CP-S317 CP-X327

4-6 Color uniformity adjustment

Preparations

1. Perform these adjustments after the white balance

adjustment described in Section 4-5.

2. Make a color uniformity adjustment for the

following four tones.

MIN tone (approx. 4% input signal)

MID-L tone (approx. 14% input signal)

MID-H tone (approx. 25% input signal)

MAX tone (approx. 57% input signal)

3. Place the cursor on the tone to be adjusted in the

Adjust menu and press the [ ] key. This displays

the Adjust Tone menu at the bottom of the screen.

Select the major adjustment lattice point No. and

color, and then adjust them.

4. The major adjustment lattice point numbers (a total

of 17 points) corresponds to the major adjustment

lattice point positions in the diagram on the right.

The color uniformity of the entire screen can be

adjusted by adjusting the white balance for each of

the points starting in order from the low numbers.

5. Adjustment point No.1 should not be adjusted,

because it controls the brightness of the entire

screen.

6. To temporarily turn correction off, place the cursor

on “ON” in the Adjust Tone menu and press the [ ]

key. To turn it on again, place the cursor on OFF in

the Adjust Tone menu and press the [ ] key.

Adjustment procedure 1

(when a color differential meter is used)

1. First adjust [MID-L] tone [G:].

2. Select adjustment point [No.2][G:].

When the background is not [G] monochrome,

press the [MENU SELECT] key on the Remote

control transmitter to change to solid [G]

monochrome.

3. Measure the illumination at adjustment points No.

2, No.3, No.10 and No.11.

The values should be:

No.2 = Y2 [lx] No.10 = Y10 [lx]

No.3 = Y3 [lx] No.11 = Y11 [lx]

4. No.2 and No.3 adjustment point have the average

of Y2 and Y3.

Y2 = ( Y2 + Y3 ) / 2 ± 2 [%]

Y3 = ( Y2 + Y3 ) / 2 ± 2 [%]

5. No.10 and No.11 adjustment point have the

average of Y10 and Y11.

Y10 = ( Y10 + Y11 ) / 2 ± 2 [%]

Y11 = ( Y10 + Y11 ) / 2 ± 2 [%]

6. Then adjust [MID-L] tone [R] and [B].

When the background is [G] monochrome, press

the [MENU SELECT] key on the Remote control

transmitter to change to solid white.

7. Measure the color coordinates of adjustment point

[No.1] and make a note of them.

Assume that they are x = x1, y = y1.

Note: When the CL-100 color and color difference

meter is used, the [

convenient. When adjustment point [No.1]

color coordinate has been selected, set the

slide switch on the side to [ ](delta) while

holding down the [F] button on the front

panel. The measurement shown after this

displays the deviation from measurement

point 1.

8. Measure the color coordinates of measurement

point [No.2] and adjust [No.2][R:] and [B:] so that

the coordinates are as follows.

x = x1 ± 0.005 , y = y1 ± 0.010

](delta) mode is

CP-S317 CP-X327

9. Similarly, measure adjustment points [No.3] to

[No.17] and adjust their color coordinates starting

in order from the small number points.

This completes adjustments required for [MIN].

Note: Since excessive correction may lead to a

correction data overview during internal

calculations, use the following values for

reference.

[No.2] to [No.5] ± 40 or less

[No.6] to [No.9] ± 50 or less

[No.10] to [No.13] ± 70 or less

[No.14] to [No.17] ± 120 or less

10. Then adjust [MIN] tone [G] so that the adjustment

data set two times as much as [MID-L] tone [G].

This completes [G] color adjustments.

11. Then adjust [MIN] tone [R] and [B].

Select [No.2] [B:] and press the [MENU SELECT]

key on the Remote control transmitter to change to

solid white.

12. Measure the color coordinates of adjustment point

[No.1] and make a note of them.

Assume that they are x = x1, y = y1.

13. Now measure the color coordinates of

measurement point [No.2] and adjust [No.2][R:]

and [B:] so that the coordinates are as follows.

x = x1 ± 0.005 , y = y1 ± 0.010 (Target)

x = x1 ± 0.020 , y = y1 ± 0.040

14. Similarly, measure adjustment points [No.3] to

[No.17] and adjust their color coordinates starting

in order from the small number points.

This completes [MIN] tone adjustments.

