5.10 Supporting bar (ribbon save)
Figure 23
If the transfer ribbon save function is active and a paper jam occurs or
if the print position onto the label is incorrect, this could be traced back
to an inadequate adjustment of the supporting bar (A).
The supporting bar (A) in connection with the beneath positioned
transport roller is responsible for the label feed (if printhead is lifted
up). The pressure of the supporting bar should be the same as the
value for the printhead. The factory setting corresponds to an average
for standard labels. For very narrow, extremely smooth or thick labels
a different setting is necessary.
Use the threaded pins (B) to change the pressure.
Pressure increase
= screw threaded pins (B).
Pressure decrease
= loosen threaded pins (B).
By means of test prints you can adjust the specific pressure you need
for your application.
