Open the printer and remove all cartridges and make sure all prepackaging tape has been taken off them. Then sharply unplug the printer from the wall outlet while it is still on, and disconnect all cables from the back of the printer. Use a q-tip dampened with warm water to clean the copper contacts on the cartridges and in the printhead inside if you see any. Keep cleaning until no ink comes off on the q-tip

Then, remove the printhead:

Take care not to touch the nozzles on the bottom, and with a lint free cloth that is slightly dampened, wipe the electric contacts on the back of the printhead from bottom to top, in one direction.

Then go ahead and reinsert the printhead. Finally, reconnect all cables to the back of the printer. Now while holding down the stop/cancel button, or just the power button if you don't have those, plug the printer back in to the outlet, then release the button. Power on the printer if it doesn't do so automatically. Then, reinsert the cartridges firmly so they click, and make sure the ink lamp is a solid red when you reinsert them:

Then follow any onscreen directions if given then see if the error is gone. Please reply back and let me know if it is not and we'll continue.

Hi there,

We seemed to have made a little progress, can you let the printer sit for about 15 minutes and see if it eventually starts procesing? If not, please let me know and we'll continue right away.
