<Problem>

Auto service call (Hot Roller Down) may occur during sta nd by mod e.

<Cause>

TRC (Triac)1 and/or 2 on the PSU may be damaged (short ed ) in the field by severe impulse
noise or power supply drop out. (The TRCs switch the ac power supply to the fusing lamp
on/off.)
This may cause continuou s power supply to the fusing lamp an d this will genarate the above
auto service call condition.
(There are two safety circuits for the power supply to the fusing lamp . The safety circuits cut the
power supply to the fusing lamp.)

<Modification>

Change the capacitors (C8 and C9) to th e surg e killers (10 0Ω +0.01µF) to increase the safety
margin against unstable ac power conditions in the field.
This will be effective from Feb. 1994 production.

Background: Machines have been sent to cu sto mers after pre-installation and sent back to the
service center for repair.

Problem: Toner had spread inside the machin e du ring transportation.
Cause: Toner leaked from the development unit, the toner ca rtrid ge , or somewhere

in the toner path during tran sportation.

Preparation for transportation:

(1) Transportation withou t he avy vibra tio n

(Example: A technician should carry the machine with care.)

• F/L series fax machines:
The development unit can be connected to a CTM with toner.
However, the toner path under the CTM must be covered by some
adhesive tape. See the attached illust rat ion.

(2) Transportation with heavy vibration

(If a third party handles the transportation, follow this procedure.)

• F/L series fax machines:
Remove the development unit and the CTM fro m the machin e if toner
has been installed. They must not be delivered in the same box as the
machine, because they contain toner which may spill out. The toner
inside the machine must be clean ed away or th e toner path under the
CTM must be covered with tape.

• C series fax machines and others:
Remove the development unit and CTM (or Toner Cartridge) from
the machine if toner has been inst alle d, and clean the toner from

SYMPTOM:

Background on received and copied documents.

Cause:

Hot Roller failure as a result of not changing the Cleaning Pad at the 10K PM.
Failure to change the Cleaning Pad results in dirty Strippers and Thermostat and
then Hot Roller failure.
As the machine warms up from the standby temperature to the fusing
temperature, it is exposed to slight overheating before the temperature levels
off. This leads to softening of the Teflon layer on the Hot Roller. As a result, the
Teflon layer peels off in the areas where the Strippers and other parts come in
contact with it. Dirty Strippers and Thermostat put more stress on the Hot Roller and
cause premature Hot Roller failure.
Also, the dirty Thermistor causes the Hot Roller to overherat and fail prematurely.

FROM: Quality Assurance Center

Oct. 15, 1996

MODEL:

CSO, CRO, CS1, CFO,
CGO

A second cause can be a damaged (bent ) Thermistor from a previous service visit.
The damaged Thermistor causes the Hot Roller to overheat and fail prematurely.

SOLUTION:

Ricoh recommends replacing the Cleaning Pad at the 10K PM. However, this is
sometimes ignored. Realizing this, Ricoh will conduct the following modifications to
protect the Hot Roller from the failure mentioned above.

Hot Roller Kit:

The hot rollers shipped from the SPC in Japan will be replaced by the

Hot Roller Kit in July.
This kit will be comprised of the following: Hot Roller, Cleaning Pad, Thermistor,
Thermistor Bracket, Screw, Strippers (2), Stripper Springs (2) and Installation Sheet.
The individual Hot Roller will be no longer available. The Cleaning Pad will
continue to be a Service Part.

Ricoh recommends change of the above modified parts and Cleaning Pad when the failed
Hot Roller is replaced with the new one.

NOTE
(A): Please refer to the following instructions and fix the cover to the fusing unit
and check that the harness is not pinched before installing the fusing unit in the
machine.

If the metal wire of the harness contacts the thermistor bracket, a no power
condition may occur. Please check the thermistor harness if this occurs.

The year 2000 issue was explained in RTB No. General-011B.
That RTB explains only the technical matters of what will happen after the year 2000 in

some models, and the countermeasures.
At this time, we would explain how to talk with customers about the year 2000 issues

related to fax machines.

Basically, we can say to the customers that there is no major issue reated to basic
operation after the year 2000, and they don't need to take any preventative action before
the year 2000.

