7.1.2 Installing the Maintenance USB Printer Driver

If you want to change the programs stored in the flash ROM on the main PCB or after you
replace the main PCB, load the desired programs to the flash ROM.
Loading requires a PC/AT-compatible computer running Windows 98SE/Me, Windows 2000
Professional, Windows XP Home/Professional, or Windows Vista.
Caution: During loading, never turn off your PC or the machine, unplug the USB interface
cable, interrupt loading, or load invalid data. If you do so, loading will fail, causing the PCB to
be unusable. You will have to replace the main PCB and load programs to a new PCB.
Preparation
You need the Brother Maintenance USB Printer driver and filedg32.exe (provided by Brother
Industries). Save them in an arbitrary folder in your PC.

Installing the Brother Maintenance USB Printer driver

To identify machines connected via USB direct interface, the PC requires the corresponding
driver for the virtual USB device. If you connect any number of machines to your PC, the same
number of virtual USB devices will be automatically configured on your PC. To prevent many
virtual USB devices from being configured, use the unique driver installation procedure
described below that enables your PC to identify terminals via one single virtual USB device.
NOTES: • Once this installation procedure is carried out for a PC, no more driver/software
installation will be required for that PC to identify machines. If the Brother
Maintenance USB Printer driver has been already installed to your PC according to
this procedure, skip this section.
