About RFID Module Auto Detection
The printer has a built in function to enable the RFID mode automatically when the printer is power on
after you have installed the RFID kit. Or, disable the RFID mode automatically when the printer is power
on after removing the RFID kit.
CAUTION
Be sure to power off the printer and disconnect the power cord, before installing or removing the RFID kit.
After installing the RFID kit
When the printer is power on, the printer shall enable the RFID function so that RFID will be shown in the
Interface menu of the Settings mode.
When the buzzer sounds six times during power on (from power on until the Online screen is shown), it
means the printer detected the RFID module, but the communication between them fails. In this case,
check the wiring.
In this condition, if the printer received commands related to RFID write/read or <IP5>, the printer cannot
operate and keeps showing RFID System Error until the printer is power off.
After removing the RFID kit
When the printer is power on, the printer shall disable the RFID function so that RFID will not show in the
Interface menu of the Settings mode.
If the printer receives commands related to RFID write/read or <IP5>, command error or NAK response
will occur.
