I recently was getting horizontal lines (in direction of head going back and forth) on my prints. Would clean and then they would come back after 1-2 prints. I had never changed out my original dampers and decided it was time.
1: Changed out all dampers
2: Installed new cleaning unit, wiper and flushing station.
Got back to printing and all went well. Continuously printed about (100) 13"x 25" spreads with out issues. Horizontal lines came back after continuous print #100 or so. Stopped printing. Did a nozzle check and indeed had some drop outs. Did a cleaning and seemed to fix it and now I see hints of horizontal lines coming back.
No leaks that I can see inside the head area....
At a loss here...any advice would be much appreciated.
On another Random note..Love the 4880's - serious workhorse. With all this epson lock out silliness I went looking for some old 4880s - One has come up. Very low usage only 3000 prints and it all parts listed with 5 stars. Thing is, it has been sitting about 12-18 months no usage and will not print anything at the moment with a nozzle check. Hard to say I know, but is it possible to bring it back from the dead with flushing, soaking the head over paper towel etc? Are these heads resilient better than the 4900? What in your best guess are my chances percentage wise of getting this thing back up and printing?
Or just wait until you guys come up with carts on the 4900?
