SAF memory are erased.
This bit switch is recommended for use when it is necessary
to clear the SAF, as fewer RAMs will need reprogramming.
Use this if the printer does not work, but the user wishes to
print the files. First, change the fax machine’s telephone
number (Function 51) to the number to which you wish to
forward the files, then set this bit to 1. All files in the memory
will be forwarded. This bit resets to 0 automatically.
However, you must return the fax machine’s telephone

The machine counts data errors caused by a
noisy line or defective machine.
0: If the count reaches 10 (Standard mode), 20
(Detail mode), or 40 (Fine mode), the machine
sends RTN to the other end in reply to the postmessage command. As 10 (or 20 or 40) good
lines cause the count to decrement, RTN will
only occur in bad conditions.
The number of good lines for counter decrement
and the value of error threshold can be changed
by rewriting the RAM addresses 40CB(H) and
40CC(H).
If there are more consecutive error lines in the
received page than the threshold specified by
these bits, the page is rejected. Values in
parenthesis are for Detail resolution, and those
in square brackets are for Fine resolution.
If the number of error lines divided by the total
number of lines reaches the value determined
by the settings of these bits, RTN will be sent to
the other end.

CNG (calling tone) is normally used by auto-dial fax
machines to alert a manual machine operator that
an auto-transmitting machine is on the line waiting
to transmit. This tone is not needed for manual
operation (full number dialing).
(0,1) - The machine will not transmit if the last 8
digits of the received CSI do not match the last 8
digits of the dialed telephone number. This does not
work for manual dialing.
(1,0) - The same as above, except that only the last
4 digits are compared.
(1,1) - The machine will not transmit if the other end
does not identify itself with an RTI or CSI.
(0,0) - Nothing is checked; transmission will always
go ahead.
1: Transmission will not go ahead if the ID code of
the other terminal does not match the ID code of
this terminal. This feature may not be reliable when
communicating with another maker’s product.
If this bit is 1, the speaker will operate during
memory transmission. Keep this bit at 0 if the user
complains about the noise from the speaker.

The following tables give the RAM addresses and units of calculation of the
parameters that the machine uses for ringing signal detection and automatic
dialing. The factory settings for each country are also given. Most of these
must be changed by RAM read/write (Function 95), but some can be
changed using NCU Parameter programming (Function 96); if Function 96
can be used, this will be indicated in the Remarks column. The RAM is programmed in hex code unless (BCD) is included in the Unit column.
When using RAM read/write, you must add the bank number before the fourdigit RAM address number. See section 4-1-6 for details.

Address 4144 for DTMF dialing is 3.04 s. This can be adjusted by RAM
read/write. However, if pulse dial mode is selected, a value of 20 ms from
the ROM is used, and this cannot be adjusted.
5. Pulse dial parameters (addresses 418A to 418F) are the values for 10
pps. If 20 pps is used, the machine automatically compensates.
6. The first ring may not be detected until 1 to 2.5 wavelengths after the time
specified by this parameter.
7. N must be between 0 and 15. The attenuation levels are as follows.
High frequency tone: - N dBm
Low frequency tone: - N - 2 dBm
8. 418A: Europe - Between Ds opening and Di opening, France - Between
Ds closing and Di opening
418D: Europe - Between Ds closing and Di closing, France - Between Ds
opening and Di closing
9. For address 41AD, the formula is slightly different.
Frequency = 1,000,000/(4.873 x [N+256]) Hz
10. Bits 7, 6, and 5 are for the volume during transmission
Bits 4, 3, and 2 are for the volume during reception
The three bit values range from 0 (off), 1 (minimum), to 7 (maximum)
11. Bits 7, 6, and 5 are for the volume during on-hook dial
Bits 4, 3, and 2 are for the volume during dialing

On the following pages, there are tables of factory settings for each country.
To enable the factory settings for a particular nation, program the Country
Code (RAM address 413B [use hex codes] or use Function 96 [input the decimal value]) to the appropriate setting. The country code also affects the NCU
signal status.
For each RAM address, there are two columns.
•
The left hand column shows the actual value of the parameter.
• The right hand column shows the value of the factory setting that is
stored in the RAM. The factory settings are quoted either in hexadecimal code (the actual contents of the RAM address) if there is a H after
the value in the table, or in decimal (converted from the actual hex contents of the RAM address) if there is no H after the value.
• Some RAMs must be stored using BCD; see the NCU Parameter defini-
tion table for details.
• If the table entry is blank, this means that the value is not used.

DEDICATED TRANSMISSION PARAMETERS
4.4. DEDICATED TRANSMISSION PARAMETERS
Each Quick Dial Key and Speed Dial Code has three bytes of programmable
parameters allocated to it. If transmissions to a particular machine often experience problems, store that terminal’s fax number as a Quick Dial or Speed
Dial, and adjust the parameters allocated to that number.
The programming procedure will be explained first. Then, the three bytes will
be described.
4.4.1. Programming Procedure
1. Set bit 5 of bit switch 01 to 1.

