No nozzle check
 
Perfect prints Saturday,
untouched Sunday,
Monday, no nozzle check.

During a cleaning it looks like all channels are spraying in the capping station.

Filling the capping station with cleaning solution, it is flushed during a clean.

Can see ink moving in the lines during a cleaning.

Zero ink printed during a nozzle check.

My first thought was capping station, how do I test that? Other ideas?

Thanks

You may have blown the F6 fuse on the Epson motherboard. Expose the Epson motherboard and see if there is a replaceable fuse soldered on in the F6 position. If there is then test the fuse to see if it is blown. Replace it with a 375mA slow blow fuse. If you do not have the replaceable fuse holder soldered onto the board then you can send the motherboard in to us and we can install one for you. Give us a call 877-202-0886. Thanks.

The fuse is not replaceable. It seems to be good, tested with an ohm meter.

Thanks for your help, the symptoms do sound like a blown F6 fuse.

If that fuse is good then I would try replacing the capping station next.

Can a capping station be stored after being used?
I have a new spare capping station but if my current one turns out to still be good will it brick from sitting after having ink in it?

I have never let one sit for too long and put it back in. My guess would be that it depends on how long it sits. You said that when you fill fluid in the capping station it is flushed thru with a clean. That usually means the capping station is good. But, I would check that the tubes are connected under the cap. The fluid could be just draining out during the clean rather than the pump pulling it thru. Also make sure that the printhead is sealing over the cap properly. If the printhead is not firmly mounted in the carriage then it is possible that it not able to form the proper seal to prime the printhead.
