Why does my HP C6180 All-in-One printer not power up?

Please give it a try. I found what I was looking for which is how to put it in diagnostic mode. The printer in diagnostic mode should tell us what is going on.

• Press and hold the “*” key.

• Press the “#” key and release both keys.

• Display should say “Enter Special Key Combo”

• Press and release in sequence the “1”, “2” and “3” buttons.

• Screen says "support" R0631M

• Press and release the right arrow button until the display says “System Configuration Menu”.

• Press and release the “OK” button.

• Display should say “Hardware failure status”. If not there already, Arrow Key over to “Hardware failure status”,

• Press and release the “OK” button.

• Display should say “Hardware failure status: Clear. Press OK to clear”.

• Press and release the “OK” Button. Message changes to “Hardware failure status Cleared. Press Cancel to continue”.

• Press and release the “CANCEL” button as many times as necessary, so that, either the “Welcome to Photosmart Express” screen appears, or, the “Ink System Failure” screen appears. DO NOT TRY TO PRINT AT THIS STAGE.

• Using the Power Button, turn the unit OFF and unplug the power cable from back of the printer and wall outlet.

• Wait 30 seconds for the power to get discharged and then plug the power cable into the wall outlet first and then into the back of the printer

• Turn the unit on. The printer may display message “USE POWER BUTTON TO SHUTDOWN THE PRINTER” followed by “PRESS OK TO CONTINUE”.

• Press OK. The Printer will start the “ONE TIME INK INITIALIZATION PROCESS”. Allow this process to complete and do not interrupt. Once the initialization process is complete, the printer will print out a Diagnostic Page.

Try this, it should give the printer a hard reset:

1. Before pulling power plug, depress and hold the # and the 6 and them hold down from here on.

2. Pull the power plug, I count to 30 before proceeding, with # and 6 still depressed;

3. Reinserted the power plug with # AND 6 still held down until machine powers down, about 30 more seconds or so.

4. Machine eventually resets (turns off). N.B... ALL settings have been erased including fax and wireless, so you need to set them up at the end, below. OK to release # and 6 now.

5. Press power button. Will come up quickly to the do-not-unplug-power warning, hit OK. Machine will now go through 2 minutes of initialization.

6. If you use wireless, do the wireless setup from NETWORK menu and print the network report which confirms connection as well as that it can print.

7. Set up FAX if needed.

Hope this helps...
