11) When transporting a PWB, be sure to place the PWB in an anti-static bag.
It may cause a breakdown or malfunctions.
2. Warning for servicing
1) Be sure to connect the power cord only to a power outlet that meets the specified voltage and current requirements.
Avoid complex wiring, which may lead to a fire or an electric shock.
2) If there is any abnormality such as a smoke or an abnormal smell, interrupt the job and disconnect the power plug.
It may cause a fire or an electric shock.
3) Be sure to connect the grounding wire. If an electric leakage occurs without grounding, a fire or an electric shock may result.
For proper machine functionality, the machine must be grounded.
4) When connecting the grounding wire, never connect it to the following points.
It may cause an explosion, a fire or an electric shock.
- Gas tube
- Lightning conductor
- A water pipe or a water faucet, which is not recognized as a
grounding object by the authorities.
- Grounding wire for telephone line
5) Do not damage, break, or twist the power cord.
Do not put heavy objects on the power cable. Do not forcefully bend or pull the power cable.
It may cause a fire or an electric shock.
6) Keep the power cable away from a heat source.
Do not insert the power plug with dust on it into a power outlet.
It may cause a fire or an electric shock.
7) Do not put a metallic object or a container with water in it inside the machine.

*1: Life of each color A4 5% coverage30% color ratio conversion value
(The ratio is a rough reference since it differs depending on print contents, paper seizes, kinds of paper, use environment, the number of
continuous prints.)
3. Definition of developer/drum life end
When the developer/drum counter reaches the specified count.
When the developer/drum rpm reaches the specified count.
When either of the above reach the specified count, it is judged as life end.
In an actual case, the ratio of monochrome output and color output may differ greatly.
When data of mixed documents (monochrome and color) are output, monochrome document data may be output in the color mode in order to prevent against fall in the job efficiency. (ACS auto color selection).
In addition, when correction or warm-up operation is performed as well as output operation, the developer and the drum rotates.
Therefore, the developer/drum consuming level cannot be determined only by the copy/print quantity. When, therefore, the rpm reaches the specified amount, it is judged as life end.
To check the developer/drum life, use SIM22-01.

Fine adjustment pattern check:
Check the square frames on the R side and the F side of each color. (Normally five sections of high density can be seen.) Check the sub scanning direction position of the center area of high density (one of the above five sections). These must be on the same position on the R side and the F side.
In this case, use the sub scan direction color image shift check scale (fine adjustment) as the reference.
Visually check the color density and make the darkest section as the center, and use it as the read value of the shift amount.
Check that the difference in the center position of the dark den­sity section is within +/- 2 step.
The positional relations of the front and the rear frame of the print color patterns of a same color are compared. There is no need that all the colors are in the same state. Compare only the positional relations of color patterns of a same color.
If the above condition is not met, do the following:
11) Turn the image skew adjustment screw of the target color to
adjust. Relationship between the adjustment screw rotating angle and
the change in the adjustment image position: Adjustment screw rotating angle (degree) = Image shift
amount (Adjustment scale) x10
Repeat procedures 10) - 11) until a satisfactory result is obtained.

5-B Print engine image skew (LSU skew)
adjustment (Manual adjustment) (No need to adjust normally)
If a more accurate adjustment than the automatic adjustment ADJ 5A is required, use this method of adjustment.
This adjustment is made by changing the parallelism of the LSU unit scan laser beams for the OPC drum.
1) Enter the SIM 50-20 or 64-01 mode.
2) Select the paper feed tray with A4(11"x8.5") paper in it, and press [START] key.
3) The image skew (image registration) adjustment pattern is printed.
4) Check the printed black image for any skew. Use the four cross points printed in black to measure the
squareness. There are following two methods of checking the black image
for any skew (right angle).
Method 1
Measure the distances between opposing corners of the rect­angle print pattern, and compare the two distances to check the squareness.
Method 2
Check the squareness of the vertical and horizontal sides of the rectangle print pattern by using A4(11"x8.5") paper sides.
In the case of Method 2, the right angle of paper to be used may not be exact. Be sure to check the right angle of paper to be used in advance.
Method 1
Measure the length of the diagonal lines of the rectangle print pattern.
Calculate the difference between the measured lengths C and D of the diagonal lines.
Check to insure that the difference between C and D is in the following range.
C - D = 0.8mm If the difference between C and D is in the above range, there
is no need to adjust.
Method 2
Fit the side of A4(11"x8.5") paper to the long side of the rectan­gle print pattern.
Measure the slant (skew) of the vertical side for the horizontal side of paper as shown in the figure.
If the above distance is 0.5mm or less, there is no need to adjust.
If the above condition is not satisfied, perform the following procedure.
5) Open the front cover, remove the waste toner box, and turn the four LSU image skew adjustment screws in the same direction by the same amount.
For the adjustment, remove the front cover and the waste toner box, and turn the skew adjustment screw.
(Skew adjustment screw rotation direction)
When C is greater than D in the method 1 or there is some skew in the direction A in the method 2, turn the screw clock­wise.
When C is smaller than D in the method 1 or there is some skew in the direction B in the method 2, turn the screw coun­terclockwise.
(Reference of the rotation amount of the skew adjustment screw)
In case of the method 1, 0.8mm/about 1.5 rotations In case of the method 2, 0.5mm/about 1.5 rotations Repeat the procedures 2) to 6). After completion of the black image skew adjustment, go to the
procedure 7).
6) Perform the same procedures as 1) and 2).
7) Check the printed color image for any skew. If the difference between the shift amounts on the F and R
sides is within +/- 1 scale of the fine adjustment check scale, there is no need to perform the adjustment.
Measure the skew amount from the print patterns on the front and rear sides of each color.

