(First Digit = 6, 7, 8)

following:

All Ink Cartridges installed are NOT of the wrong type i.e. 
wrong model.

If you replace or reseat  Ink Cartridges one at a time and the  
error persists for all cartridges, this indicates a hardware 
problem. Do the following:

Station and the ISS PCA.
2 Remove the Service Station and check that the connections on 
the floaters are clean.
