Clogged Nozzel detected error

[[email protected]]

On our Epson 9900 we keep getting Clogged Nozzel detected error, Yet nozzel check is fine. Our repair service technician consulted Epson Tech Support and they recommend new print head. Has anyone experienced this problem?

A firmware update resolved this issue for me in the past but on another model, not the 9900.
