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.

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.

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.

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

SYMPTOM

Low image density on copies made by low CV machines around 20 to 30K after
installation.

CAUSE

The fusing fan motor stops when the low power timer runs out (60 s) and the machine
enters Energy Saver Mode. Because the fusing lamp remains on in order to maintain hot
roller temperature, the temperature of the areas surrounding the unit rises. The resulting
heat can damage the toner that is stored in the bottle above the fusing unit, causing some
of the toner’s constituents to separate out. The altered toner is then sent to the
development unit and is mixed in with the developer, causing developer chargeability to
drop. This results in low image density on copies.

This heat damage occurs on low CV machines, as the toner remains in the bottle for
extended periods of time.

ACTION

Newly installed machines:

Please upgrade the BICU firmware to ver 3.5.1 at installation.

Field machines which have no low ID problem:

Please upgrade the BICU firmware to ver 3.5.1 at the next field visit.

Field machines which have a low ID problem:

1. Upgrade the BICU firmware to ver 3.5.1.

2. Replace the developer.

3. Replace the toner bottle.

4. Clean the toner from the toner hopper.

COUNTERMEASURE

1. Firmware:

The off-timing of the fusing fan motor has been delayed, so that it will remove the hot air
around the toner bottle.

2. Hardware:

As an added measure, a heat insulator will be installed between the front frame of the

scanner unit and the toner bottle to ensure that the toner is not damaged, even if the
internal temperature should rise.

SYMPTOM

One of the following SCs is activated when the power is turned on by the weekly timer or
by the operation switch (upper right of the panel):

SC124: Scanner motor encoder error SC501: 1st tray lift malfunction

SC335: Polygonal mirror motor error 1 SC502: 2nd tray lift malfunction

SC362: Hard disk detector error SC503: 3rd tray lift malfunction

SC493: Exhaust fan motor lock SC520: Duplex jogger motor error 1

SC494: Fusing exhaust fan motor lock

CAUSE

When the power is turned on, the supply of voltage through the 24V line is slow.

FIELD ACTION

The occurrence rate is predicted to be extremely low because the range of tolerance for
the start-up current in 220V machine PSUs is approximately +/- 20%. If you receive reports
of any of the SCs mentioned above, please do the following procedure:

1. Set the machine to turn off with the weekly timer.

2. After the machine has turned off, turn the operation switch on and off at least ten times.

3. When any of the SCs listed above is activated, please replace the PSU board.
If none are activated, please check other possible causes for the SCs reported.

Note: The PSU boards themselves cannot be modified in the field. Therefore, all PSUs

now in service parts stock are either modified units or previous units that were found
to have no problems (see below for details). The part number for the PSU has not
been changed.

enough.

ACTION

1. Recommend customers to set the Edge Smoothing function to the OFF position in

the printer driver.
The default setting of the Edge Smoothing function for each driver language and
printer controller type is as follows:

Driver Language Controller Type A Controller Type B

PCL5e ON OFF
PCL6 ON OFF
PostScript3 OFF OFF

2. Change the printer dot edge parameter in the printer SP mode (Printer SP – Settings –

Printer Dot Edge Parameter) from “Normal” (default) to “SP mode”.

Note: With this change, the print line width can be thickened. This change is valid only

when the Edge Smoothing function is set to “OFF”.

3. Change Copy SP2114 (Printer dot edge parameter setting) to the original settings.

SP Number Original Setting

SP2114-1 7
SP2114-2 7
SP2114-3 11
SP2114-4 7

4. If the customer wants an even thicker line width, change Copy SP2114 (Printer dot

edge parameter setting) from the original settings to the thicker settings.

SP Number Original Setting Thicker Setting

SP2114-1 7 10
SP2114-2 7 10
SP2114-3 11 15
SP2114-4 7 10

Note: Do not set any other combinations of the four settings other than in the above

table. Otherwise, an unexpected image appears on printouts.

This SP is valid only when the Edge Smoothing function is set to “OFF” and the
Printer Dot Edge Parameter in the printer SP mode is set to “SP mode”.

SYMPTOM

SC729 is displayed, or the mainframe does not detect the finisher.

CAUSE

1. Electrical noise generated by the drive motor affects the initial check routine of the

punch drive board firmware, such that the motor reset signal is constantly sent out. The
only units on which the symptom may occur are the USA two-punch-hole and European
four-punch-hole units.

2. The two screws securing the heat resistor to the IC on the punch drive board come

loose. As a result, the temperature of the IC becomes too high.

SOLUTION

1. The software has been changed so that the drive motor reset signal is deactivated at the

proper time, even if electrical noise occurs.

