Adjust the Sleep Mode setting
Adjusting the Sleep Mode setting on your Brother printer can help you avoid the issue of the printer not waking up from sleep mode. Here are the steps you can take:
Firstly, it's important to understand what Sleep Mode does. Sleep Mode reduces power consumption by turning off the fuser inside the printer when it is idle. You can choose how long the printer remains idle before it goes into Sleep Mode. The default setting is 5 minutes, but you can adjust this to your preference.
To adjust the Sleep Mode setting, follow these steps:
- Press the "Start" and "Options" keys simultaneously.
- The LCD screen will display "Sleep Mode: On".
- Use the Up or Down arrow key to select "Off".
- Press the "OK" key to confirm the change.
- Press the "Stop/Exit" key to exit the menu.
By following these steps, you can turn off Sleep Mode and prevent the printer from automatically entering a low-power state after a period of inactivity. This should help resolve issues with the printer not waking up from sleep.
If you continue to experience problems with your Brother printer not waking up from sleep mode, there are a few additional troubleshooting steps you can try. These include turning the printer off and on again, opening and closing the front cover, or sending a print job from a different device.

Turn the printer off and on
If your Brother printer is in deep sleep mode, one way to wake it is to turn the printer off and then on again. This method is confirmed by multiple users to work.
Firstly, locate the power button on your Brother printer. This is usually a circular button that you push in to turn off, located on the front or top of the printer. Once you have located it, simply press the button to turn the printer off. If you are unable to find the power button, refer to your printer's manual or search for your specific model online.
After turning off the printer, wait a few moments for it to power down completely. You will know it is off when the display panel turns off or goes blank, and any lights or indicators turn off. If your printer model has a physical switch, ensure that it is flipped to the "off" position.
Now that the printer is off, you can turn it back on. Simply press the power button again, and hold it down until the printer powers on. You may need to hold the button for a few seconds. The display panel will turn on, and the printer will begin its startup process.
Once the printer has finished starting up, it should be awake and ready for use. You can try sending a test print job to ensure it is no longer in deep sleep mode. If you continue to experience issues with deep sleep mode, there are other methods to wake your Brother printer that you can try.

Open and close the front cover
If your Brother printer is in deep sleep mode, one way to wake it up is by opening and closing the front cover. This method works for the Brother HL-L2305W printer model.
To do this, first, locate the front cover of the printer. This is usually the side of the printer where the toner cartridge is installed. Next, gently open the front cover by pulling it towards you or by pressing the release button or lever, depending on your printer model. Once it's open, you can close it by gently pushing the cover back into place until you hear a soft click or until it latches securely.
Opening and closing the front cover of your Brother printer can help bring it out of sleep mode and deep sleep mode. It's a simple process that only requires you to manipulate the front cover of your printer. Remember to handle the cover with care and ensure it is securely closed before attempting to use the printer again.
By performing this action, you are essentially resetting the printer's current state and prompting it to become active again. This method is particularly useful when the printer is unresponsive to other wake-up methods, such as pressing buttons or sending print jobs.
