Hello. I hope you can help.
My EPSON 9600 Ultrachrome was having a re-occurring clogging issue that was evident in the print head tests. After a series of cleanings I would get it to start printing but only have the problem re-occur the next day. As the ink system has never been flushed on the printer I thought it was time to do a complete cleaning. I ordered the PiezoFlush product and made use of empty carts to complete the flush. I followed the initial fill process and everything appeared to start off great. The PF product was pushing into the ink tubes and I got a maintenance tank full of ink. So with that I thought everything was going well. I left the material sit in the system for a couple of days to help break down any remaining ink product in the system.
After letting it soak for a couple of days I was starting the process of testing the printer to see what kind of results I was getting with the PF product. I completed a test page of the 7 primary colors and Magenta was the only one to print. I had nothing from any of the other colors. I have made sure the cart are primed and that the vents were left open. For the most part it appears that the tubes are free of air except for the LT Cyan that has a huge air pocket in it. I have re-tried the initial fill cycle to see if it would move any ink with no success. Repeating the ink print test I can see the air pocket in the LT Cyan tube move back and forth but not flow.
I had submitted an email in to your online chat system and received a quick reply from Jon stating the following:
if your cart vents are open and if your carts are primed and air is not preventing the ink from leaving the cart because the ink channels are full of air - then this means that your pump in the capping station is not drawing the ink. IF you tried an INIT FILL and nothing is happening - I suspect the pump in the capping station is not drawing ink.
As I am getting at least one color to print would the issue still be with the pump in the capping station? I thought it may be the dampers based on my research. I thought the flush may have pushed a bunch of residue in to dampers and clogging them. Before completing the flush I was really only having problems with two ink colors clogging. Now I an issue with six of them.
Any help you can offer to help diagnose the issue would be most appreciated.
