Any of these suggestions/resolutions can impact printing or print quality and are provided in one Solution for your convenience.

Cleaning the Printhead

Media and Ribbon Combination.

The type of labels and ribbon (if used) affects the quality of the print. Consult with your supplier for details. Verify you are using a properly matched combination of labels and ribbon for your application.

Test Print 

A printer self test label can be used to determine if the given print quality issue is seen from the printer itself and to test any changes made on the printer as you are troubleshooting the issue.

The printer operates at the selected speed in terms of inches/mm per second.  Because print quality is affected by print speed, media, ribbon ( if thermal transfer ), and printer operating modes, it is important to run tests for your application to choose the optimal print speed setting.  Slowing down the print speed can also help if the print is too light.

Adjusting printer darkness

The darkness level can be set directly on the printer from the LCD Display or through commands sent by the user or from the driver/application.  Read More>>

Note: Keep in mind that the software and driver settings can override the darkness level you set on the printer using this method.

Power Supply

Assure you are using the correct power supply. Use of a power supply that does not meet the printer requirements will result in unacceptable printer function. 24 Volts 100 Watts required
