Startup problems with the MFC-5840CN All-in-one

When the MFC is plugged in and turned on, there is a grinding sound that comes from the area of the scanner bar. The led readout is" Please Wait..Res: Standard". The machine will cycle through this same process again and again, and never comes on for proper operation. The scanner bar, which usually aligns itself while the scanner is warming up, does not move and the rubber drive belt seems to be trying to drive the scanner bar forward, to no avail. The machine then turns itself off and tries the startup process again. An interesting observation - When the scanner bed and the printer cover is open to be able to look inside, the scanner bar aligns itself as normally the case, but the machine turns off immediately when the cover is placed in the down (normal - closed) position. I spoke with techs at the brother help site, but they were at a loss as to what is happening. Can anyone help?

Well thisone most techs have to see first. the simple solution is that the cover is binding some where and putting pressure on the scanner bar or its slide rail. my best sugestion is to take it to a printer tech and have them look at it

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.

Yes. There is some paper left in the very edge (mostly left hand side). Have a good look there by opening the scanner top.

Startup problems with the Brother MFC-5840CD All-in-one

You have to open the scannerbox very carefully. There is a contact on the lefthandside placed where the motor and belt is located. Check the position of the motor an ohter parts, by carefully sliding the scanner bar by hand. You may need to click in some parts because they have got loosen. Reassemble scannerbox.
