Samsung Network Printer Won't Wake

Yesterday I installed a new CLP-415NW printer for a client. Install was easy and the client loved the print quality. But we ran into one snag....

When the printer went to sleep after 5 minutes (default setting) it wouldn't automatically wake up when you sent a print job. The printer appeared offline and you needed to physically press a button on the printer to wake it up. When it was asleep, you couldn't print to it, you couldn't access the web interface, and you couldn't even ping it.

I figured this was crazy that there has to be an easy solution for it. So, I started looking at settings on the printer and nothing seemed to fit. I tinkered with when sleep occurred, but had no success.

I emailed Samsung support and they provided the following link, which described how to disable bidirectional support in the network port. This had no effect.
Then today I spent a frustrating hour and a half on a web chat with Samsung support. I got the following suggestions, of which none of them fixed anything:
  • Change to a static IP address. I had a DHCP reservation so, this had no effect. However, offline printers can occur when the printer changes IP. So, at least this was relevant.
  • Install a new version of the Samsung  SyncThru software on my PC. This software wasn't in use.
  • Set the sleep timeout to maximum value. This was the final bit where the tech support guy gave up and basically said it would need to print every 60 minutes to avoid needing to wake it  up with a button. Not cool.
 Here's the good news. I think I finally found the setting that fixed it.

In the network options there was a setting for Ethernet Power Save that was On. I've turned off this setting and several hours later I'm still able to connect to the web interface and it shows the printer status as in sleep mode.

It makes sense that if this Ethernet Power Save turns off the network connection that you wouldn't be able to wake it up over the network. It's also possible that there is a magic combination of switch and printer that causes the powersave to appear as off to the switch, but some switches may work properly with it. This particular printer is plugged into a small desktop switch in someone's office.


  1. I know that this is an old post, but do you happen to have screen shots of the setting that you are referring to when you say Ethernet Power Save?

    1. Sorry, we ended up returning that printer as it was cranky about alternate paper sizes and ended up being too much hassle for the client. However, the option was named exactly "Ethernet Power Save" in the web interface. I believe it was a setting in the network configuration.

    2. Thanks Byron - very helpful - even samsung website was not clear on this

    3. I tried different settings on my Samsung m2070 network conencted printer. Finally used one that said Wake Up Event. I turned it on and now it's working perfectly fine :)

  2. Go to network>general>ethernet>ethernet power saver.

    thanks Byron, was very helpful

  3. I have had similar problem with ML-2955 and I set this:

    Network Settings -> General -> Ethernet -> Ethernet Speed: 100 Mbps (Full Duplex)
    The default value is AUTO.
    (I do not have Ethernet Power Saver option).

    Additionally I have set on "Machine -> System Setup -> General" that options:

    Auto Power Off: "unchecked"
    Power Save - Wakeup Event (Button and Printer): On
    Power Save: 1 minute (yes that is work :-)

    And my IP is set to static adress and not DHCP.

    After that, my printer goes to sleep after one minute and wakes up when I print something.

    1. this worked for me on a samsung c410 0n wfi. crazy

  4. Perfect, thank you very much, this solved my problem too.

  5. Thanks for your help! You helped me solve my problems with M283X (first) and C410 (second), which I suspected was related to sleep/wake issues. The solution worked with my first networked Samung printer, immediately. I could not get the ability to change the settings for my second networked Samsung printer, which is on the same network. I Google searched, and found that I was supposed to login to get the tab that would allow me to change settings. Okay. I did not login for the first printer. Anyway, I did login for the second printer and that printer now works. Of course, now I had to setup login for the first printer. Still shaking my head at not having to login on the first printer on the first go around.

  6. Reading this has helped a lot. My ML2571N always worked perfectly with static IP. When I upgraded router with base rather than .0.1 I knew I would have to revise IP so opted to enable DHCP. I thought the new router was the problem with not waking up but changing back to static IP has sorted everything.

    Thanks a lot everyone

  7. so glad i found this post!!! i was pulliing my hair out trying to figure out how to resolve the issue!!!

  8. I have a Samsung C480W not waking up from sleep mode. I run the Samsung Printer Diagnostics program that was installed with the driver and is also on the CD. Then it seems working much better. I don't know what was changed. --Dan
