brother printer/scanner cannot upload scanned document

it was working yesterday, now I have 2 Brother printers/scanner, different model that I try to scan and upload the scan on dropbox and it fail. Does dropbox have server down or any upgrades happen in last 24-48h???

And no, my space it not full (48%) and I can login into my account from computer.

I resolved this issue with my Brother MFC-L3710CW unit by logging into the machine and changing the TLS setting to 1.1/1.2. (192.168.... in web browser). It works with Dropbox Brother app now. It's always work for the MS OneDrive Brother app. You will need your units password to login to the administrator side of the Brother unit. Find it on the rear of the unit by the power cord input. Hope this helps!

Is this using a funciton that's built-in to the scanner? If so, you'll need to reach out to Brother for assistance. Brother would have created their own connection to Dropbox using the Dropbox API, and only Brother would be able to support that.

Try These Steps. May This Help You.

Wait a few minutes and check back.

Reopen the Dropbox app or refresh dropbox.com.

Make sure your Dropbox app is up to date.

Hi JC,
Just ran into the same issue. Did you solve it? How?
Thanks

Walter

Hey @hemzet, sorry to hear about this.

Could you share some additional information about the issue you're facing so that we can assist further?

hemzet

Hi @Walter,
Situation is actually the same as @borea_usinece described a year ago.

Suddenly, scan to web into Dropbox didn't work anymore. Connection Error 03 on the display as soon as the scan usually is uploaded to Dropbox. Multiple MFC printers in different networks have the same issue. No network or printer setting was changed.
On one device I created a new Dropbox connection resulted in the same error at the end.

I'm having the exact same issue. Discovered it first last night, an hour or so before @hemzet wrote his last message here. Connection Error 03 saving to Dropbox, no settings changed. Using a Brother DCP-9020CDW. Internet says it's because of proxy settings, but all other features works just fine, including printing via wifi.

Jay

Hi everyone, has there been any recent automatic updates to the service? Have you tried contacting Brother directly for support with their service?

hemzet

Hi @Jay
Haven't had the chance to speak to Brother support yet. Found this threat and thought maybe someone already has the answer... Will contact Brother after te weekend.

FVE

Same issue - Dropbox scan and printing stopped working sometime these last couple of days.

Error E03. Strangely enough I seem to be able to browse my Dropbox folders to find a file to print, but when selecting printing the error E03 occurs...:-(

Hannah

Hey @FVE, thanks for the nudge.

Are you using the same printer/scanner?

Can you send us a screenshot of the error please?

tomcrouze

I have the problem since yesterday (maybe that was earlier, but I did not have to scan anything). Maybe it's a server problem?

No problem with Google Drive.

hemzet

Brother support recommends to deinstall the Dropbox account and shortcut on the printer, then reregistering it. Haven't tried yet, will send an update later...

FVE

Hello @Hannah

I am using a Brother DCP-9020CDW

The error code I get is attached "Connection Error 03"

Many thanks for any kind of ideas you may have!!

Maybe this has to do with Dropbox increasing level of security for TLS?

Thanks in advance

Fredrik

Hannah

Has anyone tried the suggestion by Brother, that @hemzet mentioned, to see if that helps?

matkun

Hi!

I attempted Brother's suggestion now and removed everything Dropbox from my DCP-9020CDW, and set up the account again (also restarted the printer inbetween). Same result. I've also made sure that I had the latest printer firmware installed before trying this. There are no automatic updates performed on my printer.

I would also guess something server related as mentioned above (I have no facts to back it up with though, basing it on the similar issue when the printer's Scan-to-email stopped working since Office365 stopped supporting TLS 1.0 in favour of TLS 1.2 ^^; )

Tried setting up the printer to scan to my OneDrive account, and that seems to be working.

FVE

Hello @matkun,

Sadly I have the same experience - deinstalled everything related to Dropbox, upgraded firmware (latest from fall of 2019), rebooted printer. Disappointingly with same error.

Have checked OneDrive, which works fine.

Any help still appreciated!

hemzet

Brother support isn't helpful with this, which is very unfortunate.

Hi all, I hope you're having a smooth Wednesday so far!

It seems that what you're experiencing might be related to these updates that took place lately.

These changes would affect the compatibility, and hence possibly cause these issues.

I hope that shines some light.

hemzet

Thanks @Megan,

After many contacts with Brother support and hearing "it works for us" all the time, I finally received a message from Brother support that the issue could be reproduced and now is under investigation... Nothing we can do so far.

"We have tested the scan to Dropbox on a few different models. We can confirm there is currently an issue with the MFC-9330CDW and MFC-9340CDW, which our head office engineers will investigate."

Megan

Thank you for the update, @hemzet!

Provided you hear anything back from them, let me know in this thread too, so we can stay up to date on this.

If you have any news, or questions I am always one post away.

Hi guys, I have DCP 9020CDW model and I have exact the same issue with Error 3. I tried everything:

- Disabling firewall on my computer and router.

- Completely resetting the printer settings.

- Turning off and on the router and the printer

- Reinstalling the dropbox account

Nothing helps. Hope they solve the issue.

hemzet

Update from Brother support...

[..]Our engineers have advised that our server will be updated to resolve this issue, and currently it is estimated that it will be resolved next week. In the meantime, if you select Searchable PDF or Word as the file type, you may be able to scan now.[..]

hemzet

@Megan

I can confirm, changing setting to "Searchable PDF" works on an MFC-9330. Default PDF documents still cannot be uploaded which implies Brother is still working on this.
Out of curiosity, @Dude5050, did you try to switch to the alternative PDF setting on the DSC type?

FVE

Many thanks for the tip! Scanning "Searchable pdf" to Dropbox works fine also on my DCP-9020CDW.

Megan

Great job on the update and tips you're sharing @hemzet!

Thank you so much! 😊

I just received an email from Brother support that the issue with Dropbox uploads of scanned documents should be fixed. I verified the fix on my HL-3180CDW by successfully uploading a JPEG-format scan.
