Here are some label printer maintenance tips.

1. Clean the print head and platen roller

The print head is not only the most important part of any label printer but it is also very delicate. The platen roller sits directly underneath the print head. It is recommended that you clean both components each time you change ribbons or label rolls.

Please do not touch the print head directly as oils and other contaminants on your hands may affect it negatively. Use a suitable cleaning liquid for thermal label printers (> 90% Isopropyl alcohol) and apply with a lint-free and non-abrasive cloth.

2. Clean the exterior and interior area of your thermal label printer often

To keep your thermal label printer running optimally, remember to clean the interior and exterior of the printer. When these areas are dirty, the chance of debris getting into the wrong area is increased.

To clean the exterior surfaces of the printer use a lint-free cloth. Do not use harsh or abrasive cleaning agents or solvents. If necessary, a mild detergent solution or desktop cleaner may be used sparingly.

3. Choose qualified ribbon

If you are using a ribbon in your thermal label printer , be sure that it is a good quality ribbon. Lower cost ribbons are often not manufactured to the exact wax and/or resin specifications of your printer and could cause a wax build-up on the platen.

Wax build-up can cause poor print quality resulting in barcode reliability issues.

4. Perform a pause self test

Missing print outputs and streaks when printing may indicate a defective or clogged print head. Try cleaning the print head and perform a PAUSE self test.

Consult your user manual for the exact instruction. The self test will print a nozzle check pattern to see if the print head is capable of printing across the entire label width. If it verifies a printer problem, it may be necessary to replace the print head.

5. Set up a maintenance contract for your thermal label printer

Maintenance contracts can be tailored to your individual needs and offer calculable costs for extended services.
