2. IC protectors replacement
ICPs (IC Protectors) are installed to protect the TX motor drive circuit
and verification stamp drive circuit. ICPs protect various ICs and elec-
tronic circuits from an overcurrent condition.
The location of ICPs are shown below:
(1) F100 (ICPS10) is installed in order to protect IC’s from and
overcurrent generated in the verification stamp drive circuit. If F100
is open, replace it with a new one.
(2) F101 (ICPS18) isinstalledin ordertoprotect IC’sfrom anovercurrent
generated in the TX motor drive circuit. If F101 is open, replace it
with a new one.
In addition to the replacement of F101 and F100, the factor causing
F101 and F100 to open must also be repaired. If not, F101 and
F100 will open again.

1) Soft switch mode
In this mode, the soft switch are set and the soft switch list is printed.
•OFF to ON of telephone billing function which is using the image
memory is used (Note: In the existing set, the telephone billing
code function is specified from OFF to ON when the timer system
communication (including the batch communication) is set.)
Here,thememoryisusablewhenthetelephonebillingcodefunc-
tion is on. It can be set from ON to OFF while the memory is
used. However, if setting is practically changed even once, it can
not be returned from OFF to ON.
•Switching ON/OFF of PC interface function during the use of im-
age memory.
•OFF to ON of department control function during use of image
memory.
(Note: In the existing set, the department control function is set
from OFF to ON when the timer communication (including the
batch sending) or the memory hold is set.)
•ON to OFF of continuous serial polling function when the con-
tinuous serial polling is started.
(Note: In the existing set, "ON to OFF of the continuous serial
polling function when the continuous serial polling is registered"
has been applied, but the conditions are now moderated. How-
ever, registration is impossibletotheprogram of the new continu-
ous serial polling when the continuous serial polling function is
OFF.)
•In addition, change of all soft switches during communication
7 Linked change of data (This is the same even in the optional setting.)
•When the department control function is off, the multi TTI func-
tion and telephone billing code function are turned off.
2) Print area
According to the size of the specified sheet, the effective printing area is
printed.
3) ROM & RAM check
The sum value of ROM, the work and the back-up RAM are checked.
The RS232C interface is also checked. If any error occurs, the buzzer
willinform it. (Refertothe following table). Finally,theresult will be printed.
This diagnosis does not check the flash memory. The flash memory is
checked with the flash memory test.
For the short and long sounds, one pattern is as follows.
Main system: 0.5 seconds ON/0.5 seconds OFF
Sub system: 1.00 second ON/0.5 seconds OFF
The execution state of checking is as follows. Moreover, the list of the
check result is output after checking is ended.
1 Switch number selection
•Press START key for setting of the next soft switch. If the soft
switch number is the final, pressing START key will exit the soft
switch mode.
•Enter two digits of a soft switch number to set the switch number.
If a switch number of unexisting soft switch is entered, key error
buzzer sounds to reject the input.
2 Data number selection
The cursor position shows the data to be set.
Pressing#keymovesthecursortotheright.If,however, the cursor is
on data number 8, pressing # key shifts the cursor to data number 1
of the next switch number. If the switch number is the final, pressing
# key will exit the soft switch mode.
Pressing key moves the cursor to the left. If, however, the cursor is
on data number 1, pressing key shifts the cursor to data number 1
of the former switch number. If the switch number is 1, pressing
key will not move the cursor and the error buzzer will sound.
3 Data setting method
Press the FUNCTION key, and the data at the position of the cursor
will be reversed to 0 when it is 1, or to 1 when it is 0. (If the soft switch
can be changed at the bit (Refer to 6 .), the error buzzer will sound
with the process not received.)
4 Outputting method of soft switch list
In the soft switch mode, press the REPORT key, and the soft switch
list will be output.

