I’m trying to resurrect a 4880 that has been sitting. Most of what I’ve done so far, soaking heads and running flush through the lines, has done from the front panel. I was asked by Wells from IJM support to try producing a manual nozzle check, which required me adding the 4880 as a printer on Win 10, which I did. I was successful adding both through ethernet and USB ports. However, when I try to do a nozzle check, the printer just sits there, and the eventually I get an error in the printer queue on win 10. Wells suggested I post the question here. I hope this is the right group.
