Is the height of the print heads too low?

If the media jams, set the print heads to the "HIGH" position. Media may inevitably warp or wrinkle slight-
ly, so adjust the height of the print heads to take this into account.

Are the media clamps attached?

When you are performing printing with the head height set to "HIGH" or "LOW", be sure to attach the me-
dia clamps.

Is the media loaded and set up straight and securely?

Feeding is not smooth when the media is not straight or is tensioned unevenly on the left and right. Reload
the media.
