settings first. For details, refer to the On-screen Manual.
zCheck 1: Confirm that the paper size setting matches the loaded paper size and that the
loaded paper is plain paper.
When the paper size setting is incorrect or other than plain paper is loaded, you cannot obtain a
proper print result. Also, the printed surface may be scratched.

quality setting and try printing again.
zCheck 3: If the problem is not resolved, there may be other causes.
