On this machine, ink affixed on the surface of the print heads might be hardened by ink mist (ink splashing during printing). If ink affixed on the surface of the print heads is hardened, dot drop-outs may occur. Continued use of the product in this state may cause a failure that requires the replacement of the print heads.
While daily cleaning is important to prevent dot drop-outs, there are also three important points to check before printing.
1. Shorten the distance to the print heads.
As the distance between the print heads () and the surface of the object to be printed on () increases, the likelihood of ink mist increases. When setting the height of the object to be printed on manually, make the distance as short as possible. When the height () is automatically set, the distance is about 1 mm (39.4 mil).
As the distance between the object to be printed on and the print heads increases, the likelihood of ink mist increases. Therefore, a jig might be required according to the size and shape of the object to be printed on. Prepare a jig if one of the following conditions is met.
With just the object to be printed on, no margins can be obtained in the areas 40 mm (1.57 in.) to both the right and left of the portion (width) of the data to be printed.

The variation in height of the surface of the object to be printed on is 2 mm (78.7 mil) or more.
