HP Photosmart C5180 All-in-one error Oxc18a0301 I replaced 2 ink cat with proper ink. Now I get error oxc18a0301 I have the same problem with the HP C7180... I try to do unplug, move the cartridge, unplug... but I still have the same warning message??? message error Oxc18a0301

I tried all of the above, but nothing worked. The error message continued to appear as soon as I would turn on the printer and blocked whatever function. I had it back in the shop to service it, but they just told me not to spend any money on it and buy a new one. So did HP itself when I contacted them.
I finally ran accross this, which took of the errore message and now actually the printer is working like before.
I had the USB disconnected, the power cord disconnected as well and all the cartridges taken our, just as written in the instructions above. But then turning on the printer again, I hold down the OK and HELP button. And that did the trick for me: My C5180 would turn on and then switch itself of after a while. I then stopped to hold down the buttons and turned it on normally (still no USB connected) It did all the setup (language, country, ecc.) and then finally told me that the cartridges were missing. I reinstalled them and turned back to normal.
Hope it'll be of help for some of the many desperate HP users.

I tried everything mentioned above and the printer still does not work - the printer is about three years old but rarely used... is this just a faulty product from HP?
