Just got a new computer w/windows 7 and now my brother mfc-8840D won't scan to pdf now? Any ideas on a solution to fix?

How to get a MFC-8840/D/DN to scan to Windows 7 over the network or by USB:

First - Download the Windows Vista Full Driver & Software Package from Brother: Brother MFC-8840DN driver download page

Install the drivers using a custom install - pick only the Network scanning drivers, unless you want the other junk - no promises on how well the other stuff works.
Alternatively, if connecting the MFC-8840DN to Windows 7 by USB, download the Printer and Scanner Driver for Local Connection. It is a separate download. Install only the Scanner driver.

Once the Vista scanner driver is installed, you can test by running the built-in Windows 7 Scanner Wizard. Here are instructions on how to test.

As far as conversion to PDF, that will depend on the software. I am not sure if the Control Center or Paperport softwares work on Windows 7. I have not tried those. I have found that freeware STP will works fine.
Here is a link to the STP homepage.

you take the toner and drum assembly out of the printer, set it on a level surface, press the blue lever on the left side rear, and lift and remove the toner. Remove any packing material from the new cartridge, set the front toward the drum in first and lower the rear down until the blue lever clicks. Re-install the assembly into the printer...good to go!

How to replace Hinge assembly of Automatic Document Feeder

You can try to get a hinge @ a local authorized brother dealer. I just got mine for 20 bucks, I think that the guy ripped me off, but I needed. Once you get it, it is very easy to replace. 1St, replace the old one by removing the screw in the back of the hinge (back of printer). then pretend that you are lifting the whole automatic feeder up. At this point you will see the right hinge looks likeit it coming out. Don't pull it out completely. Just pull it enough that you can flip the feeder enought so you can uncrew the 3 screw attached to the feeder. Once you remove the broken part, install the new hinge. make sure that you screw hinge first before you slip it down to the bottom hole then screw the hinge to prevent it from moving.
PS: try not to flip the feeder too far back
good luck
