"Unable to Print 8F"

The message "Unable to Print 8F" will appear on the display for one of the following reasons:

     ii.  Mechanical malfunction.

To attempt to clear the error, continue to step 1.

1.  Using both hands, use the finger holds on each side of the machine to life the scanner cover into the open position.
