Question about Brother MFC-5840CN All-In-One InkJet Printer

Print function stopped working. Brother MFC 5840CN

I downloaded an update for Print Shop Pro program. My Brother MFC 5840CN just stopped printing.

Brother MFC 5840CN will not print. I get the error message : Unable to Init. See Troubleshooting and routine maintenance chapters in User's Guide. I followed the instructions and got nowhere.

I uninstalled all MFC 5840CN software. I also downloaded uninstall Brother software and the full Brother MFC 5840CN software package.

I couldn't find anything on the Brother website about the printer function not working. A lot of information about setting up and using the FAX function.
I don't want to FAX. I just want to print and copy.

The paper feed works, the fax function dials a number, with sound.

The ink cartridges are in place, there's nothing stuck in the printer.

What's wrong with my MFC 5840CN? How do I fix it?

My brother 5840CN. lit says unable to print. the manual says to take the jam out - there was no jam. Turn it off, then on. i did that. It still says unable to print, look at troubleshooting page

errr.....No, no it does not. The Manual says that "unable to clean" means one of two things.....
1. The MFC has a mechanical problem.-OR-2. A foreign obstacle, such as a clip or ripped paper, is in the MFC.
but regardless, I don't believe it *IS* a 'cleaning' problem per se.Try resetting the power purge counter.

Press menu > Mono Start > 4x Arrow up after another. All lights will flash.
1. Power clean - Press 7>6>4 >Mono? Start.
2. Power Purge: 7>6 >3 >Mono Start.
Press 9>9 to exit maintenance mode. Run a print quality test print.

How to install LAN Brother MFC-5840CN on Windows 7 when original CD only has XP driver. Windows Update list specifies MFC-5840CN USB, but machine has option for LAN - is the driver the right one?

You cannot use the full driver and software package now. BUT:
Printing is possible, scanning and FAX is not possible at the moment. You download the Vista driver (x32 or x64) from the official Brother site and install it with the Printer Wizard in Windows 7.