The only thing that the customers need to know is that the following operations will be
changed after the year 2000.

customers are using this function.)
Please recommend adjusting the timer on Sunday if the customer can do it.
If they cannot do it on Sunday, the ROM should be changed to the new one.
The new ROM includes the countermeasure for the above A) also.

2. K200 (FAX7000L)

A) Adjustment of the year
First, please do not forget to inform the customers that they don't need to do anything if

they do not go into the clock adjustment mode.
A-1) For the year 2000

Set the clock to 11:59 PM (or 23:59) on December 31 1999, and wait for one minute.

①

The year changes to 2000 automatically, then set the current time.

②

(Do not change the year.)
A-2) For the year 2001

Except AF0

••••

After the above step ①, set the clock to 11:59 PM (or 23:59) on December 31 2000,

③

and wait for one minute.

The year changes to 2001 automatically, then set the current time.

④

(Do not change the year.)
A-3) For years 2002 and later
Repeat the same procedure as above.

If the customer switches off the machine after the year 2000, the year displayed re turns to

1988. In this case, follow the above procedure to adjust the clock.

B) Send later mode
Please notify the customer that they should not use send later mode on December 31st

1999, if the transmission will be done on the next day.

If the customer cannot guarantee that they will follow this advice, the ROM should be
changed.

ROM writing procedure for K200 ROMs

1. ROM Writing
This will vary depending on the ROM writer buffer capacity.
This is an example with a buffer RAM capacity of 512KB.
During the first load, 512KB is sent.
During he first load, 0H~7FFFFH can be loaded.
During the second, 800000H~FFFFFH can be loaded.
Since the K200 is 1MB, the sending is completed after 512KB worth has been sent
twice.

First Time
1-1) Transfer to the ROM writer.

When the buffer RAM capacity is 1MB, the RAM writing is as follows.
1MB can be sent during the first load.
OH~FFFFFH can be loaded.
Since the K200 is 1MB, it can be transferred all at once.

Problem found
Most models, except the following models, will not experience any problems.

1) AFO (FAX [phone], NRG 9620, Infotec 3301/3305, Nashua F492)
CSO (FAX [phone], NRG 9660/9661/9662, Omnifax L40/41,
Savin FAX [phone], Infotec 3660)
CS1 (FAX 3500L,NRG 9665, Omnifax L46, Savin FAX 3670)
CRO (FAX 2500L/2600L, NRG 9650, Omnifax L42, Savin FAX 3630, Infotec 3661)

a) The day of week, that appears on the display only in the clock adjustment

mode, is returned back to SUNDAY whenever the clock adjustment is done
after the start of the year 2000.

So, the programmed weekly timer does not work correctly. (AFO’ s do not

have the weekly timer.)

If the clock adjustment is not done after the start of the year 2000, the date and

the day of week is kept correctly.

b) Clock adjustment is available only for the year 91 through 99. The other years

cannot be set. (Month, day and time can be adjusted.)

Problems found
Most models, except the following, will not experience any problems.

1) AFO (FAX [phone], NRG 9620, Infotec 3301/3305, Nashua F492)

CSO (FAX [phone], NRG 9660/9661/9662, Omnifax L40/41,

CRO (FAX 2500L/2600L, NRG 9650, Omnifax L42, Savin FAX 3630, Infotec 3661)

a) The day of the week that appears on the display only in the clock adjustment

mode is returned back to SUNDAY every time the clock adjustment is done
after the year 2000.

So, the programmed weekly timer does not work correctly. (AFO does not

have the weekly timer.)

If the clock adjustment is not done after the year 2000, the date and the day of

week is kept correctly.

b) Clock adjustment is available only for the year 91 through 99. The other years

cannot be set. (Month, day and time can be adjusted.)

Date:

15-Jan-99

a) Clock adjustment is available only for the years 88 through 99. The other years

cannot be set. (Month, day and time can be adjusted.)

b) The send later mode does not function (no calling happens) if time passes into

the year 2000.
No report is printed and the rest of the message in the memory is not cleared
automatically, but it is cleared by user operation.

c) Automatic re-transmission is not done if the year 2000 starts in the interval after

the transmission failure.
The rest of the message in the memory is not cleared automatically but it is
cleared by user operation.

d) The displayed date is reset and turned back to ‘88 in the event of a power

failure after the year 2000.

e) The day of the week will be wrong if the clock or date information is

adjusted after the year 2000.
