You still a problem. If you have visually verified that the fans are functioning with the unit on and the error message still comes up then it has to be a problem in the fan detection circuit, located on the actuator board. There is an ASC (Authorized Service Center) bulletin on this issue, #ASC20041116003 along with many other bulletins in the service manual. If you need the service manual email me privately and I'll send it you you. ([email protected]) The two fans you have in that unit are for the (1)DMD board and (2)Lamp. If you were to test anything I'd start by ESR testing the caps in the detection circuit. C525 and C565 would be my first guess, both are 100uf/25v. If you would rather skip the testing and just replace the board I believe the Samsung part number BP94-02149K and they cost around $60.00 plus shipping, but be VERY VERY VERY careful replacing this board for it is highly static sensitive. My best recommendation would be to have a service center come out and replace it... If the tech blows it, putting it in you're out nothing... Good Luck! Bill

We suggest you first attempt the basic/universal Canon ink level reset procedures before attempting any of the more advanced procedures provided on our Inkjet411 site*

A. Standard Ink Level Reset Procedure (printers without LCD display):
[ Refer to the 1st support video: http://inkjet411.com/?page_id=62 ]
1) At computer screen message, select 'Stop'/'Reset', 'OK', or 'Resume'.
....or....
2) Select 'Stop'/'Reset', 'OK' or the 'Resume' button (triangle-circle icon) on your printer for 5-8 seconds:
- Printing may continue under the 'ink out' condition.

B. Standard Ink Level Reset Procedure (printers with LCD display):
[ Refer to the 2nd support video: http://inkjet411.com/?page_id=62 ]
1) Install cartridge and start print job.
2) After first message appears, click 'OK' to continue. Printer should start printing.
3) If second message appears and printer's LCD screen displays error code "E", then DO NOT click 'CANCEL PRINTING'.
4) Press and hold down 'Stop'/'Reset' button (triangle-circle icon) on your printer for 5-8 seconds. Printer should start printing.

If you are able to produce a self test print, this is good since it illustrates that the cartridges are electrically stable...if you observe any 'E' or 'V' error states (i.e. E13 or V162 for example), this may indicate there is possibly an internal electrical problem with one of the ink cartridges. Refer to your user guide if E/V error messages are displayed.

*If, after following the suggested ink monitoring/level reset procedures, you still have an error condition which prohibits regular printing, then the ink cartridge probably has internal electrical damage (micro-electronics failure); such a failure is unrelated to the ink cartridge refilling process. Typically, when the cartridge fails the problem is 'masked' by the ink out/empty condition so it can be difficult to distinguish between the two. Many cartridges eventually do encounter problems or failures, especially after their original ink is gone and they are re-used, and this is often unrelated to the refill process (i.e. typically ~2 years from original manufacturing date). Refer to picture at bottom of this page: http://inkjet411.com/?page_id=1533

To verify the Canon printer is functional, install a brand new cartridge in it - this will 100% confirm whether your refilled, compatible or remanufactured ink cartridge is faulty or not.


For information on North American Canon ink refill services at a major retailer near you (should you wish to save ~50% on ink costs), general printing problem resolutions or advanced HP printer diagnosis procedures (advanced cartridge diagnostic tests/cartridge error bypass & printer reset methods, etc.), please visit Inkjet411: http://www.inkjet411.com

I got the 'lamp needs replacing' message. Ignored it. Now my tv screen is black when you try to turn it on and the blue button on the power button flashes?


You haven't replaced the lamp at time. Replace a new lamp along with its ballast and make a lamp time reset. If you wish to get more details about the lamp replacing procedure to Panasonic PTVs, check this link.

E:91:01 in DSC-W80


I can't recall all the Sony error codes off the top of my head, but I believe E:91 is that your flash is not working.

Can you take pictures at all or do you get just the error code? If you can take a picture with the flash off then your flash needs to be replaced.

If you can't use the camera you need to first press the reset button, then reset all camera settings to default.

1-3. PROCESS AFTER FIXING FLASH ERROR
When "FLASH error" (Self-diagnosis Code E : 91 : 01) occurs, to prevent any abnormal situation caused by high voltage, setting of the flash is changed automatically to disabling charge and flash setting. After fixing, this setting needs to be deactivated. Flash error code can be initialized by the operations on the HOME screen.

Method for Initializing the Flash Error Code
Initialize
Initializes the setting to the default setting. Even if you execute this function, the images stored in the internal memory are retained.
1 Select [Initialize] with v/V/b/B, then press z. The message "Initialize all settings" appears. 2 Select [OK] with v, then press z. The settings are reset to the default setting.

To cancel the resetting
Select [Cancel] in step 2, then press z.
· Make sure that the power is not disconnected during resetting.

Hope this helps.
