imageCLASS MF751Cdw has to be powered off & on for users to print

[tjfitz68]

Since this printer was purchased, which wasn't that long ago, it's had to be powered off and back on every morning in order for the users to print. It's on the network. I've maxed out the power saving settings to no avail. Firmware is up to date. Right now the driver version is 2.90. I'm aware that 3.20 is available but I haven't installed it yet.

Greetings.

I think I mentioned this elsewhere but it's certainly something to try.  If I'm not mistaken Windows uses Port 9100 by default, but the printer is set to use 515.

• Change Protocol to RAW (Port 9100): In the printer's network settings on your computer, change the printing protocol from LPD to RAW, which often resolves waking issues.  I think the printer comes set to use port 515 LPD by default.  

Try changing the printer's listening port to 9100. You can do this in the remote UI or from the Canon print app.

Yesterday morning I updated the printer to the latest firmware. I don't know what it was before but it's now: Main Controller is Ver. 8.01, Boot ROM is Ver. 02.04, DCON is Ver. 10.02, Language is Ver. 01.17. 

This morning we were able to print without turning the printer off and back on. We are testing again in the morning. I will post the results here.

This morning, 2/26/26, HR was able to print to the printer without cycling power. Hopefully the recent firmware update solved our problem.
