Ink system failure

Try changing the ink cartridges.

If you installed the "HP Support Toolkit" software from the CD-ROM that came with the printer, use this Toolkit to "run a cleaning cycle".
It can print a "test" page, to show you which colours _do_ work, and which do _not_ work.

If all else fails, then find a qualified printer technician.

Turn off the machine using the power button, unplug the power cord from the back of the machine, remove the ink cartridges, wait 2 min, plug the power cord back in, press the power button to turn on the printer, wait for the printer to prompt that the ink cartridges are missing, then replace the ink cartridges. If this doesn't clear the error you may need to re-prime the ink cartridges. There is a good explanation of how to do this at http://www.ccl-la.com/blog/index.php/hp-photosmart-ink-system-failure-1/.

1. Turn the printer off for few minutes then turn it back on
2. Clean ink cartridge
3. Update drivers
4. If nothing works, repace the battery

See http://www.hp.com/pageyield/articles/us/en/InkExpiration.html on how to override error.
