A TWAIN error belongs to the scanning application and driver interface, not the print queue. Confirm that the scanner works in a basic app before installing model-specific TWAIN software.
Isolate the application
Try scanning with the OS app or manufacturer's utility. If that works, the hardware and basic scan route are likely available; check whether the original application requires TWAIN instead of another interface such as WIA.
Check the exact package
Search the maker's support page for your full multifunction model and OS. Some packages provide a scan driver but not a TWAIN component, and a 32-bit application may need different support from a 64-bit one.
Do not mix devices
A similarly named printer series can have different scanners. Avoid third-party driver bundles and check the application's own support when only one program shows the error.
