I am having the same problem my mfc-j6520dw printer only when I hold down the on button and plug in the power cable the white house light comes on and then goes out after a minute. Previously the screen would come on and ask for the paper tray to be replaced but this does not happen now. Has anybody else had this and how have you fixed it. Thank you.

Worked for me on the second try. When you unplug the printer, make sure you wait a solid minute before plugging it back in and hold the power button for a good 10 seconds before you plug it in. Obviously continue to hold the power button for a minute once plugged in. 2 minutes total.

Hello Richard

WOW! It worked for my old brother printer MFC-L2740DW . I did exactly what you described the steps above - unplugged the printer from the wall plug - then waited one minute. Then I held the power button for 10 seconds before I plugged back the power cord into the wall plug. Then continued to hold it for a minute and it turned on right away.

I also checked my wall plug to make sure that it was working with another appliance. Thanks so much for your help!

I followed Richard Tufo and it worked. None of the other instructions worked. This is definitely a design fault. The process is as follow:

1- Unplug AC and keep it unplugged for 1 minute

2- Press power button (Without plugging it in) and leave it pressed

3- 10 seconds later plug AC

4- Home light will come on, then full screen. Release power button

It should work now.

Hi,

Try the following:

1. Unplug the power cord from the printer.

2. Remove the paper tray.

3. Press and hold the Power button.

4. While still holding the Power button plug in the power cord

5. Wait for it to start, when normal home screen displayed release the power button.

6. There should be a message to replace the tray.

Hopefully it will be good to go.

Update Try it 2 or 3 times before you give up. According to the comments below, for some it did work but only on the second or third attempt.

Update #2 According to some comments below the above procedure was also successful when used on other Brother printers, laser as well as inkjet models.

Also if it does succeed here is a link which allows you to download the "Firmware Update Tool" which checks to see if there are any firmware updates for your printer. Brother doesn't say if there are or not but it never hurts to check in case they have a 'fix' available. Scroll down to Firmware.

Doesn't turn on after standby.

This seems to be a common problem on many printers of this series, but the solutions presented here are just a workaround. You have to go and unplug your printer each time you want to use it. Quite silly for a WiFi printer...

I've dug a bit deeper; the problem lies in a supercapacitor 5,5V 0,22F on the main pcb motherboard. It's unable to keep a charge and therefore the printer fails to come out of standby.

You can get to the pcb by removing 9 screws, unplugging a few connectors and a bit of fiddling. Go in from the top, remove the scannerbed and work your way down. The supercap itself is a throughhole part that's easily replaceable with a standard soldering iron and costs around €2.

Good luck fixing this chinese piece of $@$* and getting your money's worth out of it!!

We also have the problem where the printer occasionally won't turn on. Jayeff's solution worked once, and sometimes just unplugging and plugging in again works. However, today the printer would not turn on, so we plugged it into our APC Line-R 600 voltage regulator and the printer started fine. We found out two years ago that the voltage coming into our house was on the high side of normal most of the time, and our computer would exhibit functional problems. APC Line-R 600 is less than $50 at Walmart, Office Depot, and Amazon. The electric company, here anyway, will check your line voltage for free.

I also had the problem where my hl l2380dw would not power on occasionally (same socket).

Sometimes switching socket would work, sometimes not. Maybe it was more about unplugging it for a longer time?

In any case, ran into this issue again, saw this post, pulled out the tray (not sure if this is important or not) unplugged for about 30 seconds (a little longer than I had tried previously), and then while pressing the power button re-plugged it in... it powered on immediately.

Strange.

My Kyocera FS-3820N will not power up, anyone has a fix for this problem? I plugged it up once and it came on, this I unplugged it without powering down. Now it will not come on at all.

I used the prior method and last time it did not turn on, until I left it unplugged for over 1 minute before trying it again, and it worked. Very important that the internal electronics are completely off.

You can also try another method to overcome your problem. The following method is taken from Brother MFC-J4510DW Manualand i hope this will help you more effectively.

Keep holding power button while plugging power cord back in and for another 60 seconds after, then release it. Make sure that there should not any damage or crack in printer wire. The proper voltage rate must be passed. The lithium battery inside printer should be recharged. If simple restart will not fix your issue, then move to hard reset.

I had this problem and the paper tray solution did not work. With having to get work done immediately I was in a bind. I then opened the ink cartridge cover, popped out, and replaced a cartridge. I then held the on button, plugged it in, and it was working. Very relieved.

this did the trick for me popping out the cartridge as you instructed, seems so silly.
