I received the Piezo Flush solution & cartridge for my 7900. Unfortunately there was no syringe tip/adapter which is necessary to bleed the solution from the cartridge, so I used one from the Light Cyan ink & hope that is OK.
I started the 7900 in the Maintenance Mode and then in the Menu > Cleaning > ran “Init. Fill”. I was surprised it takes only seconds to run this so ran it twice.
I then went back into the Cleaning Menu & found the tool to clean pairs of ink nozzles. But, under that menu there are four options; CL1, CL2, CL3 & CL4. Are these “strengths” of cleaning with CL4 being the most powerful? I want to be sure to introduce the Piezo Flush into the nozzle so ran both CL1 and CL4. Now I wait 48 hours for the Piezo Flush to hopefully clear the nozzle. Suggestions/comments would be welcome. Mark Weidman
