1 nozzel Not Firing :(

[Dice]

We had a Head Strike on some Banner Material after a banner print got caught on the media guides some how.

After which a Test Draw showed that many nozzles went firing, but after 2 hard cleans, all but 1 came back to life. We've since done about 5 hard cleans, and 2 head washes for 20 minutes.

Nozzel still won't print . I can see the impact on some prints.

Any tips on how to get this nozzel firing again? Is a head replacement the only option?

Try an overnight head wash.

Also you might try using the syringe method to draw ink through the head.

In the end if it's not firing due to damage, then replacement is your only option.