15. Now make similar adjustments for [MID-H] tone.

(Adjust [MID-H] tone [G] so that the adjustment

data set half as many as [MID-L] tone [G].)

16. Now make similar adjustments for [MAX] tone.

(Adjust [MAX] tone [G] so that the adjustment data

set half as many as [MID-L] tone [G].)

CP-S317 CP-X327

Adjustment procedure 2

(visual inspection)

1. First adjust [MIN] tone [G:].

2. Select [No.2] [G:].

If the background is [G] monochrome, press the

[MENU SELECT] key on the Remote control

transmitter to change to solid white.

3. View measurement point [No.2] and [No.3].

Lower the [G] color intensity only of the color point

whose [G] color is more intense than measurement

point [No.1].

4. View measurement point [No.10] and [No.11].

Lower the [G] color intensity only of the color point

whose [G] color is more intense than measurement

point [No.1], and raise the intensity of the point

whose color intensity is lower than measurement

point [No.1].

5. Now adjust the [MIN] tone for colors [R] and [B].

6. View measurement points [No.2], [No.3], [No.10]

and [No.11]. Adjust the [R] and [B] of each

measurement point so that they have the same

color as measurement point [No.1].

Adjustment technique:

First, adjust [B:] of the point whose color is to be

adjusted so that it approximates that of [No.1]. If

[R:] is low at this time, the image will have cyan

cast, in which case [R:] is increased. On the other

hand, if [R:] is excessive, the image will have a

magenta cast, in which case [R:] is decreased.

Overall, a cyan cast makes it easy to see color shading.

7. Next, view measurement points [No.4], [No.5],

[No.12], [No.13] and make similar adjustments.

Then adjust measurement points [No.6], [No.7], [No.8],

[No.9], [No.14], [No.15], [No.16] and [No.17].

This completes the [MIN] tone adjustments.

9. Make similar another three tones as described in

steps 1 to 8 above.

Caring for the air filter

HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE

Before replacing the lamp, check the serial number of the replacement lamp bulb (sold separately: DT00511 for CP-S317/DT00521 for CP-X327), then contact your local dealer. Before replacing the lamp, turn off the power, and unplug the power cord, then wait at least 45 minutes, in order to ensure that the lamp is properly cooled. Removing the lamp bulb while it is still hot could cause burns, or cause the lamp bulb to burst.

The LCD projector uses a glass lamp bulb. It is a mercury lamp with high

internal pressure. High-pressure mercury lamps can break with a loud bang, or burn out, if jolted or scratched, or through wear over time. Each lamp has a different lifetime, and some may burst or burn out soon after you start using them. In addition, when the bulb bursts, it is possible for shards of glass to fly into the lamp housing, and for gas containing mercury to escape from the projector’s vent holes.

•

Handle with care: jolting or scratching could cause the lamp bulb to burst during use.

•

If the replace lamp indicator (see "Related Messages" and "Regarding the indicator Lamps") comes on, replace the lamp as soon as possible. Using the lamp for long periods of time, or past the replacement date, could cause it to burst. Do not use old (used) lamps; this is a cause of breakage.

•

If the lamp breaks soon after the first time it is used, it is possible that there are electrical problems elsewhere besides the lamp. If this happens, contact your local dealer.

•

If the lamp should break (it will make a loud bang when it does), ventilate the room well, and make sure not to breathe the gas that comes out of the projector vents, or get it in your eyes or mouth.

•

If the lamp should break (it will make a loud bang when it does), unplug the power cord from the outlet, and make sure to request a replacement lamp from your local dealer. Note that shards of glass could damage the projector’s internals, or cause injury during handling, so please do not try to clean the projector or replace the lamp yourself.

•

Obey local ordinances when disposing of used lamps. In most cases, it is possible to dispose of used bulbs in the same manner as used glass bottles, but in some cases, bulbs are sorted separately.

• Do not use the projector with the lamp cover removed.

WARNING

The air filter should be cleaned about every 100 hours. If the LAMP indicator and TEMP indicator blink red simultaneously, or a message prompts you to clean the air filter when you turn on the unit, the filter needs to be cleaned. (See "Related Messages" and "Regarding the Indicator Lamps" for details.)

Turn off the projector, and unplug the power cord

Apply a vacuum cleaner to the top of the air filter cover to clean the air filter

Turn on the projector, and use the menu to reset the filter timer
