8. PRINTER
MAINTENANCE
8.1. Cleaning the thermal head
•
Clean the thermal head only if printing is degraded due to dirty elements on its surface.
•
Before proceeding, use a grounded wrist strap or touch a safely grounded object or a metal
part, such as a metal housing of your device to avoid damaging the printer electric
components due to static electricity.
•
Disconnect the printer power supply cable.
•
Open the cover completely to have access to the head.
•
Use a soft cloth or cotton wool dampened with isopropyl or ethyl alcohol and clean softly the
head surface.
•
Close the cover after the alcohol has been dried completely.
8.2. Cutter or paper jam removing
In case of cutter/paper jam, simply open the cover to allow an automatic cutter blade
repositioning, adjust the paper path and re-close the cover.
