What to do if Monarch 9855 Printer displays “743 Program tag failed”?
- BBrandy VillaSep 2, 2025
If the Monarch printer displays a “743 Program tag failed” error, it means the RFID tag was detected but couldn't be programmed. Try increasing the number of write attempts. If the error persists, adjust the attenuation setting by one increment, either increasing or decreasing it. Be aware that setting the attenuation too low might affect the data programmed in adjacent labels.
