Cleaning

Exterior Cleaning

Clean external surfaces to remove dust and residue.

Calibration

Media Calibration

Media calibration aligns label feeding and positioning.

Perform media calibration:

• After replacing labels or ribbon

• If feed alignment issues are observed

For calibration procedures, refer to Calibrating the SATO CL4NX.

 

Print Head and Media Alignment

Print head and media alignment affects print consistency.

1. Verify that labels and ribbon are seated in the media guides.

2. Verify that the RFID antenna assembly is fully latched.

3. Confirm that the print head is locked in position.

Adjust alignment if mispositioning is observed.

 

Replacing Consumables

Replacing the Thermal Ribbon

Replace the thermal ribbon when depleted or damaged.

1. Remove the depleted ribbon.

2. Install compatible replacement ribbon.

3. Verify correct ribbon orientation and tension.

For supported supplies, refer to the Label and Thermal Ribbon Ordering Guide.
