It’s a common scenario: your printer’s power light is on, everything looks fine, but when you send a document, nothing happens. Your computer might even say the printer is “offline” or “not responding.” Often, the culprit isn’t a major error, but rather your printer settling into a deep sleep or power-save mode that Windows isn’t effectively waking it from.
This guide will help you understand printer sleep modes and provide step-by-step instructions to troubleshoot situations where your printer is powered on but unresponsive. We’ll show you how to attempt to wake your printer up and adjust settings to help ensure it’s ready when you need it.

Understanding Printer Sleep and Power Save Modes
Modern printers are designed to be energy-efficient. To reduce power consumption, they often enter various power-saving states:
- Sleep Mode: The most common state, where the printer uses minimal power but is designed to quickly wake up when a print job is sent.
- Deep Sleep Mode: A more aggressive power-saving state where the printer consumes even less power but may take longer, or require a physical interaction, to wake up.
- Auto Off: Some printers can be set to completely power off after a period of inactivity.
While these modes save energy, sometimes the communication signal from your computer isn’t sufficient to “wake” the printer, making it seem unresponsive or offline.
Signs of Sleep Mode Related Issues:
- Printer power light is on, but it doesn’t respond to print commands.
- Printer appears “offline” on your computer, but physically it’s powered on.
- Print jobs get stuck in the print queue.
- The printer wakes up if you press a button on its panel, but not from the computer.
Step 1: Simple Wake-Up Attempts
Always start with these quick methods.
- Press Any Button: Simply press any button on your printer’s control panel. This often wakes it from a lighter sleep mode.
- Power Cycle the Printer:
- Turn the printer OFF using its power button.
- Unplug the printer’s power cable from the wall outlet.
- Wait 30 seconds.
- Plug the power cable back in and turn the printer ON. This performs a hard reset and forces it to fully wake up.
- Restart Your Computer: A full system restart can sometimes refresh communication.
Step 2: Adjust Printer Sleep/Power Save Settings (On the Printer)
Many printers allow you to adjust the sleep timer or disable deep sleep modes through their own internal settings.
- Access Printer Settings: On your printer’s control panel (LCD screen), navigate to the “Setup,” “Energy Save,” “Power Management,” or “System Settings” menu.
- Locate Sleep Timer/Auto Off: Look for options related to “Sleep Timer,” “Auto Off,” “Power Save Mode,” or “Idle Timer.”
- Adjust Settings:
- You can try extending the sleep timer (e.g., from 5 minutes to 30 minutes or 1 hour).
- If available, you might find an option to disable deep sleep or auto-off entirely. (Be aware this will likely increase power consumption).
- Consult Your Printer Manual: The exact names and locations of these settings vary significantly by printer brand and model. Refer to your printer’s user manual or the manufacturer’s official support website for specific instructions.
Step 3: Check Power Management Settings in Windows (For USB Printers)
For USB-connected printers, your computer’s power management settings can sometimes affect how it communicates with the printer.
- Open Device Manager: Right-click on the Start Button and select “Device Manager.”
- Locate USB Root Hubs: Expand the “Universal Serial Bus controllers” section.
- Check Power Management:
- Double-click on each “USB Root Hub” entry.
- Go to the “Power Management” tab.
- Uncheck the box that says “Allow the computer to turn off this device to save power.”
- Click “OK” for each USB Root Hub.
- Restart Computer: Restart your computer for these changes to take effect.
Step 4: Ensure Printer Drivers Are Up-to-Date
Outdated printer drivers can sometimes have issues with managing power states or waking the printer.
- Update Drivers via Windows Update:
- Go to Start Menu > Settings > Windows Update.
- Click “Check for updates,” then look under “Advanced options” or “View optional updates” for “Driver updates.” Install any listed printer drivers.
- Reinstall Driver from Manufacturer: For the most reliable and latest driver that might improve power management, download and reinstall the full software package from your printer manufacturer’s official website.

Conclusion
A printer that’s “on but not printing” often points to its power-saving modes. By performing simple wake-up attempts, adjusting the printer’s internal sleep settings, and ensuring your drivers are current, you can significantly improve its responsiveness. Understanding these power management features empowers you to help keep your printer ready for action whenever you need it.
