3.1 Resetting Irregular Power Supply Detection Counter
The irregular power supply detection counter increases by one when the machine detects
irregular power supply. When the counter reaches the limit and the irregular power supply
detection error is displayed, replace the low-voltage power supply PCB ASSY, which may
have been damaged by repeated irregular power supply, and reset the irregular power
supply detection counter. In this case, if the same power supply is used, the same error may
occur even when the low-voltage power supply PCB ASSY is replaced. Ask the user to
review the installation environment.

Maintenance USB Printer".
(4) Drag and drop the "SQWAVE.PJL" file onto the "Brother Maintenance USB Printer" icon.
(5) Turn OFF the power switch of the machine.
