Do the print heads come into contact with the media?
The height of the print heads may be too low. Also, if the media is not loaded and set up correctly, it may wrinkle
or come loose and contact the print heads.

Are the print heads dirty?
The following may cause ink to drip on the media during prinng.
• Buildup of brous dust (lint) around the heads
• Ink transferred to the heads due to rubbing against the media
If this happens, clean the print heads manually. We recommend carrying out periodic head cleaning.
• Too low humidity
Use the machine in an environment with a humidity of 35 to 80%RH (no condensaon).
