The 6180 hasn't had a driver since 10.11 and hasn't been sold since 2009. There is very little chance of getting anything compatible now. I have no idea how you could have been doing it in 10.14
Phaser 6180MFP-D no longer supported. Upgraded to Mac OS Catalina and can no longer scan (print works). Is there a workaround to get 64-bit drivers that will allow me to scan?
