1.4.16 Ready state of maintenance mode for service personnel
Drivers of the same number of virtual USB devices are required for the computer to
recognize the USB-connected terminals. If the machine is connected to the computer at each
time any repair work is performed, virtual USB devices with the same number of the repaired
machines are automatically configured on the computer. To prevent numerous virtual USB
devices from being configured, entering maintenance mode for service personnel enables
your computer to identify multiple terminals via one single virtual USB device.
Enter this mode when using the download utility or service setting tool by installing the
maintenance driver.
