Unclogged pk and mk

I filled an mk and pk cart with piezo flush and ran one cleaning cycle and unclogged both blacks. Now what is the best way to flush out those lines to reinstall the proper carts?

If you unclogged by running a “cleaning cycle” rather than an INIT FILL as we instructed, you probably did not have a clog as no PiezoFlush was used because none would have moved enough to encounter the clog. It may be instead that the PiezoFlush filled carts are allowing the ink to be pushed through the system whereas your old carts were not.

If you mean instead to write that that you ran the INIT FILLS as I instructed and cleared both ink positions, then you could do one of two things:

  1. run the INIT FILLs to replace the inks
    or
  2. to waste less ink in all the other color positions , run a series of black ink mode changes until both channels no longer print pink.
