[Notes]
Be sure to carry out simultaneous exchange for SIC-ROM, M-ROM and IMC-ROM.1.
Although simultaneous exchange is recommended for the other ROMs there is no problem even 2.
if this does not take place.
BSINo. G00B931 Page 2
When Ver.130 of SYS-ROM/Ver.10 of M-ROM/IMC-ROM is changed, be sure to perform [Work 3.

d. Press the "2" key, the START key and INTERRUPT key in that order.
e. After the message "SCAN COMPLETED" appears, press the START key.
f. After the message "COMPLETED" appears, press the STOP key.
(3) [For PHOTO made]
a. Key in code "5", then press the SETTING key. The test chart is output.
b. Set the test chart on the original glass.
c. Key in code "643" and press the START key. Wait a few seconds.
d. Press "3" key, the START key and INTERRUPT key in that order.
e. After the message "SCAN COMPLETED" appears, press the START key.
f. After the message "COMPLETED" appears, press the STOP key.
4. Turn off the main switch.
*Note1 Initialization of image parameters
When initialization of the image parameters is performed, the following adjustment value will
be changed to the initial value. Please readjust if needed.
Please refer to page 1-73 from page 1-69 in the Service Handbook.
1-8. Density Adjustment (08/550-589)
1-9. Color Balance Adjustment (08/779-798)
1-10. Offset Amount for Processing Background (08/698/717)

SYS-ROM
[130 --> 140]
1. The setting code (08/217) of the cassette loading status has been added as follows.

(1st, 2nd, 3rd, 4th cassette)
2. Mistaken detection in the automatic paper selection (APS) mode when the original is placed on the
glass has been corrected as follows.
In order to correct this right after turning on the power switch, the Software has been changed to
display the initial screen and reject the APS function during the warming up.
3. The message "Wait Fuser Stabilizing" has been added during the temperature adjustment of the
fuser.
4. The "YMCK" icon was detected from the test pattern selection screen.
This is because 04/230, 04/231, and 04/234 test patterns are prohibit when using the four color
mode (YMCK).
04/230 (gradation check pattern of 2 pixels standard)
04/231 (gradation check pattern of 3 pixels standard)
04/234 (halftone)

6. The copy image quality in the photo mode and the AI mode (optional) and the accuracy of
the automatic gamma adjustment have been improved.
7. The Fiery scan mode with Z4 has been changed from one to two scanning operations.
8. The following code has been added on the setting mode (08).

This code is for making printing continue from the printer, when the copy operation is interrupted,
due to running out of paper.
9. The software related to the Z4 controller has been improved.

1. The icon of "2 ->1 (single-sided copies with two-sided originals)" and "2 -> 2 (duplexing copies with
two-sided originals)" in the duplexing setting mode has been corrected.
2. A density check pattern (04/256) in the test print mode (04 mode) has been added.
Setting Mode (04)
Code Type of test pattern Remarks Paper size

Density check pattern None A3/LD
BSINo. G00B931 Page 4
3. The following has been changed. When the AI board is not installed, the "AI" icon is not indicated
in the 05 test copy selection.
4. In a automatic calibration of gradation, please refer to the unpacking instructions, "Press 2 key, the
START key and INTERRUPT key in that order" is mentioned.
However when the front cover is opened and closed before pressing the INTERRUPT key, entry
with the digital keys will be permitted. This software bug has been corrected.
5. Though F13 error occurs rarely, the software bug has been corrected.
F13 means a communications error between the System-CPU and the Main-CPU; however this is
not listed in the Service Handbook.
6. The software related to the Z4 controller has been improved.
M-ROM
[10 --> 11]
1. In order to improve the halftone image at the leading edge, the value of the transfer high voltage
has been changed as follows.
Current New
Paper
0 3mm 0 3 11mm
on(100%) on(100%)
off (0%) off (0%)off (0%) on (80%) off (0%)
2. When the door switch is closed forcibly while opening the front cover, the fuser unit is removed
and reinstalled, sometimes the machine control is locked up. This firmware bug has been
corrected.
3. The output check function (03 mode) has been corrected as follows.
code 03/133; Color registration sensor LED (front) ON
code 03/183; Code No.133 function OFF
code 03/134; Color registration sensor LED (rear) ON
code 03/184; Code No.134 function OFF
code 03/114; Image quality sensor shutter solenoid ON
code 03/164; Code No.114 function OFF
4. After performing the 05/879 function (Automatic initialization of IQC), when opening and closing
the front cover, sometimes the machine control is locked up with the "warming up" indication.
5. When the fuser temperature becomes extremely high, the main switch is supposed to be turned
off forcibly. But the current software does not work correctly. This firmware bug has been
corrected.
6. When setting the duplex copy mode with two-sided originals (2 - 2) selected and the copy quantity
"3", if the third sheet is jammed in the exit area as an E02 error and this is removed from the
machine, sometimes the machine control is locked up.
BSINo. G00B931 Page 5
7. An auto cassette detection function has been added in the cassette loading status. (08/217)
For example, when the third cassette is newly installed, the machine recognizes that the third
cassette is now installed when the power is turned on and then the value of 08/217 is changed as
the default.
[11 --> 12]
1. When making an OHP copy from a high image density original, the image is lacking at the leading
area 0~30mm on the OHP sheet. This firmware bug has been corrected.
2. The value "5" has been added into the cassette loading status as follows. (08/217)
Setting Mode (08)
Code Name Default Allowable

15: Auto cassette detection
6,5 ~ 14: Change value to "3" forcibly.
(1st, 2nd, 3rd, 4th cassette)
3. When making a test copy in the 04 mode, the drum life counter "08/840,841,842,843" and
developer-material counter "08/844,845,846,847" did not count up correctly.
Also these counters did not count up correctly in the mono-color copy.
These firmware bugs have been corrected.
1
4. The value of "Large size double counting" (08/802) was not read correctly, namely the code was
indicating the wrong value.
But the double counting operation in the copy mode is correct, and the writing value operation of the
code is working correctly. This firmware bug has been corrected.
5. When a feeding jam occurs to the last sheet and the jammed sheet is removed from the machine,
it tries to feed the paper from the cassette in spite of there being no more paper. The feeding jam
occurs again. This firmware bug has been corrected.
6. The indicated value of the image quality sensor in the 03" mode has been corrected.
7. The firmware related to the Z4 controller has been improved.
IMC-ROM
[10 --> 11]
1. The density of the grid pattern (04/204) in the test print mode has been slightly changed so as to
become light.
2. The test print pattern data (04/204) has been changed.
3. In order to improve the IQC, the ON/OFF timing of the transfer high voltage for the IQC test pattern
formed on the transfer belt has been changed.
[11 --> 12]
1. When the 03/280 function (Y-Laser ON/OFF) is executed, Y-Laser is turned on and off
periodically.
03/281(M),282(C),283(K) functions are the same as for Y-Laser. These firmware bugs have been
corrected.
BSINo. G00B931 Page 6
2. In the "03" mode ( input check mode), the value of the image quality sensor is indicated wrongly.
(Please refer to page 1-13 in the Service Handbook for details.)
3. The firmware related to the Z4 controller has been improved.
SCM-ROM
[06 --> 07]
The leading void has been improved to be more accurate in the enlargement copying (X-Y zoom).
AI-ROM
[10 --> 11]
Advanced Image ROM (AI-ROM)
1. The image discrimination has been improved to render it more accurately.
2. The processing time for the image discrimination is reduced.
