11.15 RECOVERY OF BD ADDRESS
From the firmware V1.2, a function to recover the BD address has been supported because the BD
address sometimes becomes indefinite. (The B-EP-GH32 does not support the recovery function.)
When the BD address is indefinite, the host cannot communicate using the registered BD address and
requires to obtain a new BD address by performing an inquiry scan. To prevent this symptom, a
function to recover the BD address has been added. Specifically, the BD address is detected at a
power on time, and if the detected address is indefinite, it is recovered to a normal value. When a
recovery of BD address is executed, “SYSTEM ERROR 19” is displayed on the LCD to notify the
completion of recovery. After this message is displayed, turning the printer off and back to on will
enable normal operations of the printer.
However, the result of this function differs depending on the Bluetooth module version.
Bluetooth module Firmware
LCD message
Version Self-restoration and BD

Version Recovery of BD
address
V244 Not supported V1.2 only Supported “SYSTEM ERROR 18”
V1.3 or later Not supported (*1) “ON LINE” (*3)
V257 Supported V1.2 or later Supported “SYSTEM ERROR 18” or
“SYSTEM ERROR 19” (*2)
*1: The firmware V1.3 or later supports the BD address recovery function, but does not support
Bluetooth module V244.
*2: Which message is displayed depends on the result of a BD address recovery.
*3: In the case of the B-EP4DL-GH30-FE-QM-R (FedEx model), “SYSTEM ERROR 18” or “SYSTEM
ERROR 19” is displayed.
Notes:
1. When “SYSTEM ERROR 18” is displayed, the printer cannot be restored by turning off and back
to on. Service call is required.
2. In the case the Bluetooth module is replaced, the printer will assign the backed up BD address to
the new module. This means the printer duplicates the former Bluetooth module.
Accordingly, the Bluetooth module shall not be replaced basically.
