Writing The Update Programs/Data To The Machine - Brother MFC-3340CN Service Manual

6.1.2 Writing the Update Programs/Data to the Machine

If you want to update the current programs/data stored in the flash ROM on the main PCB or after
you replace the main PCB, write the update programs/data to the flash ROM.
Writing requires a PC/AT-compatible computer running Windows 98/98SE, Windows Me,
Windows 2000 Professional, or Windows XP Home/Professional.
CAUTION: During writing, do not turn the power off, disconnect the interface cable, interrupt
writing, or write invalid data. If you do so, writing will fail, causing the PCB to be unusable. You
will need to replace the main PCB and write update programs/data to a new PCB.

procedure described below that enables your PC to identify terminals via a single virtual USB device.
NOTE: 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 BHL2-Maintenance Printer driver has been
already installed to your PC according to this procedure, skip this section.
NOTE: Before proceeding to the procedure given below, make sure that the BHL2-Maintenance
Printer driver (listed in
