Many thanks for this video ! My MFC-5320DW died after 3 years of medium use.. Botched a new supercap onto the board and it works fine again :)

[@amyjones25]

Thanks for the video. I would have struggled trying to get the printer open and find the supercapacitor without this video. I replaced mine today and now the printer turns on normal again.

[@BZZ86]

Nice mate - thanks. My in-laws printer died and this video saved me time looking for the problem.

[@LifeofWalk]

You are a genius!

[@alanefalcone3351]

Thank you!! The power reset worked for me! Nnot sure what happened but glad it's fixed!

[@davidmartnez2596]

Hola Terry Jones, gracias por compartir esta información, ya estaba cotizando otra impresora por que crei que ya había dejado de funcionar, saludos y gracias.

[@MrSalamDz]

Thank you bro . worked for me

[@tvsnath]

Thanks a lot for the Video, the hard reset solution also worked for MFC J5520DW

[@flobus9040]

Thank you, same issue @DCP-J4120DW

[@aacomm]

Hi, Same problem with brother MFC J4510DW. After Change SC still not power up what to do next😢😢😢

[@TerryJonesPrinterRepairs]

did you do the test?

[@cc-vk8hn]

thank you, I solved the problem. I greet you. Cosimo from sud Italy

[@_jandjdesigns]

Thank you!!

[@Bagummel1]

It works!!! Thank's a lot!

[@raydeath2813]

Would the same trick work for a Brother MFC-J470DW?

[@benjamind3448]

Also, is this called a supercapacitor in order to distinguish it from other types of capacitors?

[@bobiecheng1]

Thank you for the sharing, may I know where can buy this weak battery? Thanks again🙏🏻

[@TerryJonesPrinterRepairs]

It's in the description

[@brianbaker359]

Do you have a video if the power supply or control board has been fried? We had an electrical supply issue that resulted in 3 different electronic pieces destroyed by over voltage due to a faulty neutral wire.

[@benjamind3448]

How much is the capacitance on this Capacitor in micro farads.

[@TerryJonesPrinterRepairs]

You can buy the capacitor at this address for world wide shipping. www.fixitfastelectronics.com/printerparts.htm

[@ezzhammer]

@terryjonesprintingrepairs Hey mate, which direction does the super capacitor need to face? The one I bought off you doesn't have arrows, it's just got a small + and - on each side. Is it positive facing left of printer and negative facing right? Cheers

[@TerryJonesPrinterRepairs]

look at the shape and match the shape

[@ezzhammer]

@@TerryJonesPrinterRepairs Further explanation please. The shape that I have placed the new one is exactly the same as the one I've just pulled out. However, the new one has a + and - on either side of the super capacitor. Both sides look identical besides the + and -. I've placed the positive side + and soldered it to the left prong, and the - has been soldered to the right prong. I'm unsure if that's correct as it's not turning on and there was no + and - on the old capacitor, just an arrow at the top pointing to the right.

[@TerryJonesPrinterRepairs]

@@ezzhammer both sides are not identical.

[@alejandrovelascos.83]

ARE THE HEADS THE SAME FOR MFC J4620 DW OR J4510

[@santoskadiro447]

My brother MFC-J480DW panel button doesn't work any idea please help

[@martin54123]

I have a Brother mfc j53200dw printer vurtually the same as this but can't get the cover levered up to access the Super capacitor, tried everything, I have removed all screws identified and nothing else in the way, can't see any hidden screws but the back of the cover refuses to budge even by lifting a little with spud device. Does my model differ????

[@TerryJonesPrinterRepairs]

this model is difficult to work on due to the extra feeder at the back which I have never been able to work out how to remove, I did one yesterday by using blocks of wood to hold the inner cover up just enough to disconnect the flat flexible cables and get a soldering iron in there.

[@martin54123]

@@TerryJonesPrinterRepairs Finally managed to lift it enough to remoce super cap' as the cover is normally hidden I might even cut a very neat square hole to solder from above, almost as though they don't want you to work on their printers!

[@TerryJonesPrinterRepairs]

@@martin54123 Its just this model with the feeder on the back that makes it difficult. I've yet to find some spare time to work out how to pull it off but i'm sure it is actually really easy once the trick is worked out. In the meantime i just use blocks of jenga to hold it up, disconnect the cables, cut the old cap off the board then solder the new one on. Give the printer body a cleanout 15-20 minutes tops and easy $180.00 income. Do it 4 times a day and life is good.

No power, would not turn on HL5450.... please share your thoughts on this matter

[@TerryJonesPrinterRepairs]

[@marijanmarijan1073]

ich habe den drucker immer mit den trick angemacht und dan ist er nach 6 monaten ganz ausgegangen,dan tauschte ich den kondensator und es ging immer noch nicht, dan fand ich das die sicherung im netzteil ausgefallen ist ,nach den tausch ist die wider durchgebrant ,was ist da an den netzteil defekt gruß aus deutschland I always turned on the printer using the trick and then after 6 months it went out completely, then I replaced the capacitor and it still didn't work, then I found that the fuse in the power supply had failed, after the replacement it burned out again, What is wrong with the power supply? greetings from Germany

[@TerryJonesPrinterRepairs]

@@marijanmarijan1073 as explained in the video you have let it go too long. The first sign that the capacitor is starting to leak is the fact that you cannot turn it on properly simply by pushing the power button. If you had replaced the supercapacitor when your printer first started developing this problem you wouldn't be in the position you're currently in. The failed leaking supercapacitor has damaged the motherboard and in turn that is then damaged your power supply. Your lack of attention to the problem means you now need to get a new printer or find someone who can supply you a power supply and a main board.

[@marijanmarijan1073]

@@TerryJonesPrinterRepairs thanks die antwort ist nicht gut aber jetzt weiss ich das ich neuen kaufe viellen dank ,sie sind sehr nett

[@timvancouillie2879]

I've tried but It didn't work for me 😪

[@TerryJonesPrinterRepairs]

All Brother printers of this vintage need to be regreased with fluorinated silicone oil otherwise the motors draw too much current from the extra friction created by the dried up grease causing the power board to blow up.