MX-C250 ADJUSTMENTS 5 – 17
In each Y/M/C color print pattern printed separately in the F side and in the R side, note the same print color pattern and check to confirm that the F side and the R side look identical.
Rough adjustment pattern check:
Check the sub scan rough adjustment color image shift check section on the R side and the F side of each color, use the cen­ter position of the black scale as the reference, and check the balance in shifts of the color image line positions in the positive and the negative directions. The balance in the R side must be the same as that in the F side.
Fine adjustment pattern check:
Check the square frames on the R side and the F side of each color. (Normally five sections of high density can be seen.) Check the sub scanning direction position of the center area of high density (one of the above five sections). These must be on the same position on the R side and the F side.
In this case, use the sub scan direction color image shift check scale (fine adjustment) as the reference.
Visually check the color density and make the darkest section as the center, and use it as the read value of the shift amount.
Check that the difference in the center position of the dark den­sity section is within +/-1 step.
The positional relations of the front and the rear frame of the print color patterns of a same color are compared. There is no need that all the colors are in the same state. Compare only the positional relations of color patterns of a same color.
If the above condition is not satisfied, perform the following procedure.
8) Turn the LSU skew adjustment screw of the adjustment target color to adjust.
(Skew adjustment screw rotation direction)
When the F side is skewed to the right side for R side: Turn the screw clockwise.
When the F side is skewed to the left side for the R side: Turn the screw counterclockwise.
(Reference of the rotation amount of the skew adjustment screw)
Skew of difference by one step between F and R sides (Differ­ence by one scale of the fine adjustment check scale) / Turn for about 2 clicks.
Repeat the procedures 7) to 8) until a satisfactory result is obtained.
5-C Color registration offset adjustment
(No need to adjust normally)
This adjustment is used to set the offset value for the automatic color registration adjustment (ADJ 5A).
If there is any difference in color phase at the center and the four corners of an actual print image, this adjustment may improve it. Especially when there is any color shift at the center area, this adjustment may improve it effectively.
This adjustment cannot eliminate color shifts in all the areas, but average the overall color shifts.
After the automatic adjustment, use this color registration offset adjustment to correct color shift partially, performing the adjustment efficiently.
Before execution of this adjustment, check to confirm that the fol­lowing adjustment has been properly made.
* ADJ 5A or ADJ 5B image skew adjustment (LSU unit)
[Kinds of adjustment values]
There are following two kinds of registration adjustment values.
- Base registration adjustment value: XXX(FRONT)/XXX(REAR) They are manual adjustment values and automatic adjustment
values, and reflected when the automatic registration adjustment is executed. It varies for every operation of the automatic regis­tration adjustment.
- Offset adjustment values: OFFSETXXF/OFFSETXXR They are the offset adjustment values added to the above base
registration adjustment values, and are not changed unless SIM50-20 is executed to change.
1) Enter SIM50-20 mode.
2) Select the paper feed tray with A4(11"x8.5") paper in it.
3) Press [OK] key.
The color image registration check pattern is printed.
4) Check the color image registration.
There are 6 color image registration patterns in total; two on each of the F side, the R side, and the center. Check all the patterns to confirm that they are within the specified range. Also check to confirm that there is not much shift in each color image registration check pattern.
There are two kinds of adjustment: one in the main scanning direction and the other in the sub scanning direction. The verti­cal direction in the above figure is that in the main scanning direction, and the horizontal direction is that in the sub scan­ning direction.

