2.2 Media Width Adjustment To prevent wear on the Printhead and Platen, adjust the printer when using media that is less than four inches (102 mm) wide, as follows: 1. Load media. Print a batch of labels. (Simultaneously press F2 and F3, or send a format from the host.) While facing the front of the printer Turning the Thumbwheel clockwise increases the effect. Turning the Thumbwheel counterclockwise decreases the effect. Note: The Thumbwheel is numbered for reference, where zero is the lowest setting and nine is the highest. 2. While the labels print, adjust the Thumbwheel until the image begins to fade. Over-adjustment produces an image that fades across the label. 3. Then turn the Thumbwheel in the opposite direction until the full image is produced. Correct adjustment produces a complete image, with even print contrast across the label. Note: Under-adjustment can cause ribbon wrinkling and excessive wear on the Printhead and Platen. If the media moves excessively rightward while printing, the Thumbwheel should be adjusted clockwise. 2-6 Maintenance and Adjustments
2.3 Ribbon Width Adjustment If equipped with the thermal transfer option, the Ribbon Tension Adjustment Knob allows the optimum amount tension to be applied to the ribbon, as follows: 1. Turn OFF the printer. Remove ribbon, if installed. 2. While holding the Hub, rotate the Ribbon Tension Adjustment Knob to match the ribbon width, according on the table below. Ribbon Width Direction of Rotation 1-2 inches (25 51 mm) Clockwise 2-4 inches (50 102 mm) Counterclockwise 3. Ensure that the Ribbon Tension Adjustment Knob is turned fully into position and will no longer rotate. Note: Never force or over-tighten the Ribbon Tension Adjustment Knob. 2.4 Printhead Adjustment If necessary, print quality can be mechanically adjusted. Although factory set for optimum print quality, some media types (for example, heavy card stock) may require a slight readjustment if quality changes. 1. Load media. Print a batch of labels. (Simultaneously press F2 and F3, or send a format from the host.) Maintenance and Adjustments 2-7
2. While the labels print, turn the Printhead Adjustment Screw until optimum print quality is obtained.
