Laser Power

1.5 mW typical, 

λ = 650 nm nominal

Scan Rate

104 (±12) scans/sec (bidirectional) 

Print Contrast

Minimum 25% absolute dark/light reflectance measured at 650 nm.

Default (Wide): 47° ± 3°

Alternate (Narrow): 35° ± 3°

Note: The Symbol MS954 does not require margin on either side of the bar code to 
decode. The 47° scan line provides identical scanning performance to older 
minscans (e.g., Symbol MS923) with a scan line of 53°.
