MANUFACTURER. DISCARD USED BATTERIES ACCORDING TO THE
MANUFACTURER'S INSTRUCTIONS
and
ATTENTION: IL Y A DANGER D'EXPLOSION S'IL Y A REMPLACEMENT INCORRECT DE
LA BATTERIE. REMPLACER UNIQUEMENT AVEC UNE BATTERIE DU MEME TYPE OU
D'UNT TYPE RECOMMANDE PAR LE CONSTRUCTEUR. METTRE AU REBUT LES
BATTERIES USA GEES CONFORMEMENT AUX INSTRUCTIONS DU FABRICANT.

6Document skew
Max. 2.6 mm skew over a document of A4 length.
For a document longer than A4 length, occurrence of skew
exceeding 2.6 mm over any A4 length is 0.5% or less.
7Document jam detection
1) Transmission will stop and line disconnection will occur when
the end of a document is not detected within 356 mm after
scanning begins (except for the long document scanning. TF
+ 11)
2) A jam will also be declared if the document does not reach the
scanning position within 5.5 seconds (OKIFAX 5000 series)/
10 seconds (OKIOFFICE44/OKIFAX 4100) after the start of
a document feed.
Note: When a jam is detected during message transmission from
the feeder, the machine will stop scanning and disconnect
the line, but its receiving capability will remain valid.

1) From edge to edge:25% unit
2) From copy to the next copy:30% unit
The fax can detect the no-paper condition by a photosensor.
When the paper has run out in the local copy operation, the scanning
will stop with “NO PAPER ... REPLACE PAPER” on the LCD for
OKIFAX 5000 series and “PAPER OUT/JAM” on the LCD for
OKIOFFICE44/OKIFAX4100 and an ALARM LED turns on without an alarm tone.
When the paper has run out while a message is being received and
the no-paper reception is activated, the LCD display will show
“MSG. IN MEMORY”, and the ALARM LED turns on.

5 ms at 7.7 line/mm and 10 ms at 3.85 line/mm when receiving from
a non-Oki Data facsimile.
Note 2: V.34 modern performs the fall-back depending upon the
line condition automatically.
26Protocol
1) ITU-T Rec. T.30
2) Oki Data special protocol
High-speed protocol
The T.30 protocol signal from the transmitting station is sent at
message transmission speed instead of 300 bps.
Note:In high-speed protocol, 28.8 K-bps are not supported.
The heater of the fuser unit is controlled within the predetermined
temperature range by the thermistor. If the temperature of the heater
exceeds the range, the LCD displays “PRINTER ALARM 4”.
Furthermore, the built-in thermostat in the fuser unit prevents the
heater from being overheated even in the event of the failures in the
above temperature control circuit.
The following four modes are supported:
1) PC local printer function
2) PC scanner function
3) PC FaxModem function
4) Location Programing function
Note:This function will be supplied as the OKIFAX 4100/5200/
5300/5500/5600 option in case Oki Data can get the
approval in respective countries without modifying the
optional unit.
