When the printhead lift lever is turned from raised to lowered position,
the operator has to overcome a slight pressure from the coil spring until
the lever passes a vertical position. Then the printhead snaps into place
and the spiral spring applies its pressure. In the fi nal part of the movement,
the angular plate is rotated into the gap of the headlift sensor indicating a
“printhead closed” condition.
This exploded view shows the parts of the headlift mechanism. Also refer
to illustrations in Chapter 7.1 for assembled views.

The illustration shows an EasyCoder PF4i. All parts of the headlift
mechanism on the electronic compartment side of the center section and
the fi ne-adjustment screw are the same in all EasyCoder PF2/4i-series
printers. The transfer ribbon mechanism have been omitted to improve
visibility.
