If a problem occurs, a typed message is displayed on the
message display and an indicator starts to flash on the control
panel.

The flashing indicator informs you of the area that needs
attention.  Follow all the messages to correct the problem.

You can also view the status code that is associated with the
copier problem by pressing the 0 button.

Once the status code appears you can refer to the status code
procedure in the section entitled 

Clearing the status codes to

solve the copier problem.

Note:  When the status code appears, use the first two
characters to identify the status code.  (Example F1-1, you would
go to the F1 status code procedure.)
