The battery [A] on the MBU backs up the RA M on the MBU, which con ta ins
system parameters. It also backs up the rea l time clock in t he cpu . This bat­tery is not rechargeable. CN1-7 te lls the cpu whe th er the ba ck-up powe r
(CN1-9) comes from the battery or fro m t he +5 V power supply.

A rechargeable battery [B ] on the FCU board backs up the SAF memo ry and
the real time clock for 1 hour. While the main power is on, the +24V supply re­charges the battery. There is no battery switch.

If there is data in the SAF memory, the rechargeable batt ery [B ] also backs
up the real time clock, to preserve the MBU battery.

Resolution

This machine scans in dots per inch , to meet Group 4 stand ards. The various
scan resolutions are ach ieved as follows.

Standard - Immediate transmission: The tx motor feeds the documen t a t 200
lines per inch. The video processor executes OR processing t o co nve rt t he
data into 100 lines per inch .
Memory transmission: The motor feeds the docu men t at 10 0 lines per in ch,
and no OR processing is needed.
Detail - The tx motor fee ds th e do cument at 200 lines pe r in ch. There is no
OR processing, and the da ta is transmitted at 200 lines pe r inch.
Fine - The tx motor feeds the documen t and tra nsmits data at 400 lines per
inch. If the other t ermin al cannot receive at this resolut ion , alternate lines of
data are deleted, so the effective resolution of the transmitted da ta is 200
lines per inch.

Page Separation and Data Reducti on

Incoming pages that are similar in lengt h to the copy pa per ma y be red uce d
in the sub-scan direction to fit on the paper. Whether or not this happens de­pends on the settings of bits 1 and 2 of bit switch 02 .

Reduction Enabled
If bit 2 of bit switch 02 is at 0, the data will be reduced in the page memory to

fit on the copy paper. However, data will only be redu ced if the leng th of th e
incoming page is between 5 mm shorter and a certain maximum length. This
maximum incoming page lengt h that can be reduced depen ds on the co py pa­per size and on the reduction ratio sto red in RAM addresses 00014F and

000150.
Each paper size can be progra mmed wit h a sep arate reduction ratio. In ea ch

of the two RAM addresses, th ere is one bit for each p ossible paper size. The
combination of the bit sett ing s det ermines the ratio for that paper size.

Bit 7: Not used Bit 5: Legal Bit 3: A4 Bit 1: B5

Ratio = 4/3 Ratio = 8/7 Ratio = 12/11

The values are calculate d as follows.
Maximum incoming page lengt h that can be reduced =

(Copy Paper Length - 5) x Reduction Ratio

For example, for A 5 wit h a reduction ratio o f 4/3

Max incoming data length = (148 - 5) x 4/3 = 1 90.7

Incoming pages that are longer than the maximum le ngth will not be reduced ,
but will be printed on two pages and treated in accord an ce with the sett ing of
bit 1 of bit switch 02. If this bit is 1, the bottom few lines of the page will be re­peated at the top of the next page. If this bit is 0, the next page will continue
from where the first page left off.

Reduction Disabled
If bit 2 of bit switch 02 is at 1, the data will not be reduced . Howe ver, if the in-

coming page is up to x mm longer than the copy pa pe r, the excess portion
will not be printed. The value of x can be from 0 to 15 mm. It is determined by
the setting of RAM address 00015 1 (cop y mode : bit s 3 to 0, receive mode :
bits 7 to 4; bits 3 and 7 are the most signif icant bits).

Standby mode

• If the fusing lamp is belo w 8 0 °C, th e I/ O Po rt makes CN1-8 go high.

This switches on the fusing lamp.

• If the fusing lamp goes above 80 °C, CN1-8 goes lo w, which switches

off the fu sing lamp.

Printing

• When a ringing signal is detect ed, CN1-8 goes high, to switch on the

fusing lamp. Also, t he o zone fan switches on.

• During printing, the temperature is kept at 170 °C. If the temperature

rises above 170 °C, the output from the comp arator changes state. This
causes CN1-8 to go low, which switches off the fusing lamp.

• If the comparator fails, there are additional safety cutoffs at 280 °C (th er-

mistor) and at 400 °C (thermostat).

After printing

• When the fusing lamp temp erature falls back below 150 °C, th e ozo ne

fan switches off.

Service Note

When an error occurs, the I/O Port switches off the fusing lamp by raising
CN1-7 to high. The print er will b e d isab led , a nd an Auto Service Call will be

When this bit is set to 1, all items stored in the RAM are
reset except the clock, and then this bit changes back to 0
automatically. Also, all image files in the SAF memory are
erased.

When this bit is set to 1, some items stored in the RAM are
reset, then this bit changes back to 0. All items are reset
except the bit switch and NCU parameter settings, clock,
own tel. no., CSI, RTI, TTI, Quick Dials, Speed Dials,
Groups, and the TCR memory. Also, all image files in the
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.

