Pressing Roll Description

The pressing roller assembly presses the media towards the rear 
drive roller. The roller shaft is attached to a turning sleeve by means 
of two spring-loaded arms in order to be self-aligning. 

A linkage connects the turning sleeve to the headlift shaft so the 
pressing roller is lifted when the printed is lifted manually using 
the headlift knob (for example at media load), but not when the 
printhead is lifted by the headlift motor during ribbon save opera-
tion.
