Troubleshooting

Inappropriate Paper Thickness Lever 
setting.

Adjust the position of the Paper Thickness Lever according to the type of paper 
you are printing on. See “Paper Handling” on page 5.
Depending on the printing content, the printing surface may become scratched 
even for the types of paper to set the lever to the left. In this case, set the Paper 
Thickness Lever to the right.
* Reset the Paper Thickness Lever to the left when you finish printing. If the 
lever is not set back to the left, the inside of the printer is more likely to get dirty 
due to the wider clearance between the print head and the loaded paper. It may 
also reduce print quality.

If the corners or edges of the paper are smudged, try to print with the Paper 
Thickness Lever set to the right.
