The available memory threshold, below which ringing detection (and therefore reception into memory) is disabled

00 to FF (Hex), unit = 4 Kbytes (e.g., 06(H) = 24 Kbytes)

One page is about 24 Kbytes.

The machine refers to this setting before each fax reception. If the amount of remaining memory is below this threshold, the machine cannot receive any fax messages.

If this setting is kept at 0, the machine will detect ringing signals and go into receive mode even if there is no memory available. This will result in communication failure.

Inch-to-mm conversion during transmission

0: Disabled, 1: Enabled

0: In immediate transmission, data scanned in inch format are transmitted without conversion.

In memory transmission, data stored in the SAF memory in mm format are transmitted without conversion.

Note: When storing the scanned data into SAF memory, the fax unit always converts the data into mm format.

1: The machine converts the scanned data or stored data in the SAF memory to the format which was specified in the set-up protocol (DIS/NSF) before transmission.
