Mfc-9970 cdw doesnt turn on after power surge

The machine doesn't power on after a power outage. I believe there was a power surge, because several surge protectors needed to be replaced. Can this be fixed or do I need to replace it?

SOURCE: how to replace print heads on brother mfc

The printhead for this brother model is a service replacement, all the covers come off and the ink tubes and encoder strip. After replacement many settings have to be set in service mode, not a job you can do at home, plus the printhead costs nearly $100.00.

SOURCE: Brother MFC-465CN printer. Need a fix for error 46.

The problem is due to the fact that Brother machines excessively self-clean. Each time they self-clean a small amount of ink is dumped in to a holding tank/sponge. When a predefined number of self-clean operations have been performed, the machine refuses to print and gives the error message you have stated. Brother state that the tank/sponge must be replaced before the counter is reset, again by a Brother agent.

However, there is a way of reseting the self-clean counter yourself - if you Google your model number and the error code somewhere in the results you'll find how to do it. The only risk of doing this without changing the tank/sponge is that it will eventually overflow and leak out the bottom, but I did my Brother all in one some time ago and have had no problems yet.

SOURCE: How do I reset the

On the TN-155 toner cartridge, a mechanical 'flag gear' that will reset the counter for each individual cartridge when first 'triggered'.
After each page print, the appropriate counters are incremented regardless of toner content (that is why it is still printing 'flawlessly') and after a pre-determined count has been reached, you will get a warning to change the drum as is will then be notionally (not actually) empty.
Before you decide to reset the 'flag gear' on the drum, make sure you are not actually nearing the physical empty state ... it might be a wiser decision to purchase a refill kit which should come with instruction on how to fill and reset the 'flag gear' (this needs some dismantling of the drum cartridge) or buy a compatible or genuine toner drum cartridge.
In any case, Google 'Brother drum flag gear' for more information.
Good luck!

Powersurge.When i turn tv on,clicking sound and would not turn on.Replaced main board.Now it turns on, but is blackscreen and you cant poweroff unless you unplugit.replaced main powersuppy,no change

no, if you have had a power surge then several, if not all, the components may be fried/blown. probably best to take all the bits and give them to a tech to see if a tv can be pieced together.
You should, whether the tv is salvageabl
or not, get, buy the best surge protector you can.
I recommended, elsewher on this website, that everybody should acquire surge protection for their electronic devices.I read countless queries that say "we had a power outage and now such and such no longer works"....yes , because the power outage was a surge that probably blew up electronic devices for several blocks around where you l9ive.
old , uncared for, unserviced infrastructure is costing members of the public a fortune.

Emerson 2.8 Cu. Ft. doesn't automatically turn on after power outage

Check breaker. Was there a surge of electricity when the power went out. This may be a simple fix. Sounds like the breaker is tripped. Test the outlet with a light to see that power is to it.

Hi,first you need to check if fuse has not been blown out.Because when POWER comes back after an outage there is a surge voltage flowing through electrical lines.It is advisable that when their is a POWER outage you have to turn off your FUSE box or SAFETY box to make sure that it won'tdamage appliances when POWER comes back>Technically when POWER SOURCE or SUPPLY has been shut off for a period of time.When POWER is back, expectantly there is an abnormal flow of current/line; current will not be as stable until a period of time..AC current behaves like a wave,values changes from time to time especially when POWER SOURCE has just been TURNED ON..So better turn off FUSE BOX when experiencing POWER OUTAGE so that when power comes back SURGE VOLTAGE wont flow within the circuit>Hope this helps..

I have a MFC -6490 CW copier. After a power outage in teh building the on swithch no longer turmns the copier on. Is there a internal surge protection on this machine?

There is no internal surge protector on this unit.
Unplug the power cable and plug it back directly into a different power source.

If it still doesn't turn on then the power source is fried.
The MFC-6490CW has a 2 year warranty so as long as you have your proof of purchase you can get it repaired or replaced within warranty.
Your machine is definately still under warranty because this model has not been on the market for 2 years.

Won't turn on

Best suggestion I can tell you is try unplugging your Wii for 2 minutes. Then plug it back in, and try again. I know it sounds weird, but I've done it for a few things after power outages/surges.
If that doesn't work, contact Nintendo.
