Not used the camera for some time. When I try to take pictures I get the Error message Err 99. Shooting is not possible.Turn the power switch to <Off> and <On> again or re-install the...


hi the err 99 usually stands for shutter problem. however, there are several different causes. The first is defective shutter unit, second is defective power diaphragm unit in lens, and main PCB defective. You have to bring to your local repair shop. they would charge you around $65 to $235 depend on what it really cause problem. you can verify lens or body problem. try to operate without lens if still see err 99 when you push button. then it is body problem... Good luck with you...

Hiyou might have a problem of either main pcb or power control pcd (dc/dc convertor). it is common but it cost. It cause usually come from loosen screw going around inside and short. If it is lucky, then your unit would just a fuse brown. If not, it has to change main pcb and all of computer adjustment is involved. Your local repair shop would charge you around $65 to 235.

When The battery on my Canon 400d goes flat it loses the date and I have to re set it. I didn't need to do that until recently.


There is a small backup battery in the main battery compartment. I believe the XTi uses a CR2016 battery. It provides backup power to maintain the camera's settings when the main battery is removed.

Hi - We have an error code on a Canon Model 2800 : E000001-0002 Any ideas on how to fix the problem? Thanks! Paul


E001
0000 The main thermistor detects 250°C or higher.
0001 The main thermistor or the sub thermistor detects overheating (hardware
circuit detection).
0002 The sub thermistor detects about 295°C or higher.
Main cause The fixing film unit is faulty (i.e., the thermistor has a short circuit). The
main power supply PCB is faulty. The DC controller PCB is faulty.
Caution To clear the error, execute the following in service move:
COPIER>FUNCTION>CLEAR>ERR.
Action
1. Fixing film unit
Check the interval between pin 1 and pin 2 and between pin 3 and pin 4 of
the connectors (4-pin) of the thermistor for electrical continuity. Is it 0 ?
(short circuit)?
YES: The thermistor has a short circuit. Replace the fixing film unit.
REF.
If the thermistor has a short circuit, the indication in service mode
(COPIER>DISPLAY>ANALOG) will be as follows from the start: FIXC=250°C
for the main thermistor; FIX-E=310°C for the sub thermistor.
2. Main power supply PCB, DC controller PCB
Try replacing the main power supply PCB. Is the problem corrected?
YES: End.
NO: Replace the DC controller PCB.


BUT FIRST: under service mode *28* copier, function, clear , err turn off and on maybe it will work.If it works check that you have good air flow around the copier.

Error261 in canon copier


E261
0000 The intervals of zero-cross signals deviate from the tolerance range while
the fixing heater is supplied with power.

Main cause The wiring is faulty (short circuit, open circuit). The main power supply
PCB is faulty. The DC controller PCB is faulty.

Making Corrections
1. Connectors
Are the connector J205 on the main power supply PCB and the connector
J308B on the DC controller PCB securely connected? (zero-cross signal:
J205-7 <-> J308B-1)
NO: Connect the connectors securely.

2. Main power supply PCB, Main controller PCB
Try replacing the main power supply PCB. Is the problem corrected?
YES: End.
NO: Replace the DC controller PCB.

Hi, i have 2pcs of canon iR2016 Digital copiers which displays error codes of E246 AND E247. these errors are not in the service manual, please help


Sir i am a Canon trained tech. I just checked our website and my service information. I found the following. I suspect someone has been working on these machines or swapped some parts around.

Page 1 of 2
MODELS AFFECTED / SERIAL NUMBERS AFFECTED:
Digital Copiers, Including All imageRUNNER Products
SUBJECT:
Information About The New Soft Counter Circuits
GENERAL TECHNICAL INFORMATION
GENERAL:
This Technical Publication presents information about the new Soft Counter circuit that replaces the mechanical counter
used in the past. There are three (3) PCB’s associated with the new Soft Counter circuit; the Counter Memory PCB,
Main Controller PCB and the Serial Number PCB. A description of their function is provided below. Use this
document as a reference for current and future models that use the Soft Counter circuit.
Counter Memory PCB
On the latest Canon digital copiers, such as the imageRUNNER 5000, imageRUNNER 8500 and imageRUNNER 2200
series, there are no mechanical counters. Instead there is a Counter Memory PCB. This PCB is usually mounted on the
Main Controller PCB with one screw. The Counter Memory PCB is imprinted with the serial number of the machine
the first time power is turned ON and cannot be moved to another machine. Attempting to do so will generate an E246
error code. In the event of a Counter Memory PCB failure, a new one from stock (see Note 4) can be installed into the
machine. At that point the Main Controller PCB will transfer its present total count as indicated in “Counter Check” on
the control panel (recorded the last time power was turned OFF) to the new Counter Memory PCB and the total counter
will increment from that count on. Never attempt to operate a machine without the Counter Memory PCB
installed!
This may generate an E245 code, which can only be cleared by “zeroing out” the Main Controller PCB by
one of our A.P.R.F.’s (Authorized Parts Repair Facilities).
Main Controller PCB
The Main Controller PCB, aside from performing other tasks, retains the total count by means of SRAM with a battery
back up after power has been turned OFF. If, however, the Main Controller PCB has been replaced with either a new
one or a used one, it will read in and record the total count from the Counter Memory PCB retained the last time power
was turned OFF. The total count will then increment from that count on.
Note 1:
Even though the total count will be the correct value for that machine after replacing the Main Controller, the soft
counters in Service Mode will not. If a new Main Controller was used for the replacement, then all soft counters in
Service Mode (service counters in “Counter Mode”) will be zero. If, on the other hand, a used Main Controller was
used for this replacement, the soft counters previously recorded on that PCB would be shown. At that point it is
advisable to clear these values in Service Mode using Function>Clear>CNT-MCON.
All Main Controllers sent to our A.P.R.F.’s for repair will be “zeroed out” before being sent back to the dealer.
Page 2 of 2
GTI-T151
04-30-02 GT I
Note 2:
The Counter Memory PCB and the Main Controller PCB should never be replaced simultaneously!
This will
generate an E354 code and assistance from the Canon Reseller Technical Support Center Hotline will be required. If
the Main Controller is sent to one of our A.P.R.F.’s for repair, you must remove the Counter Memory PCB
before sending it out!
Failure to do so will only increase down time for your customer.
Note 3:
If the Main Controller PCB is replaced, ensure that connector J1023 is connected. If it is not, an E350 will be
generated.
Serial Number PCB
The Serial Number PCB’s main function is to identify the machine’s serial number. This PCB cannot be moved to
another machine.
Attempting to do so will generate an E355 and assistance from the Canon Reseller TechnicalError codes not listed in the Service Manual:
There are various error codes that are not listed in the Service Manual. Canon U.S.A., Inc. reserves the right to treat
these error codes as Proprietary Information. If you encounter any of the following error codes, contact your Canon

E245 E246 E247 E350 E354 E355
Note 4:
Please be advised that Canon U.S.A., Inc. treats the Counter Memory PCB and Serial Number PCB as “restricted” parts.
When a dealer orders these components they will be asked to provide the reason for their replacement, and the original
PCB will have to be returned to Canon U.S.A., Inc. for evaluation.
