With older machines, I think the screens are partially clogged, allowing
thin dyes (and cleaning fluid) through, but not pigments.  I recommend
putting MIS cleaning fluid carts in the printers for a week or more.  Run a
cleaning cycle about once a day and print a few purge patterns daily, but
basically, just let the fluid try to dissolve away the old ink on the
screens.  It sometimes works.