1: Instead of the personal code, the following data are listed
on the TCR.
First number: Final modem rate (for example, 14.4K means
14,400 bps)
Second and third numbers (Rx mode only): These are a
measure of the errorrate. The left hand figure is the low byte
and the right hand figure is the high byte. In general, a
larger number means more errors. These numbers are fixed
at 0 for tx mode.
Fourth number: Cable equalizer; 00 = Equalizer is Off, 01 =
Low, 10 = Medium, 11 = High

Used for testing. Set this bit to 1 to hear the fax data signal
(phase C of CCITT T.30 protocol).
Make sure that you reset this bit after testing.

This is a fault-finding aid. The LCD shows the key
parameters (see the next page). This is normally disabled
because it cancels the CSI display for the user.

(0,1), (1,0): Normally, RDS systems are locked
out, but the user can temporarily switch RDS
on to allow an RDS operation to take place.
RDS will automatically switch off again after a
certain time, which is stored in a RAM address
(see section 4-5). Note that, if an RDS
operation takes place, RDS will not switch off
until this time limit has expired.

If communication did not reach phase 3 of
CCITT T.30 protocol (such as for a telephone
call), this communication can be listed on the
TCR if this bit is at 1.

If this bit is 1, error codes are printed on the error
reports for the user.

If this bit is 1, a mark will be printed on the left
edge of the page at any place where a line error
occured in the data. Such errors are caused by a
noisy line, for example.

If this bit is 1, the TTI stored in the machine is
printed at the top of the copy.

In addition to the TTI, the other end’s RTI or CSI
will be printed on top of the pages that the
machine receives.

When the sending terminal is controlled by a
computer, there may be a delay in receiving
page data after the local machine accepts set-up
data and sends CFR. If this occurs, set this bit to

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.

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.

Program this bit switch if the machine is
behind a PABX. The access number is
the number the user must dial to get an
outside line. If the machine detects the
access number at the start of a
telephone number, it will connect with
the PABX, pause for a few seconds,
then dial the number.
Example: If the access number for the
PABX is 9, the bit switch must be F9. To
do this, set all bits to 1 except bits 1 and

2.
If there is no PABX, set all bits to 1.

voltage during a back to back test.

If this bit is 0, the Short Preamble feature is
switched on.

If this bit is 0, the AI Short Protocol feature is
switched on.

If the setting is 1, the machine will hang up if
it receives the same signal twice. If the
setting is 0, the machine will ignore echoes
from the line.

The machine will send DCS (G3 set-up
signal) if it receives DIS. If echoes are
frequent, setting this bit to 1 will allow the
machine to wait for the second DIS before
sending DCS.

If this bit is 0, ECM is switched on.

0: Data cannot be stored in the SAF during
reception if the memory is full, so, if this bit is
set to 0, the machine will wait until the page
has been fed out. However, communication
will take longer to complete.
1: The post message response is sent
earlier, but the paper has not been fed out
yet, so if there is a jam after this, data may
be lost.
This bit is ignored during memory reception.

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.

Notes

1. If a setting is not required , store FF in the address.

2. Tone frequencies are stored in BCD in the follo wing fo rmat .
Examples:
a) 380 Hz HIGH 0 3 LOW 8 0
b) 1210 Hz HIGH 1 2 LOW 1 0

3. Italy and Belgium only
RAM address 3B5: the lower four bits have the following meanin g.

Bit 3 1: Country dial tone cadence detectio n enab led
Bit 2 1: International dial tone cadence detectio n en ab led
Bit 1 1: PABX dial tone cadence detection enabled
Bit 0 1: PSTN dial tone cadence detection enabled

If bit 3 is 1, the functions of the following RAM ad dre sses are chan ge d.
3A9: tolerance for on or off state duration (%), coded as in address 399.
3AC: on time, hex code (unit = 10 ms)
3AD: off time, hex code (unit = 10 ms)

If bits 2, 1, or 0 are 1, the functions of the followin g ad dre sses are
changed in a similar way to that described for bit 3 = 1.
Bit 2 = 1: 39E, 3A1, 3A2; Bit 1 = 1: 384, 387, 388;
Bit 0 = 1: 374, 377, 378

4. Belgium only:
Address 375/376 for DTMF dialling is 3 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 (add resse s 3C4 to 3C9) are the value s fo r 10 pps.
If 20 pps is used, the machine au to matically compensates.

6. The first ring may not be detected until 1 to 2.5 waveleng ths after the time
specified by this parameter.

7. The level must be betwee n 0 a nd 15 . Th e a ttenuation levels are a s fo l­lows.
High frequency tone: - N dBm
Low frequency tone: - N - 3 dBm
RAM address 3CC is stored in units of -dBm x 0.5, but if this paramete r is
stored using Function 09 as parame ter 19, the value is in units of -dBm.

On the following pages, there are tables of factory settings for each cou nt ry.
To enable the factory settings for a particular natio n, prog ram the Cou ntry
Code (RAM address 000369 [use hex codes] or use Function 09 [inp ut the
decimal value]) to the appropriate setting. The country code a lso a ffects the
NCU signal status (see section 2-3-7 ).

