Ether the paper sensing lever is broken or there is dust accumulation or paper fragments inside the optical sensor.

You probably printed a document that was forced to the manual feed. Place some paper there and it should print. Go to your printer preferences and set the default tray to tray1 instead of Auto.

If you are looking for the driver disk information, you could try the following Brother site: http://welcome.solutions.brother.com/bsc/public/us/us/en/dlf/download_top.html?reg=us&c=us&lang=en&prod=hl5240_all
You should be able to download it from there.

It may some paper jam inside your printer . open the front cover pull out the cartridge and look any jammed paper is there or not. if not the the problem may came from your toner drum.

Hello sir; when you put the new toner in did you remove the seal tape ?

that error usually indicates that the toner has reached its end of life
or the drum is not properly installed.

i had one person who put the toner in but threw the drum cartridge away.

my printrr is a 3240c. It will not let me download the disk, that I have.

you need to replace drum cartridge, when you buy one back ,look new one then you'll find out where is the drum.

I just solved my similar problem- switch off printer, open front door, hold down go (blue) button. Now switch on, holding the go button for about 10 seconds then closing the door.This left the lights all off, green light only when pressing go. Switch off then on, it worked! hopefully this helps someone else. Ross
