Occasionally, specks of dust or dirt become attached to the machine’s print head and rollers.
This is particularly likely when you are using the unit outdoors or in a very dusty environment.
If a section of the print head is covered with dust, a white horizontal streak may appear
through the label text. Therefore, as with a tape recorder, the machine’s head may need to be
cleaned from time to time.
To clean the print head and rollers:
1 Turn off the machine.
2 Open the tape compartment cover, and then remove the tape cassette if one is installed.
The print head and rollers are located in the tape compartment.
3 Print head: Use a dry cotton swab to gently wipe the print head with an up-and-down
motion.
Rollers: Use a dry cotton swab to wipe each roller with an up-and-down motion while
rotating them with your finger.
4 Install a tape cassette, close the tape compartment cover, and then try printing again.
5 If a white streak still appears in the label, repeat steps 3 and 4 using a cotton swab
dipped in isopropyl (rubbing) alcohol.
If none of the above works, contact your service representative.
☞ The print head can be cleaned more easily if the optional print head cleaning cassette
(TZ-CL4) is used.
