Preventing Soiling of the Media, Dot Drop-out, and Dot Displacement

Removing the ink buildup on the print head surface before or during printing prevents soiling of the media, dot drop-out, and dot displacement.

In the following cases, ink tends to collect on the surface of the print heads.

  • When you use media prone to static electricity buildup.
  • When the ambient temperature is low.
  • When the print-head height is set to High.

    Periodically (Job Priority)Automatic cleaning is performed when the cumulative printing time reaches the value you set here.

Because printing is not paused, uneven color issues due to paused operation do not occur.
