The WorkCentre 3550 contains a host connector for a USB flash drive, enabling printing from USB, scanning to USB
and upload of software upgrade files.
Autorun is disabled on this port. No executable files will be accepted by the port.
Modifying the software upgrade or saved machine settings files will make the files unusable on a WorkCentre 3550.
The machine settings that can be saved and restored by a service technician are limited to controller parameters that
