Go to the Sharp web site, find your device and load drivers, download the driver for your device ensuring it is compatible with your OS.
Follow the on screen instructions.
To resolve this issue, you can try updating the printer driver to the latest version. You can download the PCL 6 driver for Sharp AR-M420u from the following website :
