Background
The mail box (CS360) is currently an optional item for the SP5/SP5L (A229) and NAD
30S/30/40 (A230/A231/A232), and can also be installed on the Mojito (A292/A293).
The A292/A293 has a faster process speed than the A229 and A230/A231/A232. New
software (G909 0339 A) is necessary to allow the CS360 to work smoothly on the Mojito.
Interchangeability between Main Frame and CS360
The new software can also handle the A229 and A230/A231/A232 perfectly.

the relevant Service Manual and Parts Catalog information below.
The purpose of this kit is to make it possible to feed 8 1/2” x 14” sized paper from the LCT
(A698: RT37). Please note that when the kit is installed, 8 1/2” x 14” is the only size that
can be fed from the LCT.

8-bit data
The CCD converts the light reflected from the original into an analog signal. The CCD line
has 7,500 pixels and the resolution is 600 dpi (23.6 lines/mm).
The CCD has four output lines: OS1, OS2, OS3, and OS4. OS1 and OS2 are for the first
half of the scan line (Non-operation side), and OS3 and OS4 are for the last half of the
scan line (Operation side). There are two analog processing ICs; one handles the first half
line (OS 1 and OS2) and the other handles the last half line (OS3 and OS4). The analog
processing IC performs the following operations:
1) Combines the odd and even signals into one line signal.
2) Adjust the black reference level of each CCD output channel.
3) Amplifies the analog signal from the CCD.
After the above processing, the analog signals are converted to 8-bit signals by the A/D
converter. This gives a value for each pixel on scale of 256 grades. Then, the two 8-bit
signals are sent to the BICU board through the LVDS (Low Voltage Differential Signaling).
The LVDS is a noise-resistant interface.

Note:
1) The LCDC ROM A2935203C is required for BICU firmware version 3.1 (A293 7564,
A293 7565 and A293 7566).
2) Version 3.1 requires the printer controller.
1. Language
The following items have been changed from English to the language selected:
1) Stamp Setting
Note: For Portuguese and Polish, the Stamp setting is still displayed in English.
The correction for this will be included in the next software update.
2) Language Priority button
2. A3/DLT Double Count corrected for copy counter and printer counter
When making A3/DLT copies, the copy and printer counters do not count up by 2,
even if A3/DLT Double Count has been set.
Note: The total counter correctly counts up by 2.
3. Key counter in connect copy mode
When the key counter is removed from the machine during a copy job in connect copy mode,
both copiers will stop and display “paper jam”.
4. Slip-Sheet Mode
It is possible to select “Copy” or “Blank” from the operation panel in Slip-Sheet Mode.
5. Mailbox
The software has been modified so that the correct picture indicator is displayed when the
mailbox door is open.
Note: The incorrect indicator was displayed when the Mailbox was the only option installed.
6. Conditions for reverse drum rotation
To reduce the load on the units around the drum, the cycle for reverse drum rotation has been
changed as follows:
New: The drum is turned in reverse at the end of a copy job if the cumulative running time for
the drum has reached or exceeded 4 minutes.
Old: The drum turns in reverse at the end of every copy job.

1. New Copy Feature and SP Mode (SP5971) Added
1) New Copy Feature: Enhance Density Mode
This feature has been added to ensure that image density does not drop while making
multiple copies of originals with a high percentage of solid black areas.
To set thebeffective original density and number of copies for multi-copy mode, use SP5971
(see below).
To add the Enhance Density key to the display panel and to control the level, do the
following procedure:
(1) Press the User Tools/Counter key.
(2) Press the Copy/Document Server Features Key.
(3) Open General Features, screen 3/3.
(4) Select one of the Shortcut Keys from F1 – F5.
(5) Register the Enhance Density Key.
(6) Open General Features, screen 1/3.
(7) Select the setting for Enhance Density Level.
High: Vt+0.6
Medium: Vt+0.4 (default)
Low: Vt+0.2
2) New SP Mode: SP5971 (Enhance Copy Setting):
The following settings apply to Enhance Density Mode:
Mode No. Function Setting
5971
2. Paper jam in finisher (B302) + Printer Mode
Depending on the printer mode settings, jams can occur in the finisher when continuous print
jobs are shifted alternately between the proof and shift trays.
The machine cannot switch fast enough between the two paper paths in these cases. The
interval between jobs has been slightly increased to allow the machine enough time to make
the switch.
3. Fusing Unit Fan Motor Off-Timing Change
To ensure that hot air around the toner bottle is removed properly, the fusing unit fan motor
will be kept on whenever 24V is being supplied.
Therefore, it will turn off only when the main switch or operation switch is turned off or when
the machine is shut down by the Auto-Off function.

Retrofit information
Some booklet finishers (A763) may exhibit the following problem. Please check the
machine at installation or at the next customer site visit.
SYMPTOM
When making copies in staple mode, an IC on the finisher board shorts and SC740 is
displayed. After the main switch is turn off and on, a jam is indicated.
CAUSE
The cable of the guide plate motor is caught between the guide plate unit and frame. In the
worst case, the cable covering peels off and the +24V line is shorted to ground. These two
factors combine to cause the finisher board to be damaged.
ACTION
[A]
1. Hold up the proof tray and open the top cover [A].
[B]
2. Unhook the upper rear cover [B] and remove it (3 screws).
