- In JV400 series, you can adjust the height of the head to L (1.8mm), M (2.3mm), or H (2.8mm).
Loosen the screw at the front of the head and rotate the right-side lever to make adjustment.
For details, see "Operation Manual". Also, please see the video "Setting a roll media." as well.
* Basically, the height should be set to L (1.8mm).
Too much gap between media and the head nozzle may cause ink droplets (mists) to spatter, impacting the drawing quality.
* After changing the head height, be sure to check the [DROP.POScorrect].
