Hi - When printing an nozzle check on our Epson 9600, I am getting no MK printing at all, and only the lower two lines for LK. See below for what I've already done to try to get it working. All of the other colors are fine. My question is whether it's the head, or if there is something else to check or try before buying a head or another printer? The 9600 is really all the printer we need for what we do. It would be nice to be able to fix it.
Background: I was flushing the 9600 with Piezoflush in preparation for switching to your Pro ink. I have no reason to suspect that the flush has caused this problem. I just want to mention it so that folks will know how I got here and what I've done, so far. MK and LK were not producing perfect nozzle checks prior to the flush. MK was showing a few dots, and LK is about the same. I have replaced the MK and LK dampers, just to eliminate that variable. The printer is still set up with the Piezoflush carts. Piezoflush is being pulled through the MK and LK lines during cleaning cycles. I removed the head and gently pushed some flush through MK and LK. Nothing seems amiss. No apparent clogs. I cleaned the contacts on the ribbon cables. There are no errors being displayed. The printer has been running fine, aside from occasional clogs due to sporadic use. We try to keep the capping station damp, and it's always recovered after a couple of cleaning cycles.
