Hi Dixon, It sounds like you are having a rough go of it! I am sorry to hear of all these problems, I'll try to help you with your concerns and get your printer diagnosed. Let me give you some back ground on these printers (information you may already be well aware off), the X9XX printer platform was designed with a "Piezoelectric" head, a full description can be seen here at this nifty web-site called MyX900.com http://myx900.com/x900-printhead-revealed/
This also applies to Richard who posted this thread originally. The print heads in the X9XX printers have been notorious for clogging nozzles, we've had several of these print heads fail in our studio and R&D. We have had success using our Piezoflush solution in these heads, but not 100% success, sometimes the heads are too far gone to bring back. In this case, you both have the following options for your printers:
1.Call Epson if your under warranty and have them come diagnose and replace the head
2.Purchase the extended warranties for these printer platforms either when you purchase the printer OR when your Original Manufacture warranty is about to expire (1 year after purchase) Epson will offer you the extended warranty again, buy it! It is a whole lot cheaper then a new head!
3.Try to get Epson to sell you a replacement head for your printer and replace it yourself
4.Re-purpose your printer into a Piezography printer, you have options with 6-10 channels
5.Don't give up just yet, let your printers sit for 24-48 hours with the flush at the head, clean your capping stations, wiper blade and bottom of the print head and perform a NC after start up
Dixon-It sounds like you are dealing with some major blockage in your system somewhere (possibly your head OR dampers) that is not allowing the flush through the lines. Please open the front cover and examine the ink lines for ink OR flush present in the lines. This will verify there is NO flush leaving the cartridges. Also, how long did your printer sit with ink it is before you tried flushing it?
Richard-Please go ahead and perform another Init. Fill and let me know how your NC looks, keep an eye of your waste tank, you will have to empty it and reset it after the 2nd fill for certain depending on how full it is before you start.
