Power-on checks

Turn on the power. If the control-panel display remains blank or if it displays random patterns or asterisks, perform the power-on checks to locate the cause of the problem.

1.Verify that the device is plugged into an active electrical outlet that delivers the correct voltage.

2.Verify that the power switch is in the ON position.

3.Make sure that the main fan runs briefly.

●If the control-panel display is blank, but the main fan runs briefly after the power is turned on, print an engine test page (see Engine-test page on page 165) to determine whether the problem is with the control-panel display, the formatter, or other components.

●If the main fan does not run, check the ECU connections. If necessary, replace the ECU. See Engine control unit (ECU) on page 88.

4.Remove any HP Jetdirect or other EIO cards, and then turn off and turn on the device.
