2.2General Function Specifications
General function specifications for the product are given below. They are summaries of
whole descriptions. For convenience of description, the functions are classified in two
categories:
User functions and Service functions.
2.2.1User functions
1)Transmissions
Transmission is available by auto dial (10 one-touch numbers, 70 two-digit numbers,
as well as standard keypad dialing).
2)Reception
Reception is available by auto reception and manual reception.
3)Dual access
The machine can scan another document into document memory during memory TX/
RX and paper reception.
4)Voice request
A voice request from the transmitter is available only upon completion of the total
message transmission.
A voice request from the receiver is available at the end of each page being received.
A voice request function is available in normal transmission and normal reception.
(refer to Table 4-x)
5)Auto redial
If a call cannot be connected to the distant station because the line is busy or no
answer is returned, this feature redials the same station after a predetermined interval.
The redial interval and the number of redial tries are set by the user in the US/
CANADA version and in some INT’L versions where allowed by the PTT, and by a
service engineer in other INT’L versions.
If a communication terminates with an error in memory TX mode (no response to
POST-COMMANDS) the machine re-dials and re-transmits from the first page to the
same station.
40672201TX Rev.4
2 - 7
6)Manual redial
This feature is available to repeat dialing of the last called dial number.
There is no limit on the number of repeat attempts.
However, there are several restrictions in manual redial and feeder TX operation after
restoration of power.
After restoration of power, the machine can not return to the previous operation
condition before the power failure.
Restoration of power means that the voltage returns to the normal value after power
failure.
For example, the waiting condition of delayed preparation transmission (delayed
feeder TX) changes into abandoned documents after power failure. Abandoned
document means that the document was set on the feeder, and the phone number for
the feeder TX or TX preparation is not set.
Moreover, the waiting of redial condition of feeder TX or feeder TX preparation turns
into abandoned document conditions.
Since the registered data for redial is lost by power failure, the manual redial is not
available by the past data after power failure.
7)A.D.F.
The feeder feeds 15 sheets maximum (Letter/A4-size 13-28 1b).
When using recommended paper. 20 sheets maximum can be fed.
Note: Recommended paper: 20 1b bond paper (NA Letter and ISO A4-size)
8)Multi-Copy
The machine reproduces max. 50 copies of document with 3.85 lines/mm or 7.7 lines/
mm resolution locally.
9)Sender ID
