Cleaning the print head and roller
A blank horizontal line appearing through the printed label indicates that the print head and roller are
dirty. Clean the print head and roller according to the following procedure.
Print head
4 Use a dry cotton swab to gently wipe up and
down along the print head and roller.
Caution:
Be careful not to touch the cutter near the
print head and roller while cleaning them.
In addition, do not try to clean the
print head immediately after printing,
otherwise you may be burned.
5 Insert the tape cassette, and then close the
tape compartment cover.
* Cleaning can easily be done using the
optional print head cleaning cassette
(TZ-CL4).

Cleaning the tape cutter
After a while, adhesive may accumulate on the
cutter, preventing it from cutting or resulting in the
tape being jammed. Once a year, use a cotton swab
dipped in isopropyl (rubbing) alcohol to clean off
the cutter.
Do not touch the cutter’s edge, otherwise
you may be injured.
