Section 6.1).
• The Printhead temperature is too high. Use your application
software control to adjust the burn time and/or heat setting.
• Incorrect ribbon/paper combination being used. Be sure to
use the correct ribbon type.

• The labels are incorrectly loaded, see the loading
instructions on the inside cover of the Printer, or Section
1.6.1.

software, or simultaneously press the cancel and pause
switches, or turn the Printer ‘off’ and then ‘on’ again.
• The Printer is set for 8-data bits but the transmitting device
is set for 7- data bits (or vice versa). Check the current data
