We recently replaced our maintenance station on our Falcon Outdoor. Since then, before we print, we have to use a syringe and pull ink through the waste lines because it appears that the heads are dry. This only works temporarily unless we are printing all day. Come in the next morning, and we have to start the process all over. Also, even after the syringe, our nozzle check shows a substantial amount of lines in it. I don't remember it ever being as bad as it is now. Any suggestions?
