The light printing of the black in the barcodes is caused by the angle of the printhead being to small. Note that the barcode darkens to normal as the print approaches the center of the card. Increasing the printthead angle will darken the beginning of the barcode. After adjusting the angle of the printhead it may be necessary to raise the Ribbon Peel-Off Bar.
Please consult with the ID card intergrator technical support area where you purchased your printer to obtain assistance for your specific printer issue prior to adjustment. For information about the Fargo DTC550 and current Fargo printers, contact our ID Card experts at 888-485-4696.