Production units:
The ROM on the finisher main board has been changed from the beginning of
September 2000 mass-production, and on some units from August mass-production.

Old ROM P/N: B302-5103F
New ROM P/N: B302-5103G

Listed below are the serial numbers for August production finishers that contain the new
modified ROM.
Note: These units are marked with yellow, circular labels next to the bar code on the

1. SP5009 (Language Selection) Deleted

This SP mode is no longer necessary since the display language can be selected using
Language Priority inside User Tools.

2. SC990 Misdetection (Taiwan machines only)
Symptom Corrected

SC990 occurs when the document server key is pressed. The cause was determined to be a
bug in the software.

3. New Items Added to Output Checks (SP5804)

The following items have been added to the output check for the tandem tray:

No. Description

22 Right Tray Lock
23 Left Tray Lock

4. Incorrect Drum Unit Installation
Feature Changed

There is no response when the Start key is pressed, and the machine displays “copying”. This
was because the drum unit had not been set properly. The new software version allows the
machine to start the job even if the drum has not been set properly, however this will be
indicated by an image quality problem on the printout. Therefore if this occurs, check to see if
the drum has been set properly.

5. Page Numbering for Duplex Copying
Feature added

Even when Center has been selected for the page numbering position and fine adjustments
are made left/right, the actual printing positions on the front and rear sides will match.

6. Scanning Speed Increased

The Document Server scanning speed has been increased from 60 to 70 spm.

7. SC Display Error (SC740 instead of SC720)

Symptom Corrected

For a finisher motor failure, the machine displays SC740 when it should display SC720. In
addition, a SC740 occurrence is logged in the machine history.

Note: SC740 is an SC error code for the A763 Booklet Finisher.

8. Paper Exit Orientation Error
Symptom Corrected

Normally when switching from platen to DF mode, the copy paper exit orientation will be
changed so that the front side faces up. However, when switching over to Batch (SADF)
mode, the machine does not make the change (i.e. paper is still fed out with the rear side
facing up).

Note: The pre-paid card and key counter have not been fully tested with the Mojito by Ricoh,

because they are not official options for the Mojito. However, the following items (1 and 2)
have been improved as per a field request.

1. Error when connecting the pre-paid card connector to the mainframe 4-pin key counter
connector

Symptoms

1) The copier only counts up once for every 2 copies made.

2) When the key card has been set in the machine and the main switch turned on, the machine
does not detect the card unless the card is taken out and set again.

* Other symptoms are possible. The actual symptom can vary depending on the type of card

used.

2. Counter error after the key counter is removed and a jam occurs
Symptom

If a jam occurs after the key counter is removed during a copy job, the counter value is less than
the actual number by 1 when copying starts again.

3. SC337 Logged by Mistake
Symptom

SC337 is not displayed but is recorded in the logged data.

Cause

There are cases where the 24V line is cut before the 5V line when the main switch is turned off,
causing SC337 to occur. Since this occurs when the machine is being turned off, there is no
SC337 display, and an error is logged by mistake.

Solution

To prevent SC337 from occuring at power off, both the display and logging of the error will be
done at a fixed time after occurrence (200ms). This will allow time for all power lines to drop to
0V, thus preventing misdetection of SC337.

1. SC990 when printing out the SMC sheet: Polish language only
Symptoms

When SP5590-1/-3 is used to print out the SMC sheet and Polish has been selected as the
display language, the wrench symbol lights up and an SC990 error is logged.

2. SC990 at copy start when ID sensor Vsg=0V
Symptom

SC990 occurs if copying is initiated when the ID sensor Vsg is at 0V. The condition is cleared
when process control initialization is performed. However, when the power is turned off and then
on again, it will always occur when copying is initiated.

3. Diagonal white lines/image shifting with SMC sheet printing
Symptom

When printing out the SMC sheet or counter data printout onto 81/2 x 11 lengthwise paper,
diagonal white lines appear on the copy or the image data is shifted.

4. PM alert display not displayed at PM timing
Symptom

The PM alert is not displayed when the PM counter reaches its set value.

5. Margin adjustment setting error - Interrupt key
Symptom

When the interrupt key is pressed and the margin adjustment settings are changed for a new
job, the machine returns to the original copy job modes/settings, but does not return to the
original margin settings.

6. Default setting error when performing Memory All Clear on models for China
Symptom

When SP5801 (Memory All Clear) is performed on models for China, the default for the third
paper was displayed as B4, instead of what it should have been (A3). The default value (A3) will
now be correctly set.

Important:

In addition to turning off the main switch, please be sure to take the following precautions
when replacing the NVRAM.

