The following problem will occur with the 22 pin-connector which has been used between the
FCU and NCU in some models.
FAX T.S. Section, T.S. Department
Assistant General Manager
H. Motojima
[Cause]
To pr e ve nt the pin fr om bend ing and to improve reliability, the vender has mod ifie d the style of
the connector (both holder and header) without a part number change.
Ho wever, th ere is no interchangeabilit y between the n ew one and the old one.
[Symptom]
If the old holder is connected with the new header on the FCU and NCU, the contact between
them will be incomplete.
Interchangeability of each type is shown below. (See figure A)

[ Solution]
If the holder is an old one and the header is a new one, the edge of the holder must be cut off
when the NCU and/or FCU are replaced in the field. (See figure B)

[Countermeasure in the field]
The countermeasu re method depends on the CV (Cop y Volu me) of the machine.

• If the CV is more than 400 sheet s/mo nth
Change the Eraser to the modified one and turn VRC on the power pack to the maximum.
Note:The increase in the powe r of VRC may de crease the life time of the master unit, so for
customers whose ACV/month is more than 400 sheets, the Erase r shou ld be chan ge d.

SYMPTOM
When updating the ROM in the machine using EPROMs, NG is displayed on the LCD. The
updating is unsuccessful.
CAUSE
When options (PCFE, HD, ISDN etc.) are installed in the ma chine, the system data bus is
crowded. If EPROMs with an access time of 120ns are used for updating the ROM inside
the machine, the CPU read setup time is too short, so the program updating is
unsuccessful.
SOLUTION
Use EPROMs with an access time of 100ns or less for all fax machines.
For example:
M27C4001-10F1: OK
27C040-10: OK
M27C4001-12F1: NG
D27C4001D-12: NG
We recommend using P/N 1905-0020 (M27C4001-10F1) for the blank EPROM.

The year 2000 issue was explained in RTB No. General-011B.
That RTB explains only the technical matters of what will happen after the year 2000 in
some models, and the countermeasures.
At this time, we would explain how to talk with customers about the year 2000 issues
related to fax machines.
Basically, we can say to the customers that there is no major issue reated to basic
operation after the year 2000, and they don't need to take any preventative action before
the year 2000.
The only thing that the customers need to know is that the following operations will be
changed after the year 2000.

B) Adjustment of the weekly timer (Heater timer)
This is only for customers who use the weekly timer. (We do not think that many
customers are using this function.)
Please recommend adjusting the timer on Sunday if the customer can do it.
If they cannot do it on Sunday, the ROM should be changed to the new one.
The new ROM includes the countermeasure for the above A) also.

SYMPTOM
This RTB is to clarify the symptom for the following error code.
Error code 0-52: Polarity change detected during communication.
CAUSE
Polarity change is detected during communication and the machine disconnects the line in
the following conditions (error code 0-52).
1. When the machine is at the Rx side (receiving a message) and when G3 bit switch 0B
bit 1 (Protocol requirements: Spain) is set to 1 (Enabled).
The machine immediately disconnects the line when it detects polarity change after
receiving DIS/NSF.
2. When the machine is at the Tx side (transmitting a message) and when G3 bit switch
03 bit 7 is set to 1.
The machine immediately disconnects the line if it detects polarity change twice after
receiving DIS/NSF.
NOTE:
G3 Switch 03
No FUNCTION COMMENTS
RC RE ASIA
The following explanation must be added to the service manual.

1:
7 Polarity detection during
communication
0: Disabled 1: Enabled
The machine disconnects the line when it
detects polarity change twice after
receiving DIS/NSF.
This detection is enabled only when the
machine is in Tx mode.

3) Send later mode with memory and without memory
The calling must be made at the set time after the year 2000.
4) Automatic re-transmission.
When a communication error occurs, the machine calls the same dest ination again
automatically after an interval. This will function correctly afte r the yea r 2 000.
5) Weekly timer and night timer
The energy saver mode (fusing unit) control will work correctly.
6) Displayed date after a power failure
The correct date will be kept by the battery.
7) Leap year
Machines must recognize the year 2000 as a leap year and the above 1) – 6) will
function.
8) The year 2001
The above 1) – 6) will function in the year 2001.

a) The day of the week that appears on the display only in the clock adjustment
mode is returned back to SUNDAY every time the clock adjustment is done
after the year 2000.
So, the programmed weekly timer does not work correctly. (AFO does not
have the weekly timer.)
If the clock adjustment is not done after the year 2000, the date and the day of
week is kept correctly.
b) Clock adjustment is available only for the year 91 through 99. The other years
cannot be set. (Month, day and time can be adjusted.)

2) K200 (FAX7000L)
a) Clock adjustment is available only for the years 88 through 99. The other years
cannot be set. (Month, day and time can be adjusted.)
b) The send later mode does not function (no calling happens) if time passes into
the year 2000.
No report is printed and the rest of the message in the memory is not cleared
automatically, but it is cleared by user operation.
c) Automatic re-transmission is not done if the year 2000 starts in the interval after
the transmission failure.
The rest of the message in the memory is not cleared automatically but it is
cleared by user operation.
d) The displayed date is reset and turned back to ‘88 in the event of a power
failure after the year 2000.
e) The day of the week will be wrong if the clock or date information is
adjusted after the year 2000.

SYMPTOM
It is impossible to use the utility program HEXDIV.EXE for the Schmidt1 and F66 in the
normal way. However, using this program, the firmware file can be divided into 2 or 4 files
so that it can be written to the EPROM.
SOLUTION
If some options are added to the command line, the firmware files for the Schmidt1 and
F66 can be divided.
Options
– b start address
– e end address
– M offset
– s : The source file is in the Motorola S format
– S: The output file is in the Motorola S format
– O file name: The output file name
Foe example, the file for the Schmidt1 can be divided into 2 files as follows.
C:\> hexdiv-bf00000 -ef7ffff -Mf00000 -s -S -O H5457200.LOW H5457200.MS
C:\> hexdiv-bf80000 -effffff -Mf80000 -s -S -O H5457200.HIG H5457200.MS
H5457200.LOW (or HIG) is the output file name, H5457200.MS is the source file name.
