Replacing the imaging guides Lamps (LEDs) Camera calibration Replace the imaging guides when they become damaged or heavily scratched. 1. Open the transport cover. 2. Gently pull the 2 fastening clips that secure the top imaging guide towards the front of the scanner to release and remove the imaging guide from the transport. 3. Install the new imaging guide into the scanner by holding the frame of the imaging guide so that the fastening clips are on the back side of the imaging guide. Slide the guides under the transport tray towards the feeder table and ease the back side of the imaging guide into position. 4. Repeat Steps 2 and 3 to replace the bottom imaging guide. 5. Close the transport cover. IMPORTANT: The LEDs on Ngenuity Scanners should NOT be cleaned or wiped with any type of wipes and/or solvent. The LED illumination system on Ngenuity Scanners should last the life of the scanner with normal use. If something happens that requires the replacement of the LEDs, contact Kodak Technical Support. Before calibrating, clean the scanner optics to ensure a successful calibration. See the section entitled, "Cleaning the optics" earlier in this chapter. Camera calibration is important for maintaining consistent image quality. Calibrating the cameras resets the white level and balance and the black level and balance in the scanner. It performs red, green, blue (RGB) color balance and gain setting, and horizontal light level correction. The final measurement results in a correction function which levels the brightness over the complete scan width. It is recommended that you calibrate the cameras together, although they can be calibrated independently. Calibration of both cameras takes approximately 4-7 minutes. NOTE: Before calibrating the camera(s), make sure full power is applied to the scanner (not in Sleep mode) for at least 5 minutes. 1. Open the Ngenuity Operator Utility and establish communication with the scanner. A-61662 April 2010 5-15
