Do you have a service manual? If not, you'll have to download one at

I did not see any error codes like that in the manual , your first 6 digits being 010020 might have been misread for


0A0020 which is an (APS) error code - Air Pressurization System.    This is air pressure that goes to your ink cartridges to help push ink through the tubes to the printheads.

Make sure your air pump is running, remove back right cover, look for rubber air hose going to the ink tube assembly behind the ink cartridges. check those ribbon cables.
