2-1-2. Media Feed Mechanism
The major components of the media feed mechanism are:
(a) Unit, Motor
(d) Motor Drive Belt
(b) SA1, Drive Shaft
(e) Platen Drive Belt
(c) Unit, Roller Platen
(f) Tension Plate block
By setting the head block to the down position, the Unit, Head pushes media against the platen.
As the Unit, Motor (stepping motor) (located on the left) turns counterclockwise viewing from the
right side of the printer, the platen turns counterclockwise via the Motor Drive Belt (on the left side),
SA 1, Drive Shaft (that links left and right side) and Platen Drive Belt (on the right side). Then,
media is fed forward by the friction force produced between the platen and the Unit, Head.
Since the spring pulls the bottom of the Tension Plate block as shown in the figure, the Tension
Plate block gives an adequate tension to the Platen Drive Belt.
When the Unit, Motor turns clockwise viewing from the right side of the printer, media is fed
reversely.
One step of the Unit, Motor feeds media by 1/16 mm (0.0025").
