Dots within characters are
missing 1. Check whether the ribbon is damaged. To do so check the rib-
bon cassettes functionality by turning the green tension gear in
direction of the arrow on the cassette; check if the ribbon itself
is torn or has holes etc. If necessary replace the ribbon cas-
sette; see the chapter
Changing the ribbon cassette , page 35.
2. Check whether the print head is damaged. To do so print out a
status page (see
Printing out the status page , page 55) and
check if under the lines representing the software versions all
24 lines are present. Every line represents one of the 24 nee-
dles of the print head. If not so, replace the print head; see the
chapter
Replacing the print head , page 41.
We recommend to use genuine ribbon cassettes only.
In case of a damaged print head, please contact your
dealer.
