How to wake a printer from sleep mode
Sleep mode is a common feature on printers that helps conserve energy when the device is not in use. However, sometimes printers may not wake up from sleep mode, causing frustration and inconvenience. Here are some detailed instructions on how to wake a printer from sleep mode and prevent it from happening again:
Waking the Printer:
- Press a control panel key: Try pressing any key on the printer's control panel to wake it up. This is usually effective for printers that are not in deep sleep mode.
- Power cycle the printer: If the printer doesn't respond to key presses, try power cycling it. Unplug the power cord, wait for about 30 seconds, and then plug it back in. This method can be effective, but it may be inconvenient to access the power outlet frequently.
- Press the power button: For some printers, simply pressing the power button may wake the device.
Preventing Sleep Mode Issues:
- Adjust sleep mode settings: Check your printer's settings to adjust the sleep mode duration or disable it. On the printer, navigate to the menu, choose "General Setup," then "Ecology," and adjust the "Sleep Time." While some printers don't allow disabling sleep mode, you can usually extend the duration before it activates.
- Update firmware: Outdated firmware may cause sleep mode issues. Check with the manufacturer for known bugs and update to the latest firmware version if necessary.
- Reinstall software: If issues persist, try reinstalling the printer software or driver. This can help resolve any software-related problems that may be causing the printer to remain in sleep mode.
- Check connectivity: Ensure that your printer is properly connected to your computer or network. Issues with connectivity may trigger sleep mode or prevent the printer from receiving wake-up signals.
By following these steps, you can effectively wake your printer from sleep mode and prevent future occurrences of this issue.

Adjusting sleep mode settings
Sleep mode is a useful feature on your printer that helps conserve energy. However, it can be frustrating if your printer goes into sleep mode too frequently. The sleep mode timer is automatically reset when the printer receives PC data or makes a copy. The factory setting for this is usually 5 minutes, but this can vary depending on your printer model and settings.
If you want to adjust your printer's sleep mode settings, there are a few things you can try. Firstly, check if your printer has sleep mode enabled by going to the Control Panel, then Devices and Printers. Right-click on the printer and select Printer Preferences to look for an option to disable sleep mode or adjust the sleep timer. You can also right-click on the printer, select Printer Properties, and look for similar functions. Refer to your printer's manual or the manufacturer's support services if you need further assistance.
If you're using a Windows PC, you can also adjust power settings by going to the Control Panel, selecting Power Options, and then changing the plan settings for your selected power plan. You can also change the advanced power settings. If you're using a 32-bit version of Windows, you can set the Auto Power-Off Time Setting to 0 minutes. However, if you're using a 64-bit version, you'll need to connect your printer to a PC with 32-bit Windows or a Mac to reprogram certain printer models.
For some printers, you can adjust the sleep mode settings directly on the printer. For example, on some printer models, you can press the Menu button, navigate to General Setup using the arrow keys, select Ecology, choose Sleep Time, and then adjust the sleep timer using the touch screen. Unfortunately, some printers do not allow you to disable sleep mode entirely, but you can usually extend the sleep timer to a longer duration.
If you're experiencing issues with your printer not printing after entering deep sleep mode, there are some troubleshooting steps you can try. These include updating the firmware on your printer and wireless router, reinstalling the printer software, and checking your network connectivity settings.

Troubleshooting a printer that won't wake from sleep mode
Sleep mode is a common feature on printers that helps to conserve energy when the device is not in use. However, sometimes printers may not wake up from sleep mode, causing frustration and inconvenience. Here are some troubleshooting steps to try if your printer won't wake up:
- Check Power Connections: Start by checking the power connections to your printer. Ensure that the power cord is securely connected to both the printer and the power outlet. Try unplugging the printer, waiting for a few seconds, and then plugging it back in. This power cycle can sometimes reset the printer and wake it from sleep mode.
- Adjust Sleep Mode Settings: Check your printer's settings to see if you can adjust or disable sleep mode. On some printers, you can extend the sleep time or set it to a longer duration before the printer automatically enters sleep mode. Look for these options in the printer's menu or preferences.
- Press a Control Panel Key: If your printer has a control panel or touchscreen, try pressing any button or key to wake the printer. Sometimes, simply interacting with the printer's interface can bring it out of sleep mode.
- Restart the Router: If your printer is connected to a wireless network, try restarting your router. Power cycle the router by unplugging it, waiting for a few seconds, and then plugging it back in. This can help refresh the network connection and potentially wake the printer.
- Check Network Compatibility: In some cases, network-enabled printers may not be compatible with certain network environments. Try connecting the printer directly to a computer via USB to see if it wakes up. If it does, the issue may be related to network compatibility, and you may need to work with your network administrator to isolate the problem.
- Update Firmware: Outdated firmware can sometimes cause issues with sleep mode. Check with the printer manufacturer to see if there is an updated firmware version available for your model. Updating the firmware may resolve any bugs or compatibility issues that are preventing the printer from waking up.
- Contact Manufacturer Support: If none of the above steps work, it is advisable to contact the printer manufacturer's technical support team. They may have specific recommendations or solutions for your particular printer model. They can also guide you through more advanced troubleshooting steps or recommend repair options if necessary.
Remember to keep your printer's firmware and drivers up to date, as this can help prevent sleep mode issues and ensure the smooth operation of your printer.

Printer goes to sleep and misses the interrupt to print
If your printer goes to sleep and misses the interrupt to print, there are several steps you can take to resolve the issue. Firstly, check if your printer is connected to a power strip or surge protector. If so, try power resetting your printer by unplugging it for 1-2 minutes and then plugging it back in. Additionally, ensure that your printer's firmware is up to date, as outdated firmware can cause network connectivity issues that may interfere with printing.
You can also adjust your printer's sleep settings to prevent it from going to sleep too quickly. Check your printer's manual for instructions on how to access and modify the sleep settings. Usually, you can extend the sleep timer up to 90 minutes or disable sleep mode entirely. If you cannot find the option to disable sleep mode, try going into the "Ecology" or "Sleep Time" settings and turning it off using the up and down arrows.
If your printer is connected to a Windows computer, you can update your printer settings to ensure it stays online. Go to Control Panel > Devices and Printers. Right-click on your printer and select "Printer Preferences" or "Printer Properties." Look for an option to disable sleep or timeout mode and make sure that the System Mode Timeout is set to zero. You may need to refer to your printer's manual or the manufacturer's support desk for detailed instructions.
In some cases, you may need to reinstall the printer software or driver to resolve deep sleep issues. If your printer is a Brother machine, you can follow the steps provided on the Brother website to uninstall the software and reinstall the MFL-Pro Suite using the "Full Driver and Software Package." After reinstallation, attempt to print a document or test page to verify that your printer is working correctly.
If your printer still misses the interrupt to print, try power cycling your printer and router. Power off both devices, wait a few minutes, and then power on the router first, followed by the printer. Check if your printer connects to the router and attempt to print again.
