- Connectivity with the cont roller -

When a communication error occurs between
Silver and controller (the EZ-1 or CB-1), the
controller sends an error signal to t he m ain body.
The Silver sometimes does not send a response
signal to the controller and the contr oller stays in
the busy condition. (The LED on the controller
stays blinking until it is swiched off.)

This problem does not occur when the controller
is comunicating with the main body properly.
However, once any communication errors occur,
there is a possibility that this problem may occur.

With the new f irm ware, Silver can send t he
response signal properly even if a communication
error occurs.

- Error in the User Code mode -

Even when the User Code mode was enabled
with SP120, the machine could not be reset (to
enter the user code entry display) by pressing the
keys as explained in the manual.

The only way to reset it was to wait for the
automatic reset (the Autoreset mode) or switch
the machine off and on.

This bug has been solved in this version.

This change has been implem ented into the

Asian versions for Ricoh and NRG (#C231-23
and -29).

The new ROM can display Thai (in

combination with the new operation panel).
This language can be selected by setting
SP12 to 8. Due to the limit of the ROM
capacity, Japanese guidance was eliminated.
(“SP12-0” was for Japanese, and it no longer
functions in this version of the ROM.)

To display Thai, the oper ation panel must be

changed at the same time. The par t number of
the new operation panel assembly is #C231

The part number of the MPU was changed for
identification purposes. The function remains

PROBLEM

When an Elesys Controller is connected with the Silver and if the controller is turned on
before the Priport is turned on, the following symptoms will sometimes occur.

Type 1:

The LCD on the operation panel grays out.

Type 2:

Type 3:
Type 4:

The drum starts turning. The beeper continues beeping. In this case, the Backup
RAM on the MPU (for the SP mode data) is reset and all SP mode data return to
their default settings.

Some LED’s on the operation panel start blinking or stay on.
Just like Type 2, the drum starts turning and the beeper continues beeping.

However, in this case the Backup RAM is NOT reset.

CAUSE

This problem will not occur when the Priport is turned on first as explained in the controller
operation manual. However, if the controller is turned on first, the communication start signal
is sent and interrupts the CPU initialization process when the Priport is turned on.

There are three types of Elesys controller; i.e. CB-1 (the mid-range), EZ-1 (the low-end), and
SFX (the latest and network supported). Depending on the type of controller, the behavior of
the problem varies.

Our test results (the symptoms and problem occurrence ratios are on the next page. The
values show the number of problems that occurred when tested 50 times for each type of
problem (Types 1 to 4).

SOLUTION

New firmware has been released to prevent this problem. The part numbers and check sums
for the new EPROM’s on the MPU are as follows:

Machine

Destination

Asian version C231 5155

Others C231 5105

The suffixes for the part numbers for the MPU board has been advanced from C2315100-S
to -T, and C2315150-G to -H for the Asian version. This modification will be applied from April
1999 production.

If a Type 2 problem occurs, the backup RAM on the MPU (for the SP mode data) is reset. SP
modes that were changed by technicians and users will return to their default settings. All
counters in the SP mode will be cleared.

C231 5175 EPROM - 1M X8 150NS 1539

The following SP modes are specially important and must be returned to the original settings
if the RAM reset has occurred:

PROBLEM

The paper jam indicator is displayed due to slow timing of paper delivery. The paper delivery
motor, which is an independent motor for the delivery unit only, slows down and does not
feed the paper at the proper speed. (When this occurs, the delivery motor has a high
temperature.)

This symptom will occur often when continuous printing many sheets.

CAUSE

The bushings and the shaft have run out of oil, so there is friction between the shaft and the
bushings.

SOLUTION

When this problem occurs, lubricate the shaft [B] where the bushings [A] contact.
On the production line, lubrication has been added from October ’98.

PROBLEMS

The following problems occur:

• E-01 (the status code for the master cutting error) is lit.

• Master jammed in the cutter unit.

• A master clamping problem during the master making process.

No: RC231004

CAUSE

Moving the drum to an incorrect master clamping position causes a master clamping error.
This is caused when the drum turns from the home position to the master clamping position
to start the master wrapping process (around the drum). Then this incorrect positioning
causes the clamp to miss the master’s leading edge. The master continues feeding for
master making, but is not pulled while the drum turns. Consequently, the master bunches up
against the cutter unit, resulting in a master cutting error.

SOLUTION

Use SP mode 23 to adjust the master clamping position of the drum. Usually, the position in
SP mode is around "2." (If it is too large, a master clamping error will occur. And, if it is too
small, the clamper will hit the base of the master unit when it opens.)

Usually, this adjustment is prohibited since it is difficult to find the exact position. The manual
also states this in the SP mode table section.

When you use SP mode 23, carefully follow the adjustment procedure explained below.
The production adjustment process has been added from November ’98.

To indicate the factory setting (it may vary from one machine to another), a decal will be
attached behind the MPU cover from July 1999 production. The decal also indicates the
factory settings for SP22, 23, 26, 30, 31, 36, 37, and 38. These SP modes are sometimes
adjusted in the factory and must be checked when the MPU is replaced.

1. Turn off the main switch and unplug the power cord.

2. Remove the front cover.

3. Turn on the test switch. (To release the cover safety functions)

NOTE:

4. Plug in the power cord and turn on the main switch.

5. Access SP131 - 28 (Output mode - Drum Plot Stop) and press the Start key.

6. After the drum turns to the clamping position [A], look at the operation side of the drum.

7. Release the cable [B] from clamp [C].

8. Look at the drum flange spoke [D] inside the U-shaped cut out.

9. Mark a line [E] next to the spoke [D].

Don’t forget to return it to the normal setting after finishing this procedure.

How to use SP23 (Plot position adjustment)

The drum stopping position for master clamping can be changed within the range of 0 to 9
(10 steps).

Look at the drum flange’s spoke, referred to in step 8 of the adjustment procedure.

When the value is less than 5, the spoke is on the upper side.

• When the value is more than 5, the spoke is on the lower side.