1. Loss of ALL data stored on the NVRAM.

The NVRAM contains an internal battery, so please observe the following two
guidelines when replacing the NVRAM:

1) Before replacement, the technician should touch a metal portion of the machine to
eliminate the possibility of a static electricity buildup.

2) Do not place the NVRAM on an object made of conductive material.
This will cause a short, resulting in the loss of all the data inside.

2. Physical damage to the NVRAM pins when removed.
The insertion and removal of the NVRAMs are the same as for the EPROMs. However,
since the NVRAM’s casing is made of a resin (plastic), it is necessary to take extra care
when removing them so that the casing doesn't break.

1) When removing the NVRAM, insert a small, flat-head (standard) screwdriver into
the space between the NVRAM casing and the RAM socket (at the ends where there
are no pins), lift the RAM up on both ends with the screwdriver, and finally take it
out by hand.

2) When inserting the NVRAM, it is important to first make sure that all of the pins on
both sides have been properly set in their holes, and then to push the pins in all the
way.

SYMPTOM

During copying, a jam occurs in the inverter section.

CAUSE

Some A2294472 upper exit guide plates contain an extra rib due to a molding error. This
rib can sometimes interfere with the exit guide pawl and cause a jam.

The occurrence rate for the interference is 0.2%. Further, the occurrence rate is slightly
less after the plate is opened and closed, as the plate and pawl both have a range of
movement front to rear of 2mm, making it very unlikely that the two parts would return to
the same positions.

SOLUTION

To ensure that similar molding errors do not occur, the mold for the exit guide plate has
been changed from the middle of February 2001.

SYMPTOM

The Motor Joint Gear of the toner bottle holder is worn down, causing noise and uneven
rotation.

Note: This symptom has a high tendency to occur after the total counter reaches
1000K.

CAUSE

The amount of grease applied to the gear during production was not enough to prevent
premature wearing.

SOLUTION

An increased amount of grease has been applied to the gear at the factory since the first
lot of May 2001 production.

For field machines produced before May ’01 production:

As preventative action for this symptom, grease should be applied to the entire contact
surface of the Motor Joint Gear (see Application Procedure below). This countermeasure
will ensure that the gear will reach its specified lifetime.

Note: Please make sure that grease is applied at the next PM visit or inspection.

1. Fusing jam reset conditions changed
Symptoms

To ensure that fusing “D” jams are properly cleared, the software has been changed so that the
jam condition does not clear unless the fusing unit is removed and re-inserted. Previously, the
condition could be reset with power off/on if the sensor inside the unit did not detect the jammed
paper.
Note: Please instruct customers that after removing the jammed paper around the fusing unit, it
is also necessary to remove and reinsert the fusing unit and check for any jammed paper inside
the unit as well.

2. PM Call Display Error
Symptoms

If the main power is turned off/on while a PM call message is displayed, the message and PM
alert condition are cleared.

3. LCT paper size selections added to SP5019 (Tray Paper Size Selection): A4R and LTR
Field Request

To enable selection of these sizes, it is necessary to install the LG Kit and change the size
settings of the side and end fences.

4. OHP/Finisher Hole-Punch Change (B312)
Field Request

Software changed so that OHP transparencies cannot be used with the hole-punch feature of
the finisher (B312).
When selecting OHP transparencies with the # key (bypass tray feed) and then the hole-punch
function, the machine disables operation and a warning display appears on the panel.

5. SC 337 detection conditions changed

SC 337 detection conditions changed so that it will not be triggered by such factors as electrical
noise while in standby mode.

6. SC300 detection conditions changed:

To minimize unnecessary SC300 occurrences, the SC300 detection method for charge leaks
has been changed as follows:

Old: The counter for number of leaks is cumulative for the entire on-off charge output interval.
New: The counter is reset every 500 ms.

7. Printing Doesn't Start in Interrupt and Low Power Modes
Symptoms

Copying not possible when the machine enters Low Power Mode from the Copy Interrupt
screen, and then recovers to Ready status (same screen).

Order of operation:

Copying in interrupt mode

The machine enters low power mode
Auto-response brings the machine out of low power mode (still in interrupt)
An original is set in DF, the Start key is pressed and the original is fed
The Start key alternates between green and red, and copies cannot be made.

SYMPTOM

The toner recycling pump locks.

CAUSE

The quality of recycled toner gradually decreases, eventually hardening and clumping to
the point where the Toner Recycling Pump is no longer able to effectively circulate it.

Note: In particular, this occurs when the temperature of the machine’s surroundings is
high, such as in relatively high-temperature environments or when there is a minimum
amount of free space around the machine.

SOLUTION

Replace the Pulley and Timing Belt with the modified parts listed below, which will
effectively increase the drive power of the pump from 225rpm to 400rpm.