MX-C250 ADJUSTMENTS 5 – 18
There are also two kinds of adjustments: the rough adjustment and the fine adjustment. Perform the rough adjustment then perform the fine adjustment.
For the main scan direction image registration, the offset on the F side, the R side, and at the center is independently adjusted.
If there is a difference in the sub scanning direction image registra­tion between the F and R sides, perform the skew adjustment (ADJ 5A).
Check the print patterns of the rough adjustment and the fine adjustment of 18 check patterns.
How to check the rough adjustment pattern and input of the adjustment value:
Visually check the color image registration check section, use the center position of the black scale as the reference, and check the shift balance in the positive and negative directions at the color image line position.
Use the center position of the black scale as the reference, and check that the color image line is symmetrical in the positive side and the negative side.
If shift is in the arrow mark X1 and Y1, increase the adjustment value. If shift is in the arrow mark X2 and Y2, decrease the adjust­ment value.
The reference arrow on the check pattern faces the positive direc­tion.
(Reference adjustment value)
1 scale/10 (When the set value is changed by 10, shift is made by 1 scale.)
How to check the fine adjustment pattern and input of the adjustment value:
Check to confirm that the darkest spot (one of 5 spots seen nor­mally) is within the center area of the image registration adjustment reference frame in the square frame.
At that time, use the color image registration check scale (fine adjustment) as the reference.
Visually check and consider the darkest section of color density as the center, and measure the shift from it.
Check to confirm that the center of the dark density section is within +/- 1 step.
(If the fine adjustment print pattern is in the range of 0 +/- 1 for the fine adjustment reference pattern scale, there is no need to adjust.)
If shift is in the arrow mark X1 and Y1, increase the adjustment value. If shift is in the arrow mark X2 and Y2, decrease the adjust­ment value.
(Reference adjustment value)
1 scale/1 (When the set value is changed by 1, shift is made by 1 scale.)
If there is a considerable difference in color shift in the square and at the center area, perform the adjustment.
Select an adjustment item (OFF SET X F / OFF SET X R / OFF SET X S), and change the adjustment value to adjust.
OFF SET X F: F side main scanning direction registration offset set value (The color shift on the F side and at the center area is changed.)
OFF SET X D: R side main scanning direction registration offset set value (The color shift on the R side and at the center area is changed.)
OFF SET X S: Sub scanning direction registration offset set value (Color is shifted to the sub scanning direction overall.)
When the adjustment value of OFF SET X F and OFF SET X R are changed, the color at the center area will be affected. Consider this when executing the adjustment.
(Adjustment conditions and method)
T o adjust evenly overall, adjust so that the color shifts on the F side, the R aide and at the center are of the same level.
To adjust with the center area most focused, adjust so that the color shift at the center becomes smaller than that on the F side and the R side.
When the offset adjustment value is 0, if the color registration adjustment (automatic adjustment) is performed, the color shift on the F side and that on the R side are automatically adjusted to be smaller than that on the center area.

a. Adjustment procedures
1) Place the duplex adjustment chart shown below on the docu­ment tray of the RSPF.
The adjustment chart is prepared by the following procedures. Use A4 (11" x 8.5") paper, and put marks on both sides and
both surfaces of the paper at 10mm from each edge.
2) Make a duplex copy at the normal ratio on A4 paper.
3) Measure the images on the copy paper and the original images.
4) Obtain the image magnification ratio according to the following formula:
Image magnification ratio = Original size / Original size x 100 (%)
Image magnification ratio = 99 / 100 x 100 = 99 (%) If the image magnification ratio is within the specified range
(100 +/-1.0%), there is no need to perform the adjustment. If it is not within the specified range, perform the following pro-
cedures.
5) Enter the SIM 48-1 mode.

