You could try opening the printer, then removing all the ink tanks.. Then clean the electrical contacts on each ink tank.
Also, with the printer open, look under and around the printhead and inside the machine for any debris , paper, etc.
before installing the ink tanks. Unplug the printer from power completely and wait 3 minutes. Then plug it back in, turn it back on, reinstall the ink tanks and t hen test. Do you still get the error?
