ADJ 9.13  UI Display CalibrationPurposeAdjust the display by making the buttons on the display correspond to the Touch Panel, so that
users can correctly select the content indicated on the display.
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.

ADJ 9.14 Inboard/Outboard DensityPurposeTo perform the ROS In/Out light quantity correction with this adjustment, when IN/Out densities
are different but the parameters other than ROS light quantity judges that all is normal. Adjustment1. Enter dC612.
2. Select the Test Pattern in the modes as shown below and print out the test pattern.
ï Pattern name: Binary highlight PG LUT: C-TRA On IOT ON 
(Pattern No 13??? 25?)
ï Color Mode: 4C
ï Cin (%): 20%
ï Number of prints: 1

3. Select the pattern that has the same inclination on the four check points in the test pattern
from the 20 patterns below.
Write down the Pattern number.  (Vertical axis shows density, and horizontal axis shows
width direction in the pattern)

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.
