MF753CDW II – Network Not Recovering After Sleep Mode

[shdwlark]

Hello,

I’m reaching out for guidance on a new MF753CDW.

I’m hesitant to post since I’ve seen similar reports without clear resolution, but I’m hoping someone can help.

Here is what I am experiencing:

• Brand new MF753CDW II

• Static IP configured

• Connected via 2.4 GHz WiFi

• 2.4 GHz and 5 GHz are separate dedicated SSIDs

The issue:

• When the printer enters sleep mode for extended period of time (Deep Sleep), it does not properly recover network connectivity.

• If I manually wake it using the LCD screen, it still shows WiFi connected.

• However, no device can reach the printer.

• It does not respond to print jobs or pings.

• I must power the printer completely off and back on to restore connectivity.

Additional notes:

• Tested from 5+ devices

• Windows and Linux systems

• Same behavior across all systems

• At network level pings are 100% when awake but in deep sleep no pings are returned.

• If I prevent the printer from sleeping (currently set to 120 minutes), it works 100% reliably

It appears the printer does not properly rejoin the network stack after deep sleep, even though the display shows WiFi connected.

Has anyone found a solution for this?
Is this a firmware issue, sleep setting issue, or known bug?

I have experienced the same issue with my Imageclass MF753Cdw II printer.  Although, it doesn't happen all of the time.  It will wake up if I tap the touch screen but, at other times, tapping the touch screen will not wake up the device.  When this occurs all print jobs sent to the printer were stuck in the queue.  Shutting the printer off and thern on clears this issue.  I have updated the firmware with the same result. (I had to update the firmware using my computer, directly connected to the printer, because I kept getting a communication error when using the internet.)   It appears that other posts have pointed to a network setting.  Since I'm a novice, I don't know where to turn to correct this issue.  Please help!
