Ink system failure

This is an Ink System Failure message. I would try this guide. 'Ink System Failure' or a '0x...' or a 'C2...' Error Message Displays on the Front Panel. To help resolve the issue.
If that doesn't work, please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region. http://www.hp.com/cgi-bin/hpsupport/index.pl.

Its tricky mechanism, once printer detects ink system failed it cannot be resetted. Do this take out cartridges from printer., open right cover., find out logic card., remove cmos battery., wait for 5 minutes., refix batyery., power on the printer., follow the screen messges ... I hope it will solve the issue..

HP Photosmart C7180 will not accept new '02' yellow ink cartridge and repeatedly states 'printer does not have enough ink to ensure printer health. The empty ink cartridge must be replaced to resume.' This is the 2nd HP '02'yellow I've bought and it continues to say the same.

I get the ink system failure message on my hp c7180 as well as an error code of oxc18a0306.

it could be a viros or a printer jam
