Power-on checks
When you turn on the product, if it does not make any sound or if the control-panel display is blank,
check the following items:
●
Verify that the product is plugged directly into an active electrical outlet that has the correct
voltage. Do not plug the product into a surge protector or power strip.
●
Verify that the power button is in the on position.
●
Verify that the formatter is seated correctly.
●
Remove any HP Jetdirect or other devices, and then try to turn the product on again.
●
Ensure that the control-panel display is connected.
●
Check the two fuses on the power supply.
●
If necessary, replace the power supply.
●
If necessary, replace the DC controller.
