all my cables are pluged in but i have no power to printer lexmarkz43
Make sure all the power cable connections are tight first. Often where the power cable connects to the back of the printer, the cable can come loose. If all connections are tight, your power cable could possibly be bad, but as well so could the power supply of your printer.
You could also try and leave the power cord completely unplugged from the printer and your power source for about 5-10 min.
