079 error
Oh dear.
I have had this before. I installed a New Main Board (did not fix) so we put old one back in
There were lots of other (unnecessary) things done: Maint station, head etc, etc, that cost me alot of money by a tech (company that I will not name - still spitting nails...)
Then we put in new CR board - which in turn gave an error code that main board was bad so we put the new on back in.
I have, however, recently been told that it may have been the "encoder strip"
Im not familiar w the 1304 (I have 1204) but see if there is ink on the clear strip - reply back if you cant find.
Luck to you!