SERVICE CALLS
4.54.5. SERVICE CALLS
4.5.1.4.5.1. Excessive Jam Calls
There are two types of excessive jam call, one is the excessive scanner jam
call and the other is the excessive printer jam call. The excessive jam call
automatically notifies the service station programmed with function 99 when
the machine’s scanner or printer frequently has jam problems.
The excessive jam call algorithm uses three parameters and three counters
for the scanner and for the printer, as shown in the following table.
Parameters
DEC: Number of fed pages used to
decrease the JAM counter.
(1 - 255; 0 = Disabled)
CALL: Threshold number for
service call (3 - 15; 0 = Disabled)
CLR: Number of fed pages used to
clear the JAM counter to zero.
Counters
A: Counter used for JAM counter
decrement
JAM: Jam counter used to place a
service call
B: Counter used for clearing JAM

The excessive jam call for scanner and printer work individually, but the algorithms are the same.
Service Tables
and Procedures
The JAM counter increases when a jam occurs, and the counters A and B increases when a page is fed successfully.
When the JAM counter reaches the value stored in the CALL parameter (with
the initial setting, when it reaches 6), the machine places a service call to the
service station and sends three reports (auto service report, service monitor
report, and system parameter list). Either “document jam monitor” or “copy
jam monitor” is printed on the auto service report as an error message.
4-51
Page 79
July 16th, 1993 SERVICE TABLES AND PROCEDURES
SERVICE CALLS
However, the JAM counter will be decreased when counter A reaches the
value stored as DEC (with the initial setting, when 16 pages have been fed
successfully), and the JAM counter will be cleared when counter B reaches
the value stored as CLR (with the initial setting, when 48 pages have been
fed successfully).
So, this algorithm will alert the service station only when jams frequently occur within a short period.
These parameters can be changed by rewriting RAM data with function 95 in
the following range.
DEC: 1 through 255 (01(H) - FF(H))
CALL: 3 through 15
CLR: 1 through 65535 (0001(H) - FFFF(H))
(Usually, CLR should be three times the value of DEC.)
If either DEC or CALL is zero, the excessive jam call is disabled.
The parameters DEC, CALL and the JAM counter are listed on the system parameter list as X, Y and Z.
The Call Service indicator does not light with an excessive jam call, so that
the machine can be operated normally after the call. However, the following
RAM address should be reset to zero after the call, in order to reactivate the
excessive jam call.
4B6C
Bit 0: Scanner Excessive Jam Call 1: A call has occurred. 0: Standby (Initial setting)
Bit 1: Printer Excessive Jam Call 1: A call has occurred. 0: Standby (Initial setting)
4.5.24.5.2. Periodic Service Call
The periodic service call notifies the condition of the machine to the service
station programmed with function 99. The call is made periodically at a time
interval programmed in the following RAM addresses.
Parameters Address (H)
Call interval: 01 through 15 month(s) (BCD)
00: Periodic Service Call Disabled
Date and time of the next call
Year: last two digits of the year (BCD) 4B80
Month: 01 through 12 (BCD) 4B81
Day: 01 through 31 (BCD) 4B82
Hour: 00 through 23 (BCD) 4B83
4B7F
Caution: Data stored in these addresses have to be within the specified
range and in BCD format. Otherwise, the service call will not work
correctly.

Page 80
SERVICE TABLES AND PROCEDURES July 16th, 1993
SERVICE CALLS
When the date and time programmed at these addresses has passed, the
machine automatically places a service call to the service station and sends
three reports (auto service report, service monitor report, and system parameter list). “EM manual call” is printed on the auto service report as an error
message.
The default setting for this feature is off. To switch periodic service call on,
just program the Call Interval at address 4B7F(H). Then, the date and time of
the next call are automatically programmed. For example, if the call interval is
programmed as 03 (BCD) months and the current date and time is Dec. 24,
1993; 03:10PM, the following data are stored:
94 at 4B80(H) for 1994
03 at 4B81(H) for March
24 at 4B82(H) for 24th
15 at 4B83(H) for 3PM
To change these settings after programming, change the interval first with
function 95, exit the function, then change the remaining parameters one by
one if the settings are not the expected ones.
The Call Service indicator does not light with a periodic service call, so that
the machine can be operated normally after the call.
4.5.3.4.5.3. PM Call
If bit 7 of Bit Switch 01 is set to 0, the PM call will notify the service station
that the time for PM has come. To switch on the call, program the counter interval at the following RAM addresses in BCD format. The initial setting is
30,000 sheets.
Address Bits 7 - 4 Bits 3 - 0
410E Tens Units
410F Thousands Hundreds
4110 Hundred thousands Ten thousands
When the date and time programmed at these addresses has passed, the
machine automatically places a service call to the service station and sends
three reports (auto service report, service monitor report, and system parameter list). “PM call” is printed on the auto service report as an error message.
The Call Service indicator does not light with a PM service call, so that the
