Miscellaneous Problems
The following information identifies some possible printer problems and what might be their cause.
∙Problems with
∙If information downloaded to the printer memory is lost after the printer is powered off (lost data includes configuration setting changes reverting to their factory defaults when power is cycled), the lithium battery may be bad.
∙The appearance of long white streaks in printed labels indicates a dirty printhead or possible printhead failure.
∙If you have problems with the bezel LEDs or the Feed/Pause button, you may need to replace the bezel PCB assembly.
∙If the printer no longer registers the use of marked label stock, you may need to replace the label mark sensor.
∙Light print on one side of a label can occur if the printhead is not making even contact with the media. This condition can happen with any size media, but is most common when using narrow labels where there is no media between the printhead and the platen roller. Uneven lateral print darkness may be eliminated by adjusting the bias screw.
∙If the printer is no longer sensing when labels have been removed, you may need to adjust or replace the label taken sensor.
∙If the TTR takeup hub fails to roll up ribbon, you may need to replace the upper drive belt and/or the TTR takeup clutch.
∙If a ribbon fault occurs when the printer is in the TTR mode, you may need to replace the TTR encoder sensor.
∙If the liner takeup hub discontinues rolling up liner, you may need to replace the liner takeup (lower) drive belt or clutch.
∙If the platen roller does not turn but the liner drive roller does, you may need to replace the platen roller gear.
∙If none of the rollers turn, you may need to replace the stepper motor.
