2-1-2. Media Feed Mechanism
The major components of the media feed mechanism are:
(a) SA PF Motor
(b) SA2_Platen
(c) Gear train
By setting the head block to the down position, media is pushed against the “SA2_Platen” by the
“SA, Head”.
As the “SA PF Motor” (stepping motor) turns counterclockwise viewing from the right side of the
printer, the “SA2_Platen” turns counterclockwise via the gear train (“Gear Reduction PF 1”, “Gear
Reduction PF 2” and “Gear Idle PF”) and media is fed forward by the friction force produced
between the “SA2_Platen” and the “SA, Head”.
When the “SA PF Motor” turns clockwise, media is fed backwards.
One step of the “SA PF Motor” feeds media by 1/16 mm (0.0025").
