Cautions

• Never turn off the main power switch when the power LED is lit or flashing. To avoid damaging the
hard disk or memory, press the operation power switch to switch the power off, wait for the power
LED to go off, and then switch the main power switch off.

• The main power LED () lights or flashes while the platen cover or ARDF is open, while the main
machine is communicating with a facsimile or the network server, or while the machine is accessing
4
the hard disk or memory for reading or writing data.

• EQM and rx level are fixed at "FFFF" in tx mode.

• The seventh and eighth numbers are fixed at "00" for transmission records and ECM
reception records.

Rx level calculation
Example:

4
The four-digit hexadecimal value (N) after "L" indicates the rx level.
The high byte is given first, followed by the low byte. Divide the decimal value of N by -16 to
get the rx level.

In the above example, the decimal value of N (= 0100 [H]) is 256.

So, the actual rx level is 256/-16 = -16 dB

setting, mail cannot negotiate between terminals; the mm/inch selection is determined by the

0: Returns the report after each transfer.
1: Returns the report only if an error occurred during transfer.

Destination Error Handling for Reception Transfer Request

This setting restricts transfer transmission based on whether the final destinations are correct or
not.
0: The transfer station transmits to correct destinations only (addresses with no errors in them).
2 1: If any address has an error in it, the transfer station transfers no transmissions and returns a
transfer transmission failure report to the requestor that initiated the transfer.
There is no negotiation between the transfer initiator and the transfer station to determine whether
the final destination addresses are correct or not. This setting determines whether or not the
transfer station transfers the transmissions if there is a mistake in even one of the final destination
addresses.

Polling ID Check for Reception of Transfer Request
