Automatic background sensing
A continuous document background of 0.3 OD ( optical
density ) or less will de transmitted as white.
Up to 297 mm in length.
1) Transmission will stop and line disconnection
will occur when the end of the document is not
detected within 600 mm after scanning begins.
2) A jam will also be declared if the document does
not reach the scanning position within 4 seconds
after the start of a document feed.
Note: When a jam is detected during message transmission, the
machine will stop, but its receiving capability will remain valid.

heat alarm state: Higher than 65 at the Printing
head unit base.
When an heat alarm state detected during reception,
the FAX interrupts the reception as follows:
- LCD displays “HEAT ALARM”
- Generates an alarm tone.
- Transmits a DCN signal in response to an
EOP/EOM/MPS signal from the remote station and
disconnects the line.
The heat alarm state can be automatically released
by natural cooling.
