Perform this adjustment when UI PWB or the Control Panel are replaced. AdjustmentNOTE: Use the touch pen for the adjustment as it is installed in the UI Control Panel of the machine. A tapered substitute can be replaced if the pen has been lost. In this case, care should be taken not to have the UI surface scratched. 1. Switch off the power and remove the Control Panel Cover. 2. Remove the Touch Pen (Figure 1). Figure 1 Accessing the Touch Pen 3. Switch on the power while simultaneously holding down the numerical keys 0, 1, and 3 on the Control Panel. Calibration Screen 1 will be displayed (Figure 2). Figure 2 Calibration Screen 1 4. In numeric sequence (P 1 to P 9), touch the intersections of the vertical and horizontal lines with the touch pen. A message is displayed on the screen after each touch. After pressing down all the buttons, the machine will calculate the deviation and the cor- rection value on the coordinates. This automatic calculation takes about 0.1 second. 5. Calibration Screen 2 will be displayed (Figure 3). 6. Apply the adjusting pen to each of the four line intersections. A black square should appear at the point of contact, and a beep should sound. ï If four beeps are heard, adjustment is OK. ï If you donít hear four beeps, repeat the adjustment from step 3. Figure 3 Adjustment Screen #2 7. Switch off the power. Restore the pen to its original place and reinstall the Control Panel Cover.

6/02 4-184DC1632/2240 ADJ 9.14 Prelaunch Training/Review Repairs and AdjustmentsReference Information The correct light quantity value in ROS is normally 1024. If the value is decreased by 5%, the light quantity decreases too. Hence, entering the 5 stages of light quantity correction value by 5% is possible as below. 1024: Correct ROS Light Quantity Value 973: Light quantity value of 5% down 922: Light quantity value of 10% down 870: Light quantity value of 15% down 919: Light quantity value of 20% down 5. Take test patterns again with the Step 2 mode after changing. 6. Repeat Steps 3~5 until the density distribution that the client requests can be obtained. 7. Check the condition using the customers samples. (Or ask the customer to print out the sample from the same file and check the density on it.) NOTE: Be careful in servicing because tone jump trouble may occur if the adjustment is cor- rected drastically. The tone jump is a noticeable difference in the midstream of gradations when the gradations etc. are printed out. NOTE: When copying, borrow the document or sample that the clients has complained about.
