Image transfer device calibration label and method of making and using same

A method of fixing a calibration label to a scanner plate for installation in a scanner bezel, the bezel having a plurality of datuming points for locating a glass plate within the bezel, comprising the steps of:

• providing an assembly having a base, a first plurality of springs attached to said base for holding said glass plate away from said base, a plurality of datuming points wherein each one of said plurality of datuming points is fixed to said base and having a relationship to said base identical to the relationship a corresponding datum point has to the bezel, a second plurality of springs for biasing said glass plate against each one of said plurality of assembly datuming points and a trough for releasably holding a calibration label;
• placing an adhesive backed calibration label in said trough;
• positioning said glass plate between said second plurality of springs and said datuming points so that each one of said plurality of datuming points contacts an edge of said plate;
• urging said plate toward the assembly base to effect adhesion between said calibration label and said plate;
• and
• releasing said plate, including said calibration label, from said assembly.
