SOURCE: Printer doesnt come out of sleep mode (Brother MFC7420)

I'd be happy to give you the solution to this problem :)

You'll want to go into the menu and choose these options: 1,6, and 2. The final stop should give you the sleep menu.

The printer is setup for a default of 5 minutes. But you can change it from 00 to 99 minutes. To just shut it off, press the Options and Start button simultaneously and that will do the trick.

Here is the link to the manual: http://www.brother.ca/en/products/pdf/manuals/MFC7820N-UG.pdf

If I wasn't specific enough, the solution is on page 2-6

SOURCE: My Brother MFC 9440 CN Printer won't wake up once

Have you recently made any changes to your PC; upgraded any software? The problem could be your driver and you may want to get the latest one, but it sounds like the firmware needs to be updated. A repair facility would be able to take care of that for you.

SOURCE: My brother MFC7840w will not send faxes.

There are two jacks side-by-side. Be sure the phone line is plugged into the one marked LINE, not the EXT. jack, which is for extension phones or answering machines. OK, it's not that. Don't be mad - we had to check.
Most of the telephone circuitry is on the Main Board, but first the line is fed though a Network Control Unit, part number LG5857001. That NCU board is fairly cheap, but you don't know whether it's the problem until you replace it. NCU Board problems are often visible with a good magnifier: broken solder joints & stuff. Problems on the Main Board (part no. LT0226001) are more common and more expensive - maybe more expensive than replacing the machine.
Brother has a one-year warranty on these. If it's just past that, you might still be able to talk them into sending a Work Order to your nearest Brother servicer to do it free.

On a Desktop? Reboot, Open Control Panel, Power Options, set to High Performance, Advanced Power settings. Set Hibernate and Sleep to Never. Shut down your computer when not in use, it will last longer and a reboot everyday will reset the machine.

MFC_5840CN Will not print, not showing


Typically, a Brother machine stops printing, because the connection between the computer and the Brother machine is lost. There are multiple reasons for a lost connection.
  1. The Brother print driver is Offline.

  2. The Brother printer driver is not set as the default printer driver.

  3. The computer, not the monitor, connected to the Brother machine is set to go into sleep or standby mode. When the computer goes into sleep or standby mode, the connection between the computer and the Brother machine is lost and needs to be re-established.
Follow the steps below in order to re-establish the connection between the Brother machine and the computer:
  1. Verify that the Brother machine is connected with a USB cable and is not on a network.

  2. Verify the power cord and USB cable are securely connected. If the USB cable is loose on either end, disconnect and reconnect the cable securely. Test the machine by trying to print. If the machine does not print, go to STEP3.

  3. Cycle the power of the Brother machine by unplugging the power cord from power outlet, wait approximately one minute and plug back in. Once the Brother machine displays the date and time after plugging it back in, test the machine by trying to print. If the machine does not print, to Step 4.

  4. Reboot the computer connect to the Brother machine and then try to print again.

How do I get my brotherMFC-7220 printer off sleep mode


Turning it on and off should get it out of sleep mode, or just sending a print job to the printer should also wake it up. If that doesn't work you can try unplugging the printer from the power source for 40 seconds, then replug it in. If it is STILL stuck in sleep mode then something has failed on the printer itself.

Please make sure you rate my answer 4 thumbs up! Thanks so much for understanding, it would be a huge help to me. I would be forever grateful if you could do this for me. If you still have a question or concern about this problem please just respond / reply to my answer here before rating my answer.

Thanks
