If the printer is turned OFF and back ON after changing the USB
ID, the computer (Windows) detects the USB port used to connect
the printer as a new port and automatically copies the printer
driver as xxxx (copy x). If you need to perform another adjustment
using the Adjustment Program, exit out of the program and select
the “copy x” driver, then restart the program.