•It is shifted to set the next soft switch by pressing the START
switch.
•It is shifted to set the next soft switch with the [#] key.
•It is shifted to set the last soft switch with the [ ] key.
•It is shifted to set another soft switch by inputting two digits as the
switch number. (When 2 digits are completely input.)
•Output of the soft switch list is started.
6 Inhibition of data change
(This is also applicable for the optional setting.)
In the following case, it is inhibited to change the data with the key
error buzzer.
•Switching ON/OFF of ECM during the use of image memory.
•Switching OFF to ON of the print hold function when the print
hold pass code has not yet been registered.

10) Comm. check mode
1
Turn on the line monitor.
2 Turn off the COVER SHEET FUNCTION.
3 Set line equivalence at 0 km.
After the check, it is necessary to be sure to return the aforementioned
soft switches into the initial state.
(Clear the memory with the diagnosis.)
11) Memory clear
Clear the back-up memory to initialize the soft switches.
The flash memory will be initialized. Then, the initialized list be output.
12) Flash memory
The flash memory is checked.
The ordinary memories (ROM, SRAM, DRAM) are checked in the ROM
& RAM check process. The write/read test is taken every block to print
the result.
When an error occurs, the following error buzzer will sound.
During operation of this diagnosis, dual operation is not possible at all.
If this is excessively repeated, it will shorten the life of the flash memory.
13) All FAX/TEL. entry mode
The function is used to simplify the registration of FAX/TEL No. during
aging.
1 The diagnosis mode is activated. If anything is not registered in the
Rapid number 01 or any program or group is not registered, it will
pass the diagnosis without doing anything.
2 The FAX/TEL number (including the substitutive destination) of the
Rapid number 01 is copied to the Rapid numbers 02 thru 48.
3 FAX numberofthe Rapid number01is copied toSPEEDkey numbers
001 thru 200.
4 If any chain dial is not in the Rapid number, the Rapid numbers 02
thru 48 and SPEED key numbers 001 thru 200 are registered in the
group number 01.
If any chain dial is set, the group will be not produced but the chain
dial setting alone of the Rapid number 01 will be reset.
(In all others except the Rapid number 01, the chain dials will be
continuously set as they are.)
(16th and subsequential letters of the destination name registered in the
Rapid number 01 will be discarded.)
14) Dept. passcode
The department passcode list is printed.
15) Conf. passcode
The confidential passcode list is printed.
Differing from printing of one box alone soon after registration, the con-
fidential passcodes of all boxes are printed.
16) Print hold code
The print lockout passcode No. is printed.
17) Memory set mode
The set and dump list of the memory content is output.
•The address (8 digits (P) generally including the bank information is
input, and the data of 2 digits is continuously input.
Inputting is done in the hexadecimal mode. The ten-key is used for 0
thru 9, and the alphabetic keys A (RAPID 01 thru 06) are used for A
thru F.
•During data inputting, the address can be moved forward and back-
ward one byte by one byte with " " and "#". (The address prior to the
address 0 is looped as the maximum address.)
•The Validity of the address is not checked. Accordingly, writing/ read-
ing operations are possible in the address of the memory not as-
signed, the address of ROM and so on.
(However, as practical, writing is not done, and the data content runs
short each reading.)
Though writing is possible in the flash memory, a little time is re-
quired.
It is also necessary to take care that the life of the flash memory is
excessively shortened if much data is written in the flash memory.
Since it may run away depending the written content, take minute
care for the writing address.
•When the REPORT key is input, the memory dump list is produced
from the displayed address (here, it is limited at the 16-byte bound-
ary address (address with end 0) which does not exceed the speci-
fied address and is just in front.). The dump list is output to a maxi-
mum of 99 pages. If any data of one page can be repeatedly devel-
oped and printed, the list is sufficient. But it is not desired that the
content of plural pages are developed in the memory once and are
then printed. If the STOP key is pressed, it will pass to the diagnosis
after the page which is now being printed is completed printed.
If the address exceeds the maximum address, it will return to the
address 0 and printing will be continued.

