Problem What to Do
1. The display stays blank after you
have turned on the machine.
Check the polarity of the batteries.
If the batteries are low, replace
them.
Check that the adaptor is working
properly.
2. The machine does not print, or the
printed characters are blurred.
Check that the tape cassette has
been inserted properly.
If the tape cassette is empty, re-
place it with a new one.
Check that the character size is
appropriate for the width of the
tape that is used.
3. The printed characters are not
formed properly.
The batteries are probably weak.
Replace them.
4. The tape cannot be cut. The cutting blade is probably dull.
Replace the cutter unit.
5. Striped tape appears. You have reached the end of the
tape. Replace it with a new tape.
6. The memory has cleared on its
own.
The batteries are probably weak.
Replace them.
7. An unprinted line appears on a
label.
There may be some dust on the
print head. Wipe the print head
gently with a dry cotton swab.
If dust still remains, dip the cotton
swab in isopropyl (rubbing) alco-
hol and wipe the print head again.
