Mimaki cjv150 dot position lines wonky

[Mathew Atkin]

Hi,

Has anyone ever come across wonky lines on the dot position adjust. Recently our machine has started to print certain patterns with wonky lines (see attached image). It looks like some sort of calibration issue but I cannot understand why it would just start doing this.

Any help would be appreciated, Thanks Again

I have the same issue with this, did you manage to resolve this or if anyone has any insight ?

Best bet is to find a service manual and check head voltages and run alignment procedures. Unfortunately, no service model for this model of printer in my stash.

Ok cool thanks . I'll check that out ! Are these the numbers that the voltage should be ?

Most modern heads have a preprogrammed factory voltage bias that can vary from head to head. Over time, with wear and use, retuning is sometimes needed. You might be able to default to factory settings, but that can make things much worse in some instances.

The voltages on the chart shown are just system voltages, not particularly for the heads. Voltage adjustments are typically done in the ADJUST menu from my limited experience.

The newer JV150/CJV150 (300) machines do not have head voltage adjustment. At least not in the service manual. The section in the service manual just has a bit of Chinese text that translates to "Description omitted for development confirmation functions. Do not use.". I have not looked in the #ADJUST menu to see if is actually adjustable on ours....

To me it looks like the material just buckled or got a bit of a ripple in it for a second there as the set of lines below it look fine as do the set after.

Unfortunately, it's quite consistent for it to be the media . I'm swapping heads this weekend and hopefully this will solve the issue .
