Printhead Dot Line Position
When using thick or stiff media, the printhead needs to be moved forward
so the dot line becomes exactly aligned with the top of the platen roller.
Obviously, the platen roller and printhead must also be completely in
parallel.
To perform this adjustment, follow all the steps below:
1 Open the top cover.
2 Remove the ribbon.
3 Important step! Use a straight-slot screwdriver to turn the two screws at
the top of the printhead bracket counterclockwise a single turn.
