2 boxes are gone

when performing a head cleaing i get 03800500-2F42. I'm aware that he has pushed the previous head over the top, +2800 days, could this have damaged the main board ? I still see prices for main boards at being way to expensive for this repair> $650

prints are still ok ; what to do ?

I would look at the purge unit and/or the carriage unit. Looks like you have a lack of air suction. Check your tubes for air pockets in them

If the prints are Ok I wouldn't worry too much however, what ink is in the machine, genuine or 'refilled?'

its original intkt, prints are great, just nozzle check gives those two down .. it makes me crazy to know why it's not working, the previous head had the same problem

have you checked the head cable/connections?

what units are you trained on?

do you have a manual? ( a MUST on these )

Cap absorbers ever been replaced? If mixed colors on nozzle check, a lot of the time it's plugged cap absorbers. And overdue printheads will short and fry main controller

Kindly check & clean the Cap aborser on the purge unit.If it is damaged,kindly replace.
