Mimaki JV3 black head overspray

Hi ,

please check the testing photo, Our printer technician followed the alignment tests directly from the manual yesterday. (head slant, Print adjust 2 x, print adjust 2 y, adj. y si, adj 2 y re, adj 2 y bi...etc. ) The concern is the black shows 2 rows of dots printing on each test and the really odd test was the variable 2 print adjust 2 y si shows the extreme dot pattern that does not make sense.

anyone know this situation?

extreme values within the alignment procedures would cause this.
you should be replacing the existing values with the alignment results, not adding to them, and hopefully you are using the right values (which is all +/- decimals, I don't think I have a single whole number in my alignments).
 
In Variable Drop printing heads fire several drops in rapid succession and these are supposed to combine in flight and all land in the same place. Yours look like they are breaking apart before landing:

A few things to check:

- check that you entered the Head ID
- make sure that the Head Height is correct (excess gap will cause this)
- make sure head is mounted flat (not tited due to a chunk of old ink)
- check quality of cables
