6. Maintenance
Regular maintenance ensures optimal performance and extends the life of your Phomemo B246d printer.

6.2 Cleaning the Roller
If labels are not feeding smoothly, the roller might need cleaning.
- Turn off the printer and unplug the power cord.

- Use a lint-free cloth lightly dampened with isopropyl alcohol to wipe the rubber roller.
