2.2.4. USB Host Port

The WorkCentre 6400 contains a host connector for a USB flash drive, enabling upload of software upgrades and
download of network logs or machine settings files.
Modifying the software upgrade, network logging or saved machine settings files will make the files unusable on a
WorkCentre 6400.
The data in the network logging file is encrypted and can only be decrypted by Xerox service.
The machine settings that can be saved and restored by a service technician are limited to controller and fax
parameters that are needed for normal operation. For example, the fax address book can be saved and restored by a
service technician.
There is no method for a user, administrator or technician to move image data from the WorkCentre 6400 to a USB
device.
