The x420xlc.dll file is part of the User Interface Core of the printer driver for the Xerox WorkCentre 415/Pro 420 XL from Xerox.  A printer driver allows your computer to interface with a printer and tell it what to print.  This file is part of the User Interface of the driver, which is the part of the driver you can use to make adjustments.

When the x420xlc dynamic link library file has errors, you may have trouble using your printer.  To fix this problem, you can either reinstall the driver or you can try cleaning your computer’s registry.  Your Windows registry is the information booth of your system, keeping track of all the programs installed on your computer.  Windows uses the registry to find files to run.