(Though the following items affect the color balance/den sity, there is no need to adjust them frequently. When, however, a trouble occurs, they must be checked and adjusted.)
1) The following items must be adjusted properly.
Note for the color balance/density check and adjustments
- For the color balance adjustments, be sure to use the paper specified for color (recommended paper).
Note that, if another kind of paper is used for the color balance adjustment, proper image qualities (color balance, density) may not be obtained.
- When setting the adjustment pattern on the document table in the automatic color balance adjustment procedures, place 5 sheets of white paper on the adjustment pattern in order to pre­vent back copying and adverse effects of paper wrinkles as far as possible.
(2) Relationship between the servicing job contents and the
color balance/density check and adjustment
Note that the jobs before and after execution of the color balance/ density check and adjustment depend on the machine status and the servicing conditions.
Follow the flowchart of the color balance/density adjustment proce­dures depending on the actual conditions.
There are following four, major cases.
1) When installing
2) When a periodic maintenance is performed.
3) When a repair, an inspection, or a maintenance is performed.
(When a consumable part is replaced.)
4) When an installation, a repair, or inspection is performed.
(Without replacement of a consumable part)
(3) Copy color balance and density check
Before checking the copy color balance and density, be sure to execute the following jobs.
* Execute the high density image correction (Process correction)
forcibly. (SIM 44-6)
* Execute the half-tone image correction forcibly. (SIM 44-26)
Method 1
Make a copy of the gray test chart (UKOG-0162FCZZ) and a copy of the servicing color test chart (UKOG-0326FCZZ/UKOG­0326FC11), and check that they are proper.
a. Note for execution of the color balance and density check
in the color copy mode
To check the copy color balance and density, use the gray test chart (UKOG-0162FCZZ) and the servicing color test chart (UKOG-0326FCZZ/UKOG-0326FC11). Set the copy density level to "3" in the Text/Printed Photo mode (Manual), and make a copy.
At that time, all the color balance adjustments in the user adjustment mode must be set to the default (center).
In addition, be sure to use the specified paper for color.
b. Note for checking the monochrome copy mode density
To check the density, use the gray test chart (UKOG­0162FCZZ). Set the copy density level to "Manual 3" in the Text/ Printed Photo mode (Manual).
In addition, all the color balance adjustments in the user adjustment mode must be set to the default (center).
Check with the gray test chart (UKOG-0162FCZZ)
In the copy density check with the gray test chart, check to insure the following conditions.
For the color (gray) balance, use the servicing color test chart (UKOG-0326FCZZ/UKOG-0326FC11) to check.

(Method 2)
Use SIM46-21 to print the color balance adjustment sheet, and check following image to confirm that the color balance adjustment is proper.
(4) Printer color balance/density check
Before checking the copy color balance and the density, be sure to execute the following procedures in advance.
* Execute the high density image correction (Process correction)
forcibly. (SIM 44-6) * The half-tone image correction is forcibly executed. (SIM 44-26) Execute SIM 64-5 to print the print test pattern.
Set each set value to the default and press [EXECUTE] key. The print test pattern is printed.
The print density must be changed gradually from the lighter level to the darker level. The density changing direction must not be reversed. The density level of each color must be almost at the same level.
The print density must be changed gradually from the lighter level to the darker level. The density changing direction must not be reversed.
The density level of each color must be almost at the same level. Patch B may not be copied. Patch A must not be copied. If the color balance of each patch of the process black (CMY mixed
color) is slightly shifted to Magenta, it means that the adjustment is proper. In an actual print mode, it is converted into the natural gray color balance by the color table. (When the color balance target is DEF 1.)
9-A Scanner calibration (CIS calibration)
This adjustment must be performed in the following cases: * When the CIS unit is replaced. * When a U2 trouble is occurred. * When the MFP PWB is replaced. * When the EEPROM on the MFPC PWB is replaced.
(1) Note before adjustment
- Check that the table glass and the lens surface are free from dirt and dust. (If there is some dust and dirt, wipe and clean. A lens should never be cleaned with alcohol as the alcohol may damage the (yellow) coatings on the lens. Table glass should be cleaned with glass cleaner that has no ammonia it it. It is also preferable to use a glass cleaner with an anti-static additive in it.)
- Check to confirm that the patches in BK1 and BK2 arrays of the SIT chart (UKOG-0280FCZZ or UKOG-0280FCZ1) are free from dirt and scratches.
If the patches are dirty, clean the chart surface area with a soft dry rag.
If they are scratched or streaked, replace with new one.
(2) Adjustment procedures
1) Set the SIT chart (UKOG-0280FCZZ or UKOG-0280FCZ1) to
the reference position on the left rear frame side of the docu­ment table.
Set the chart so that the lighter density side of the patch is on the left side.
If the SIT chart is not available, execute SIM 63-5 to set the CIS gamma to the default. In this case, however, the adjust­ment accuracy is lower when compared with the adjustment method using the SIT chart.
