1. COMPLIANCE OF SAFE REPAIR
Be sure to read this Service Manual before providing services. In the PLUS Copyboard, full consideration is
taken to ensure the safety for a fire, electric shock, injury, harmful radiation, and substance. Therefore, observe
the notice described in this Service Manual so that the safety is kept when providing services. Moreover, be sure
to observe the notice described in the Instruction Manual.
Pay attention to the following during service inspection.
1-1. Cautions during Product Movement
• It is necessary to remove the products when making the service of products put on the wall. At that time, hold
the products by two or more persons to prevent the products from dropping or a person from falling down.
1-2. Cautions during disassembling and assembling
1. This equipment contains parts under high voltage. When doing repairs, make sure that power plug is pulled
out to insure safety.
2. Make sure that parts and screws and wiring, etc. are returned to their original positions. Tube, tape and
other insulation materials have been used for safety reasons. The internal wiring has been designed to
avoid direct contact with hot parts or parts under high voltage when using clamps or other tools.
3. The parts used in this device have special safety features such as flame-resistance and anti-voltage proper-
ties. When replacing parts, always use parts supplied from the factory.
4. After finishing operations make sure that all parts and wires have been returned to their original position and
that there has been no deterioration of the area around the location that was worked on.
5. Be sure to use an earth band (wrist band) during repair and inspection.

5. ADJUSTMENT
5-1. CCD Unit Adjustment
Adjustment is required in the following case. (Calibration is also required. See 5-2. Calibration method.)
•When a CCD Unit is replaced
•When adjustment gets out of order due to the failure during shipping (shock during transportation such as
vibration)
•Severest deterioration in picture quality (The picture quality may not be improved.)
Preparation
•Oscilloscope
•Phillips screwdriver No. 2
•Screwdriver for ceramic adjustment (2mm wide)
•Allen wrench (Across flat has 1.5 mm)
Turn ON the power to an oscilloscope. Clean the plate surface sufficiently.
* Insufficient cleaning may influence the subsequent calibration and cause sometimes irregular color.
CCD Unit adjustment procedure
1) Remove the Back Panel.
2) Connect an oscilloscope to the CCD Unit (CCD board).
(See the figure on the right.)
•Connect GND in Ch2 (Ext TRG) to J4.
•Connect the measurement pin in Ch2 to J3 (TRG).
•Connect GND in Ch1 to J1.
•Connect the measurement pin in Ch1 to J2.
3) Setting of oscilloscope
•Set the Ch1 mode to 2 V/DIV AC.
•Set the Ch2 (Ext TRG) mode to 1 V/DIV DC.
•Set the sweep to 500 Ésec/DIV.
•Set the trigger to EXT or Ch2.
•Only Ch1 is displayed.

ADJUSTMENT
4) Focus adjustment screw of lens unit (See Figure 1.)
Fix screw A temporarily so that the distance between the lens unit and holder is 1.7 mm.
5) Write test patterns on the sheet surface. (See Figures 2 and 3.)
(Clean the plate surface sufficiently. If not, the subsequent calibration cannot be performed correctly.)
As shown in Figure 2, write test patterns on the plate surface using a black marker.
•Write horizontal lines of 68 mm (two ruled lines) in the upper, middle, and lower positions according to the
ruled line.
•Write vertical lines in the upper, middle, and lower positions, 68 mm (two ruled lines) away from the
horizontal lines, according to the ruled line.
(In only the middle position, the vertical line is 68 mm (two ruled lines). In the upper and lower positions,
the vertical lines are 34 mm (one ruled line).
Notes: Write them so that the horizontal lines in the upper and lower positions are put in the ruled lines as
shown in Figure 3.

ADJUSTMENT
6) Put the set into the adjustment mode.
•Turn ON the power.
•Insert CF in which a command in the adjustment mode was put.
The set is put into the CCD adjustment mode, so confirm that CCFL lights.
7) Adjustment of oscilloscope (See Figures 4 and 5.)
•Adjust the trigger level, CH1 vertical position, Ch1 horizontal position, luminance, and focus so that a CCD
waveform appears on the oscilloscope. Also, adjust the trigger level in Ch2 (Ext TRG) and fix the wave-
form.
•Adjust VR on the CCD board so that the waveform is set to 4 Vp-p using a ceramic adjustment screwdriver.

•Move a sheet so that the test patterns (vertical lines) written in step 5) are displayed on an oscilloscope.
•Loosen screws D shown in Figure 10, move the CCD board, and fix screws D when the upper and lower
vertical lines equally go down as shown in Figure 11.
10) Focus adjustment (See Figures 12 and 13.)
•Loosen screw E shown in Figure 12, monitor the waveform on the oscilloscope displayed during adjust-
ment in step 9), and move the lens unit for focus adjustment so that the waveform becomes sharp as far as
possible.
•Fix screw E when the waveform becomes sharp as shown in Figure 13.
Notes: If the focus is insufficiently adjusted, an error may occur during calibration offset correction de-
scribed later.