19) Dial test mode
The mode is used to inspect whether dialing is accurate in two kinds of
dial modes . All data which can be dialed in this mode are automatically
called up in both PB mode and DP mode.
When this mode is activated, the following operations will be automat-
ically executed . Whether the dialed content is right or not is judged with
the external instrument which is connected to the line cable.
1 After shift to the FAX diagnosis mode, press RAPID 24.
(Also switch the display with the [ ] and [#] keys.)
2 Press the START key.
3 Turn on CML, and dial the following in the PB mode.
1, 2, 3, 4, 5, 6, 7, 8, 9, , 0, #
4 Turn off CML 500 mS alone.
5 Dial the following in the DP mode.
1, 5, 9, 0
6 After dialing, turn off CML.
This mode uses the ordinary auto dial. (Accordingly, the signal sending
time and minimum pause are all the same as ordinary.
The measurement result in this mode is completely all the same as in
the ordinary dial mode.
Moreover, the same process as above is also done in the dial test mode
which is executed in the product check mode.
20) Copy diag mode
In order to shorten the process time during production, this mode is
usedtoautomatically switch the copy mode. Three menus are provided.
1. 1 Set up two documents. (In case of two documents or more,
there is no problem.
2 Press the START key.
3 Copy1st document in the finemode/densityAUTO.(One sheet
is printed in the ordinary copy mode.)
4 Copy 2nd (subsequential) document in the intermediate tone
mode/densityDARK.(In the ordinary copying mode, one sheet
isprintedwhentheRESOLUTION key is pressed three times.)
When copy test is tried during production or is checked in two modes
(fine and intermediate tones), this mode is provided to reduce the trou-
blesomework which makestheoperator stand asidetochange the mode.
Accordingly, the fine and intermediate tones are merely switched, and
the mode is not switched to another mode. (Input of the image quality/
density key is invalid.)
2. Try the copy in the mode fixed at COPY REDUCE 95% and fine
mode/density AUTO. At this time, don’t change the soft key of
COPYREDUCE. (Input oftheimage quality/density key isinvalid.)
3. Continuously try the above items 1 and 2.
21) Signal Send Mode2
The signals concerned with V.34 & V.8 are checked.
After this mode is activated, press the START key, and the signals will
be sent in the following sequence.

Rapid key 08: Life all clear
The mode is used to clear the life counter of the printer of the counter
of the auto feeder.
Note: The counter shows the operational state of the printer (e.g. how
many sheets have been printed since start of use?). The ordi-
nary memory does not reset the counter. Accordingly, it is nec-
essary to reset this counter in addition to the ordinary memory
clear if the content in the memory on the control PWB is broken
because of PWB repair, etc. (In the production stage, it is nec-
essary to execute this in the last process.)
Rapid key 09: Life entry mode
(For Serviceman temporary counter)
The mode is used to set a desired value for the judgment value (alarm
judgment counter value) of the general purpose life counters 1 thru 3 of
the printer. If the life of a consumable part (developer, imprinter, etc) is
set, the model which has the error display and RMS function will inform
RMS when the counter reaches the set value. For setting, proceed with
the following procedure.
1 When the life counter setting mode is selected, the following will be
displayed.
The cursor blinks at the top data.
Three counters can be selected with the "#" and " " keys.
2 Inthe state 1 , input a desired setting number of 6digitswith the ten-
key.
3 After input of 6 digits, shift to another counter with the "#" and " "
keys as necessary. When all necessary counters are completely in-
put, press the START key.
4 "STORED" will be displayed with the set values stored into the
memory. For checking, retry this mode.
Note: Thecounter shows the operationalstateofthe printer (how many
sheets have been printed since start of use? and others). The
ordinary memory does not reset the counter. Accordingly, it is
necessary to reset the counter or do the clear process in addi-
tion to the ordinary memory clear if the content in the memory
on the control PWB is broken because of PWB repair, etc. (In
the production stage, it is necessary to execute this in the last
process.)
Rapid key 10: Top adjust mode
As the method to adjust the top margin for printing, adjust top margin
adjusting VR on the PWB. If this mode is used at this time, adjustment is
possible without the printing test every time when VR is turned.
For the practical use, determine the adjusting value on the basis of the
old data, and adjust to the determined value in this mode. Then, check it
with the printing test.
