Printer won't wake from sleep mode: how to keep it reachable

A printer that won’t wake from sleep is one of the most common reasons a printer shows as offline. You send a job, nothing happens, and it only prints after someone presses a button on the printer. Sleep itself is not the fault. A printer in sleep mode is designed to wake up the moment a job arrives. If it does not, the job is not getting to it, or the printer is not asleep but switched off. This guide fixes both.

For a printer that shows offline at any time, not only after sleeping, start with printer offline fix. If it keeps dropping off Wi-Fi while awake, see printer keeps disconnecting from Wi-Fi.

Step 1: Sleep or auto-off?

Printers have two different power-saving settings, and they behave very differently:

• Sleep (or power save, energy saver, low power mode): the printer dims its display and stops most parts but stays on the network. A job should wake it.
• Auto-off (or auto power off, power off timer, shutdown timer): the printer switches itself completely off after a set time without use. It cannot receive jobs until someone presses the power button.

If the printer’s power light is off and the display is dark, and nothing wakes it except the power button, auto-off is probably on.

1. On the printer’s control panel, open Settings, Setup, Power, Eco or Energy settings.
2. Find Auto-off, Power off timer or similar.
3. Set it to Off or Never, or choose a longer time, if you need to print remotely at any time.

On some printers auto-off only applies when nothing is connected, so a network connection keeps them on. Others turn off regardless. Your user guide explains your model’s behaviour.

Step 2: Give the printer a fixed network address

This is the fix that solves most “offline after sleep” problems. Routers hand out IP addresses to devices for a limited time. A printer that sleeps for a long time may come back with a different address, while the computer still sends jobs to the old one.

Option A: reserve the address in the router (recommended).

1. Print the printer’s network configuration page from its menu and note its IP address and MAC address.
2. Sign in to your router’s settings and find DHCP reservation, address reservation or static lease.
3. Reserve the current IP address for the printer’s MAC address.

Option B: set a static address on the printer. In the printer’s network settings, set the IP address manually, choosing an address outside the range the router hands out, with the same subnet mask, gateway and DNS as your network. Only do this if you know your network’s settings; a wrong value disconnects the printer.

Then check the computer is using that address (Step 3).

Step 3: Check the port on the computer

In Windows 11:

1. Open Settings > Bluetooth & devices > Printers & scanners, select the printer and choose Printer properties.
2. On the Ports tab, find the ticked port.
3. If it is a Standard TCP/IP port, choose Configure Port and check the address matches the printer’s current IP address.
4. A WSD port finds the printer by discovery and usually follows address changes, but discovery can fail after sleep on some networks. If WSD keeps losing the printer, adding a TCP/IP port with the fixed address is more reliable.

On a Mac, remove the printer and add it again using IP in the Add Printer window with the fixed address, if the Bonjour connection keeps losing it.

Step 4: Improve the Wi-Fi connection

When a printer dozes, its Wi-Fi radio may go into a low power state. A weak or busy connection can then drop completely.

• Move it closer to the router or a mesh point, or connect it with a network cable to test.
• Check the band. Many printers only support 2.4 GHz. Routers that combine 2.4 GHz and 5 GHz under one name can confuse some printers when they wake. If your router allows it, give the 2.4 GHz band its own name and connect the printer to that.
• Update the printer firmware. Makers sometimes fix wake and network issues in firmware; use the update option in the printer menu or the maker’s app.

Step 5: USB printers that vanish after sleep

When a USB printer does not respond after it or the computer has slept:

• Plug it straight into the computer, not into an unpowered hub or monitor port.
• Try a different USB port.
• In Device Manager, open the USB root hub or the printer’s USB entry, and on the Power Management tab, clear Allow the computer to turn off this device to save power.
• In the power plan’s advanced settings, the USB selective suspend option can also be turned off on many PCs.

USB printer not recognized covers the rest of the USB checks.

Step 6: Clear a queue that built up while it slept

If jobs piled up while the printer could not be reached, the queue may be stuck even after the printer wakes. Cancel the waiting jobs, then print again. If they will not cancel, see print spooler error fix. If Windows shows the printer as paused, see printer paused in Windows 11.

Quick checklist

• Auto-off switched off or lengthened; sleep left on.
• Fixed IP address by router reservation or static setting.
• Computer port pointing to that address.
• Strong Wi-Fi or a cable; 2.4 GHz band if the printer needs it.
• USB direct to the PC, power management off for the port.
• Old jobs cleared from the queue.
