After doing a large run (350'+) of bright red prints all weekend long on our seiko 64s we just needed to finish one last print to complete the order. The machine had been sitting overnight and we did the regular cleaning and maintenance, and fired off the print. It started beautifully, printing a rich vibrant red, however about 6"-1' into the print the magenta print head crapped out. Running a cleaning cycle would fix it for the next foot or so then it would go out again. Printing the nozzle test showed that it was only the right side of the print head that wasn't firing properly. On close inspection is appears that the nozzles are spraying erratically if at all. Attached are some pics of the issue. Does anyone have any ideas why this is happening and how we might go about resolving the issue?
