Paper Paths and Components

Star-wheel Spring

It is a coil spring type loaded transversely. The objective is that the spring force is high

enough to eject all the media supported and is low enough not to produce any star-wheel

track marks or minimum marks within the acceptable level.

Spring force (@ span 14.2 mm and deflection 1.5 mm) : 19 gm

Deflection in assembled condition : 1.5 mm

Allows additional deflection to accommodate paper thickness : 1.2 mm

and other unusual operation (example: paper jam removal)

Output Mechanism

Output Ramps

Four sets of ramps are used to support different media from Post Cards to Super B-size

media during printing . This creates a bow-shape especially for media sizes B5,A,

Letter, Legal by stressing the media thereby increasing the drying time to avoid smearing

on the previous printed media.

Ramp Profile

The ramp has a slope in two stages with respect to horizontal or paper axis to increase

the resistance gradually.

stage angle :21°

stage angle :30°

Ramp also has slope in front direction which helps media to form bow-shape. Ramp

edges have been curved to reduce friction with mating platen surface.
