5-50 3/03 WorkCentre Pro 412, FaxCentre F12 &
WorkCentre M15/M15i
5-5-1 Specifications
This section presents the electrical and environmental specifications of the FaxCentre F12.
1.
Power Ratings
Table presents the FaxCentre F12’s minimum and maximum power ratings and storage temperatures.
* VDDBIAS is connected to the system’s 5.0V supply to provide 5V tolerance on I/O signal pins (including
all inputs, outputs, and bidirectional). in systems where 3.3V signaling only is used, connect VDDBIAS to a
3.3V supply.
