Bar-code Specifications
Mcl Bar-code Reader
Sample misidentification can occur from the use of incorrect, poor quality, damaged, dirty or
improperly placed bar-code labels. Follow the specifications in this section to create your bar-code
labels to prevent incorrect sample identification. See also

The instrument supports preprinted labels.
Bar-Code Label Optical Characteristics at 670 nm ±10%
•
Print Contrast Signal (PCS): 80% minimum.
•
Reflectivity of Media (RW): 80% minimum.
•
Reflectivity of Ink (RB): 16% maximum.
•
No spots or voids; no ink smearing.
•
Edge roughness is included in the bar and space tolerances.
Mcl Bar-code Reader
The MCL uses a visible-laser type reader containing a Class II laser, operating at 670 nm, with a
maximum power output of 1 mW.
Bar-code Decoder
The MCL sends a “GS” ASCII character (hexadecimal 1D) to the decoder to start operation.
