Seeing if anyone else has ever had this issue, this is the first for me. Roland sp-300 has been sitting idel for about a week, just cutting, no printing. I went to print today and nothing, wont bring the ink from the cartridges, which are full. did several light and 1 heavy duty cleaning, still no results. Went thru and checked all the dampers (OK)... Used a shringe to make sure ink lines are full. This unit has a new pump as of 6 months ago, installed by Roland rep. When doing cleanings, I do not see any ink being pulled into the lines nor in the ink disposal bottle. Any help appreciated.
