I have a reoccuring problem with nozzles randomly dropping out midway through a print on my 9900.
Nozzle check is always perfect before I print.
There is no pattern to which nozzles are dropping out, it's always random. Also no particular colour, also random.
I've spoken to an Epson service tech, he suggested the 3rd party ink / cartridges could be a problem.
Could it be the carts not pressurising properly or a bad seal somewhere allowing air to enter the system?
Many thanks in advance!
