💡 How do thermal transfer heads fail and what prevents premature breakdown?

Swapping to a fresh printhead keeps your labeling rig handy and gets your workflow moving smooth again.

- Wipe the platen roller with lint-free pads soaked in acetone every few shifts to halt abrasive dust accumulation

- Feed only standard glossy thermal media through the feed path so the adhesive backing never melts onto the heater pins

- Set the print darkness dial to minimum viable levels during long runs to keep the silicon chip below critical temp
