjust the dispenser bar, and then tighten the screw to secure the new position.
