Troubleshooting with Control Panel Messages Job Cancel Button Attention LED Ready LED Go LED and Button NOTE: Control Panel LED Messages LED patterns provide both status and error messages. The LEDs can be in any one of the following states: Off On Blinking The following Control Panel LED patterns indicate various conditions of the printer in preparation for, or during, printing. If the Attention LED is on, the printer is experiencing an error. The messages are grouped according to error type - status, attendance, continuable, service, and accessory errors. In many cases the error will provide direct information about the defective component. If the printer's LEDs indicate a continuable, service, or accessory error, secondary information is available by pressing the Go and Job Cancel buttons simultaneously. Releasing the keys will return to the original error state. Transitions in error states are marked by the LEDs flashing off briefly before displaying the next pattern. Secondary information about 79 service errors (unrecoverable firmware errors) is not included in the scope of this document. If a 79 Service error occurs, replace the Formatter. See "Continuable, Service, and Accessory Errors" (page 97) for secondary information about each of these three types of errors. 94 Chapter 6 Troubleshooting C4170-90959
