Did you get this issue resolved?
I have exactly the same issue and same printer.. it is really hard to get hold of tech in the UK and i am out of warranty.. Just wondering if anyone else has solved this issue as there is not much info about it available.
My printer is set to a limit of 1000 impressions. I guess that is why I get error code 016-519. I can not find anywhere to reset or increase the limit. Manual for the printer does not say anything about it.
Thank you for the help!
