Adjusting the Forms Thickness Setting To adjust the lightness or darkness of the print, you must increase or decrease the gap between the print head and the platen rod. This distance is automatically set for you by the Automatic Forms Thickness Adjustment (AFTA), but you can make corrections to the distance if the print output is not as you desire. It is up to you to decide if the print is dark (or light) enough to meet your requirements. To adjust the forms thickness setting with the F3 forms device, follow these steps: 1. The forms thickness setting must be adjusted when the printer is printing or has printed and is ready. Press Start, if needed, to have the printer display READY 2. To make the print darker, press Darker. The printer displays LIGHT | -------| DARK The print head moves closer to the paper, and the print becomes darker. Note: The print may not get darker if the ribbon is worn or if there is a problem with the print head. 3. To make the print lighter, press Lighter. The printer displays LIGHT | DARK The print head moves farther away from the paper, and the print becomes lighter. 1-102 User's Guide
