Will not initialize

I have recently bought the brother mfc 420 all in one. I installed the drivers, did all the proper installations but the printer keeps coming up with an error message saying that it is unable to initialize. Can someone help me with this problem?

Take it back to the dealer! Better do not fix that problem by opening the printer! If it is a second hand printer, write again here.

How do I download a cd for installation of my MFC 420 brother printer when yours get lost?

You can download the drivers, etc. that you need from here:


Printer installation problem

Check brother's web site and see if you can locate the "uninstaller".

This should wipe the old install attempts. Unplug the unit. Down-load the latest Vista driver from the brother website. Follow the install instructions for your driver, they should be printed in the browser.
Plug the unit in when instructed to do so.
I hope that helps. The uninstaller can work wonders sometimes, but it doesn't always help.
