Install fails or stalls?

Run the Konica Minolta bizhub 420 driver installer as Administrator. Clear pending print jobs and restart the Print Spooler (`net stop spooler` / `net start spooler`) before retrying.

Device not detected?

Confirm the bizhub 420 is powered on and networked, then add it using its IP address via a TCP/IP port. For USB, try another cable/port and install the driver before connecting if prompted.

Remove old Konica Minolta or generic printer drivers for this device in Print Management, delete the old queue/port, reboot, then install the matching 32/64-bit bizhub 420 package.
