MF644Cdw & LiDE 400 Problems scanning on both with macOS Sequoia 15.2

[MattPackwood]

I have both a  LIDE 400 and a MF644Cdw, since I upgraded to macOS Sequoia 15.2 I no longer seem to have scanning functionality for either.

I have removed the MF644Cdw and re-added it, installed the latest Scanner Driver & Utilities for Mac V2.15.17 [macOS 10.14.6 - macOS 15.2] and UFR II/UFRII LT Printer Driver & Utilities for Mac V10.19.20 [macOS 10.14.6 - macOS 15.2]

I see the device as a printer and a fax but Not as a Scanner.

For the LIDE 400 I don't see the device when I go to add it as a "Printer or Scanner".

Hello,

If both devices do not show up as a scanner when you click on the option to add a printer or scanner, it looks like there is a connection issue. We would be happy to assist, but we would need some additional information to assist further. You can reply to this message with the information below and we can provide some troubleshooting steps or suggestions. For a more immediate resolution I would suggest contacting support over the phone at 1-800-652-2666. Our agents would be happy to assist.

1. Are you connecting directly to the computer or are you using a USB/docking station. 

2.When you connect the lide400 to the Mac, does it make any noise?
