3. Receiving a Fax Message in Energy Saver Mode
The flow chart on the next page explains how the machine receives a fax
message while it is in a energy saver mode.
Ring Detection
While the machine is in a Energy Saver mode, the energy saver CPU moni-
tors ringing signals from the line. When the energy saver CPU has detected
two ringing signals, it activates the +5V supply to the main CPU and passes
the ring detection process to the main CPU.
After the main CPU has detected a ringing signal, the machine goes to En-
ergy Saver Mode Level 0 and receives the fax into memory. Level 0 mode
looks the same as the previous mode for users, but all the system compo-
nents are active in the background for receiving a fax message.
See point 1 on the flow chart.
Printing
If either of the following conditions is not met (condition #1 on the flow chart),
the machine will print out the fax message then return to Energy Saver Mode
in the manner described in the previous two flow charts in this section.
•
Energy Saver mode is activated during the Night Timer period
•
The machine is currently in the Night Timer period.
If both conditions are met, the machine returns to Energy Saver Mode as de-
scribed in the previous two flow charts in this section. It will print the fax
message after the Night Timer expires.
See point 2 on the flow chart.
