Printhead Pressure Alignment Adjust
The printer is factory-adjusted for full size media width. When
using media with less than full width, it is recommended to adjust
the printhead lift arm so it becomes centered on the media. Thereby,
an even pressure across the media is obtained.
A poorly adjusted lift arm may be detected by a weaker printout
on the inner part of a less than full width media. Similarly, when
reverting to wider media, the arm should be adjusted, or the print-
out on the outer part of the media could be weak.
To adjust the printhead lift arm, proceed as follows:
• Raise the printhead by turning the printhead lift lever to "Open"
position.
• Remove the ribbon, if any.
• Loosen the knob that holds the lift arm. Move the arm inwards
or outwards until the arrow on the tip of the arm becomes cen-
ter-aligned with the media.
If the arm is hard to move, pull the printhead bracket free from
the magnet in the lift arm. Pull down the arm to a position
between raised and lowered. Push at the inner part of the arm,
where the locking knob is situated.
• After having centered the arm, lock it by tightening the knob.
• Reload the ribbon, if any.
