The printer driver comes on installation CD when buying a new copier. If you are using it as a printer, insert the CD inside the CD-ROM drive and click open the file written set-up and follow on-screen menu. Connect the USB cable when prompted to finish your installation. Now you can print using your Sharp AR-5316 and that is the driver for it.

Hallow, this is a problem with the exposure lamp on the document glass which is not working or if it is lighting, it is not sensing the white mark on the cover which is above it.
Remedy
Please check if the cover that locks the glass is well screwed or present.
Check if the copy lamp is lighting and replace with a working one.
Check if its cable is not disconnected on its power board located beneath it.
Replace the main board of the machine.
Nb use that sequence to solve your problem and good luck.
