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.
