Hi
This error comes up when there is a ink system failure i.e. when the printing mechanism is not able to work properly
Please click on the following link to resolve the concern and please make sure that when you perform these steps the printer power cord is connected directly into the wall socket and not in surge protector or the extention cord

1. Remove the cartridges from the product.
2. Wait for the 'Insert Cartridges ' message to display on the control panel.
3. Disconnect the power cord from the back of the product.
4. Wait 60 seconds.
5. Reconnect the power cord. If the product does not automatically turn on, press the Power button ( ).
6. Reinsert the cartridges, and then close any open doors on the product.
7. If you receive a prompt to print a calibration page, do so.
8. Reconnect the USB cable to the rear of the product, and then try printing again.

if you want a good printer get a HP all in one very reliable your ink cartrdge print head burned out and you have to buy a replacement head about $50.00 US plush shipping.

This can be a failure of the firmware which means the printer is in hardware failure status but it can sometimes be fixed. Follow these steps EXACTLY as written.

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.
Display should say “Support” and display the FW rev (something like R0631R)
Mine reads 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. PLEASE 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. Good Luck!

There is one fix for the 0x errors and it doesn't always work but this is the only option.
