3. Reception problem
First confirm whether the recording paper is installed properly or not before starting troubleshooting. (Refer to "Remarks".)
Note:
"596: Transmit level set" represents a service code. (Refer to 2.4.4. Service Function Table.)
Remarks:
Regarding the reception problem, we have investigated the conceivable causes in the flow chart except for the software-
related errors. However, some troubles may occur due to the software-related problems such as "OUT OF PAPER" when
the fax switches to the memory receiving mode and the memory capacity becomes full of the unprinted data. In this case,
error messages [MEMORY FULL] and its main cause, for example "CHECK PAPER" are displayed on the LCD. Once you
solve the main problem, [MEMORY FULL] will be cancelled and the reception problem will be resolved.

4. The unit can copy, but cannot transmit/receive.
5. The unit can copy, but cannot either transmit/receive long distance or international communications.
The following two causes are conceivable regarding this symptom.
Cause 1:
The other party is executing automatic dialing, the call has been received by this unit, and the CED or DIS signal response
time is too long. (In most cases, this unit detects the CNG signal and can respond to CED or DIS.) (According to the CCITT
standard, the communication procedure is cancelled when there is no response from the other party within 35 sec, so that
the other party releases the line.)

standard, the communication procedure is cancelled when there is no response from the other party within 35 sec, so that
the other party releases the line.)
(Cause and Countermeasure)
As shown in the chart above, the total handshaking time must be reduced, but because of the long distance connection and
linking of several stations, the line connection time cannot be reduced. Accordingly, the following countermeasures should be
tried.
linking of several stations, the line connection time cannot be reduced. Accordingly, the following countermeasures should be
tried.
(A)... As the 35 sec. count is started directly after dialing or directly after the START button has been pressed for models with
a START button, the other party should be called manually, if possible. Another possibility is entering two pauses at the end of
the auto dial number on the transmission side. Then the count start time can be delayed for 2 pauses (about 10 sec.).
