The x420xlx.dll file is a component of a driver for the Xerox WorkCentre 415/Pro 420 XL from Xerox. A driver is a software tool that helps your computer to communicate with outside hardware, such as a printer.
If the driver isn’t installed or isn’t working correctly, you won’t be able to use the hardware that needs it. An error with this file may disable the driver for this printer. You can try to reinstall the driver if you have it available, but you should consider cleaning your registry.
The registry keeps track of all the files installed on your computer. Each file has an entry in the registry that tells Windows how to find and use that file. If there is a mistake in an entry, programs that need the file will not be able to run.
