G7020 keeps going out of head alignment

[LMarkoya]

I have realigned my G7020 several times , have tried new print heads and after realigning got good results for maybe 20 pages, not the alignment deteriorates after every alignment that looks good for the alignment test and goes bad after a few pages...and hints?
