DIAGNOSTIC TEST MODES
G031/G032 4-26 SM
4.8.3 DETAILED DIAGNOSTIC MODE
Entering Detailed Diagnostic Mode
To enter this mode, turn the machine off and on while pressing the “On Line” key
and the “Enter” key together.
During the Test
While testing, the machine displays the component being tested.
If the Power LED blinks, the test is proceeding without problems.
If the Power LED does not blink, a fatal error has occurred. If the machine has
detected an error, the machine displays the error code (e.g. 0101) on the operation
panel, turns off the Power LED, blinks the Error LED, and stops the test.
If an error occurs during the test, press the “Escape” key and the “Form Feed” key
together to continue the test. However, if the error is one of those in the ‘Power-up
and Detailed Diagnostics Modes – Program Execution Errors” table (see section 7,
‘Troubleshooting’), the test cannot continue.
If the Centronics or RS232C loopback connector is not plugged in, an error will
occur for the device with the missing connector
Print Log Output
The print log is printed automatically after the detailed diagnostic test has finished.
