The printed label contains blank horizontal lines.
A horizontal line can be a result of some dust or dirt attached to the surface of the print head.
Clean the print head as follows:
- Always disconnect the AC adapter and remove the batteries before cleaning the P-touch.
- Do not touch the print head directly with your bare hands.
- Turn off the P-touch.
- Disconnect the AC adapter and remove the batteries.
- Remove the tape cassette.
Gently wipe the print head up and down using a dry cotton swab.
The print head can be cleaned more easily with the optional print head cleaning cassette (TZe-CL4).
