You'll click on the third plus sign on the page (+) because your message DOES include the words "ink system failure."

From there, you'll choose, by looking at the pictures, whether your printer has a removable print head.

You'll click on the appropriate answer -- yes it does, or no it doesn't,

Then, you'll identify which print cartridges your system uses, and THAT will take you to the proper troubleshooting steps for your printer's specific configuration.

The fix may be something you've already tried -- turning off the printer and unplugging it (but did you unplug it from BOTH the unit AND the wall, and then did you wait at least 15 seconds?), or the fix may be to service the printer.

Good luck! :)

I had this same exact problem. Try doing:
1. Unplug the power cord from printer.
2. Hold both o.k and Cancel simultaneously.
3. Plug the power cable while holding the buttons.

I had to go through multiple tries of the solution above. I turned it back on, it shut off and I turned it back on again. I tried to print something and sure enough, it did a maintenance cycle and it works again.

This did not work the first time but after 3-4 times of doing both, TA DAH, it went through a lengthy maintenance cycle and then started working. Persistence paid off.
