With good images on the display but not on the printer, one should:

• A. Increase the Gain
• B. Check the Scan Converter
• C. Check the Scan Head
• D. Adjust the Recorder

Answer: (D)

When the image looks correct on the display but doesn’t print correctly, the issue is in the output path to the printer rather than in how the image was formed. The display is already showing the proper signal, so changing the gain or the way the scan data are mapped to shades won’t fix the printer output. The scanner head and scan converter affect what you see on the monitor, not what the printer receives. The device that handles sending the image to the printer is the recorder, so adjusting the recorder’s output settings or calibration is the correct step to obtain a printer image that matches what’s on the screen.
