Need Help FUJIFILM ACUITY EY - Timing Alignment- Manual alignments

[CLOCKG]

Hi Everyone

Last March i installed a brand new Acuity EY, it has been printing beautifully until now, the Black 1 printheads show missing nozzles, but this missing nozzles jumps from one nozzle to other, i have checked the ink and vacuum lines an all is ok. I also cleaned the electrical connections (flat cables) but the results are the same, performed an ink filter bleed, performed several purges, i tried also increasing a bit the printing voltage for this printhead but it was of no help.

Since the is no tech support representative here, i am planning to use one of the white printheads and replace it with the black one (white is not often used), but now i got stuck because in order to do the printhead calibrations after been replaced, i need to use a scanner and a software tool.

Does anybody know if there is a manual procedure for that Timing Alignment calibration? Or do you have any other possible solution for this missing nozzles? I know there are only a few nozzles, but when printed on Backlit fabric... you can see the lines on the prints.

I attach a head test. Printheads are toshiba CA4LH

There is no way to do the timing adjustment manually.
The scanner alignment tool can easily be found on the internet and the scanner is a home grade one. You need the service dongle to set the head parameters if you swap.
Where are you located? A FF comprehensive technician should be available everywhere.
