JOB CANCEL

Figure 2 Control panel layout

Light patterns provide status and error messages. The lights can be in any one of the following states:

Off			On		Blinking
Figure 3		Light states

The following control-panel light patterns indicate various conditions of the printer in preparation for, or during, printing. If the Attention light is blinking, the printer is experiencing an error. The messages are grouped according to error type: status, attendance, continuable, fatal, and accessory errors. In many cases, the error provides specific information about the defective component.

If the printer lights indicate a continuable, fatal, or accessory error, press GO and JOB CANCEL simultaneously to display additional error information. The lights flash briefly to indicate transitions in error states before displaying the next pattern. Secondary information about 79 fatal errors (unrecoverable firmware errors) is not included in this document. If a 79 fatal error occurs, replace the formatter.

Continuable, fatal, and accessory errors

Additional information in the form of a secondary error message is available for each of the following three types of errors:

•Continuable errors

•Fatal errors

•Accessory errors

The first entry in each of the following tables shows the primary error light pattern. The remaining entries illustrate the secondary error messages. The tables also contain information that typically appears in the status log area of the self-test/ configuration page.
