Startup problems with the Brother MFC-5840CD 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?

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.

Brother MFC-9420CN Paper Jam Error message w/ loud grinding noiz

please try this

  1. Turn off the printer.
  2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
  3. Also open the back cover of the printer if this model has one.
  4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
  5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
  6. If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
  7. If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
  8. Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
  9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
  10. see alternative if the problem is still not solved.

alternative :
Load a piece of thick paper, for example photo paper and press the resume button (may be diffrent button on diffrent models) a few times to the printer picks up the paper and puts it through the machine.

Squeaking and grinding upon printing.

MFC 240C turned on, and the LED indicates a print jam and a scraping sound, when there is no printer jam.

Makes loud sounds

I had the same problem with the loud grinding sound. The gears on the cartridge(s) is not turning but rather stripping creating a grinding sound. Reinstall all of the toner cartridges. If that doesn't work, pull each cartridge out and manually turn the gear on the cartridge. If the problem persists, you may need to purchase a new toner cartridge.

AF after cleaning cycles??????????????????????????

AF means that the scanner flatcable is not connected to the main pcb (When powering up you should hear a grinding sound from the scanner area). Open the scanner cover as for changing the ink carts. Open the small cover (looks like a " L ") and connect the white flat cable simply by pushing it into the main pcb.
