I have an HP D135 printer that when you turn it on, all the lights on the panel start blinking and the display reads to turn power off and on. Every time I turn power off, then on again, I get the same result. I've tried unplugging it and replugging it back in, same result. Any help is appreciated.

Have you checked HP web support? I did. Here's what they say: "Turn Power Off then On" error messagesback to top of page This may occur in a low power situation. Try the following actions in order to determine the cause: 1. Check for jams in the unit or in the ADF (if applicable). 2. Verify that the computer and the all-in-one product have a three-prong power plug. 3. Remove the product cable from any power strips or surge suppressors, and plug it directly into a grounded (three-prong) wall outlet. 4. Disconnect any other devices attached to the parallel port, and uninstall any drivers or applications associated with them. Some devices use a software key that plugs into the parallel port. This can cause an error on the all-in-one. 5. If the all-in-one has an ADF with an external cable plugging into the back of the product: 1. Turn off the unit and unplug the power cable. 2. Unplug the ADF cable from the back of the product. 3. Plug in the power cable, and turn on the power. * If no change, the problem is not the ADF. * If the problem clears, turn off the all-in-one, unplug the power cable, and reconnect the ADF. * If the error returns, the ADF is defective. Contact HP Customer Care to get the ADF replaced. 6. Disconnect the computer parallel cable from the back of the all-in-one and try to turn on the all-in-one again. The computer may be grounding out through the parallel port. If this corrects the issue, check the grounding of the computer and outlet. If the problem still exists, contact HP for assistance.

Sorry I didn't include that I had already gone to the HP website and did all of the above. The only number I found to call was for printers still in warranty. Mine is no longer in warranty.

I'm assuming that nobody else has any advice for me?
