[QUOTE=jon;12426]Starting with your last question - Epson thinks a year is optimal to replace the ink exchanger. If everyone did this annually, their printers would last longer. So no time like now. But if you are going to flush the printer, flush all the scaling pigment into the dampers - then replace them. You should perform the perfect nozzle test prior to replacing the dampers, and use damper replacement to verify that they are not the cause of any jets that will not clear. Always be verifying step by step.
hope this answered your question. Ask away if not![/QUOTE]
Thanks to the suggestions from Walker, Jon, & Datro, I’ve updated the firmware, received and installed a replacement cart for my faulty LK cartridge, performed another init fill with PF, and let PF sit in the heads for another 48 hours. I also replaced the wiper blade.
However, I can’t get a perfect nozzle check on the yellow channel. (The other channels are clear and perfect). I’ve tried 2-3 standard nozzle cleanings, 2 powerful paired nozzle cleanings for Y channel, and 1 CL3 cleaning. I was hoping to get perfect nozzle checks before replacing my ink selector unit and filling with Piezopro. The PF’s been sitting in the machine for a week now. Any suggestions on clearing the Y channel?
