imageCLASS MF753Cdw - regularly loses network connection

[justsometallguy]

This happens daily. The only way I have found to fix it is to restart the printer or unplug it then plug it back in. Has anyone found a way to keep it connected? It’s super frustrating to have to constantly walk over and do this before I can print anything.

Thank you. I went through those steps and will see how it goes.

Great. This is the configuration I use on all of my PC's, Mac's and printers.  By assigning a static IP to the printer on the router, it ensures it will never give that IP address to another device on the network regardless of when the printer was last seen, turned on, used, etc.  

Similarly, installing the printer as a TCP IP device on your computer means it will not have to rely on DNS, bonjour or hostname lookup to resolve the printer's name to its IP.  

The brand and model of your networking equipment also plays a role here.  Some consumer networking gear doesn't do this as good or as well as other networking equipment.  

Last of course is the network adapter in the device.  Over the years I have seen a higher number of issues with the NICs in the MF 751 and 753 devices.  Failing to wake, etc. 

I'm hopeful however that the changes you've made are going to work for you.

OP did you ever find a resolution I have a MF753Cdw II on windows 11 and it is doing the same thing. Static IP, can ping it till it goes to sleep when recovers from sleep no remote connectivity via web or ping. printer acts like it has network from the console. I have disabled power save on the wifi adapter on the printer but this is an issue.

Yes, it’s been about a month. Adding the printer directly to the MB Pro via the static IP seemed to fix it for me.

Great feedback thank you very much!

Unfortunately, the issue has returned, though now it's also not printing from any device - mobile, Mac, or PC. It's showing that it's connected to the network with the same static IP I previously assigned it, and I can confirm that I can access it directly via my web browser using that IP address. However, it simply will not print or acknowledge that I'm sending a print job to it. I've tried power cycling it multiple times, since that seemed to have done the trick before, and I even removed/readded it to my PC using the IP address. I'm about done with this rather expensive paperweight.
