Kyocera copy machine prints all black pages??????? How to fix???

This is a common problem normally caused by the failure below-

The lamp that normally illuminates the original has probably failed.
The machine is producing what we call a 'sky copy' if done on a working machine.
The cover is left open and no original is placed on the table, causing little or no reflection back to the drum or sensors.

Leave the cover open, run a copy to see if there is any light coming from the scanner.

If not, you need the lamp replaced.
