Solution 1: Check the power cord
Solution:
•
The printer may be plugged into a power strip that is turned off. Turn on the power
strip, and then turn on the printer.
•
The printer may be plugged into an incompatible power source. If you are traveling
abroad, make certain the power source in the country/region you are visiting
complies with the power requirements and power cord of the printer.
•
Check that the power adapter is functioning properly. To check the power adapter:
◦
Make sure the power adapter is connected to your printer and a compatible
power source.
◦
Press and hold down the On button on the printer. If the On button lights up,
then the power cord is working properly. If it fails to light, go to
or contact HP support.
•
If you plugged the product into a switched outlet, make sure the switch is on. If it
is switched to on but still does not work, then there might be a problem with the
power outlet.
Cause: The printer might not be connected to a power source.
If this did not solve the issue, try the next solution.