• 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 set tin g that is stored in the RAM. The factory settings
are quoted either in hexadecimal cod e (th e act ual co nten ts of the RA M 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 th e NCU P ara meter definition

table for details.

• If the table entry is bla nk, this means that the value is not use d.

• The settings for Asia are also used for Hong Kong, South Africa, New Zea -

land, Singapore, an d Malaysia.

4.4. DEDICATED TRANSMISSION PARAMETERS

Each Quick Dial Key and Speed Dial Code has seven bytes of programmable
parameters allocated to it. If tra nsmissions to a particular machine of te n exp e­rience problems, store that termina l’s fax number as a Quick Dial or Speed
Dial, and adjust the parameters allocated to that number.

The programming procedure will be explain ed first. Then , t he seve n bytes will
be described.

If training with a particular remote terminal
always takes too long, the initial modem rate
may be too high. Reduce the initial Tx modem
rate using these bits.

0: Training is shorter so communication costs
are reduced. However, the communication is
not so reliable.
1: The longer training time ensures a higher
reliability for the communication.

These bits determine the capabilities that are
informed to the other terminal during
transmission.

0: The parameters in these seven bytes will be
ignored. The current settings of the relevant bit
switches, NCU parameters, and RAM
addresses will be used.
1: The parameters in these seven bytes will be
used when transmitting to the fax number
stored in the Quick Dial Key or Speed Dial
Code that these bytes are allocated to.

Set this bit to 1 if echoes on the line are
interfering with the set-up protocol at the start of
transmission. The machine will then wait for the
second DIS or NSF before sending DCS or
NSS.

For example, if ECM is switched on but is not
wanted when sending to a particular terminal,
set this bit to 1.

If this bit is 0, Short Preamble is always used
when transmitting to this terminal.

If this bit is 0, AI Short Protocol is always used
when transmitting to this terminal.

If this bit is at 1, secure transmission will always
be used when communicating with the number
stored in this Quick/Speed Dial.

Use a higher setting if there is signal loss at
higher frequencies because of the length of wire
between the modem and the telephone
exchange when calling the number stored in
this Quick/Speed Dial.

Also, try using the cable equalizer if one or
more of the following symptoms occurs.

•Communication error with error codes such as
0-20, 0-23, etc.

•Modem rate fallback occurs frequently.

Byte 3

FUNCTION AND COMMENTS

Tx level
If communication with a particular remote terminal often contains errors, the signal
level may be inappropriate. Adjust the Tx level for communications with that terminal
until the results are better.

The Tx level is the value stored in this byte (in hex code) multiplied by -1.

Byte 4

FUNCTION AND COMMENTS

CCITT T1 timer
If you wish to use a different T1 timer than the NCU parameter setting when sending
to a particular terminal, adjust this byte. The T1 timer is the value stored in this byte
(in hex code), multiplied by 1 second.

Caution: Note that if the value of this byte is 0, the T1 timer will be 35 s.

Caution: If the value of byte 4 is 0, the CCITT T1 timer is 35 s.

Therefore, every time you program a set of dedicated
transmission parameters, be sure to input the correct T1 timer
into byte 4.

Bytes 5 to 7 are only used if the ISDN kit has been installed. These bytes are
explained in the service manu al fo r t he ISDN kit.

If the Call Service indicator is lit, one of the following conditions has occurred.

• Mirror Motor Locked (hexag on al mirror mot or lock fa ilure)

• Hot Roller Down (fusing lamp failure )

• LD Power Control Failure (laser diode power con tro l failure)

• Main Motor Locked (main motor lock fa ilure)

• Charger Leak (transfer coro na charg e lea k)

To find out which problem has occurred, either:

• See the Auto Service Call report th at was se nt to the se rvice station for

the problem with the machine. This report lists a sub -cod e, as well as
the error messgae; this sub-code may help you find the prob lem.

• Check the error code history.

• Try to clear the service call condition: switch the power off, wait 10 sec-

onds, then switch back on.

If the problem remains, work through the appropriate tro ubleshooting proce­dure from the following pages.

After each troublesh oo tin g attempt, reset the machine and try to operate it. If
the machine still does not work, cont inu e troubleshooting.

Symptom: Charger Leak (Error Code 9-17)

This error occurs if FCU CN23-3 stays high for 3 s or more while the transfer corona is on
(sub-code 31)

Check Action if Yes Action if No

Clean the transfer corona wire and unit.

Check that the FCU outputs the power and trigger signals to the power pack. If not, re­place the FCU.
Replace the FCU, power pack or transfer corona unit if the problem still occurs.

Symptom: LD Power Control Failure (Error Code 9-20)

This error occurs in either of the following conditions:

• Error in the Laser Interface (LIF) chip on the FCU (sub-code 41 or 42)

• Laser power failure (sub-code 43)

Check Action if Yes Action if No

1. Do the front cover inter­lock switch and front
cover microswitch both
pass +5V?
