1. IMAGE ADJUSTMENT

   
   

   1. AUTO COLOR CALIBRATION

      For the best image quality, this is done during installation, and should be done periodically by the customer. It is accessed with the user tools as follows.

      User Tools -> Machine Features -> Maintenance -> Auto Color Calibration

      
      

      • When you set the adjustment sheet on the exposure glass, put about 10 pieces of white paper on the adjustment sheet in order for the original to contact the exposure glass sufficiently. Instruct the customer to periodically execute the ACC.

        

        
        

        
        

        	Description
        [A]	Output adjustment sheets. You must execute both for copy and printer functions.
        [B]	Roll back to the previous value.
        [C]	Displays the last date/time ACC was executed.

        
        

        About the printer ACC

        It is difficult to keep constant printing density due to the environment of the machine, individual differences between devices, and the passage of time. The printer ACC reads the current printing density using the scanner, and then compares the result with the time when it was in a normal state, and makes the printing density close to the normal state.

        Issues possibly solved by the printer ACC

      • When the printed image looks strongly red, blue, or yellow because the density of the cyan, magenta, and yellow are not balanced.

        

        Replacement and Adjustment

        • When the printed image looks too dark or light.

          
          

          

          Issues cannot be solved by the printer ACC

          The tone differences from other types of machine or machines of other manufactures cannot be solved by the printer ACC. The tone differences from the machines of other manufactures occur due to the differences in color reproduction caused by the difference in the engine and color profile specifications so it may not be solved even after performing the printer ACC. Refer to page 4-228 "Adjustment by Changing the Machine’s Profile Setting" for the color tone differences from the other types of the machine.

   2. SCANNING

      Brightness

      • Decreasing the brightness makes the printed image darker and increasing it makes the printed image fainter.

      • Decrease the value to make the printed image darker and increase it to make the printed image fainter.

      • If you increase the value too much, overexposure of bright areas may occur.

      • If you decrease the value too much, underexposure of dark areas may occur

      • Can be specified using the PCL/PS drivers.

        
        

        

        Contrast

      • Increasing the contrast makes bright areas brighter and dark areas darker.

      • Decreasing the contrast makes bright areas darker and dark areas brighter.

      • Increase the value to make the printed image clearer and decrease it to prevent overexposure of bright areas and underexposure of dark areas.

      • If you increase the value too much, overexposure of bright areas and underexposure of dark areas may occur.

      • If you decrease the value too much, the printed image may become unclear.

      • Can be specified using the PCL/PS drivers.

        

        
        

        Replacement and Adjustment

        Saturation

      • Increasing the saturation makes the printed image more vivid.

      • Decreasing the saturation makes the printed image closer to the neutral color (gray).

      • If you increase the value too much, it may lower the gradation, resulting in a difficulty to distinguish colors.

      • The printer’s color gamut is limited, so even if you increase the value, it may not make any difference.

      • Can be specified using the PCL driver only.

        
        

        

        RGB Adjustment (Adjust Each Color)

        When using the PCL driver, adjust the tone (color gamut) by this method.

      • Increasing "Red" makes "M" and "Y" more vivid and "C" less so.

      • Decreasing "Red" makes "M" and "Y" less vivid and "C" more so.

      • Increasing "Green" makes "C" and "Y" more vivid and "M" less so.

      • Decreasing "Green" makes "C" and "Y" less vivid and "M" more so.

      • Increasing "Blue" makes "C" and "M" more vivid and "Y" less so.

        

      • Decreasing "Blue" makes "C" and "M" less vivid and "Y" more so.

      
      

      CMYK Adjustment (Adjust Each Color)

      When using the PS driver, adjust the tone (color gamut) by this method.

      

      
      

      Adjustment Examples

      The following shows adjustment examples. Be sure to check the printed image when changing values.

      If the printed image is dark:

      Increase the brightness by 20.

      
      

      

      If the printed image is faint:

      Decrease the brightness by 20.

      
      

      

      Replacement and Adjustment

      If the printed image is too bluish:

      Increase "Red" or "Magenta" by 20.

      

      If the printed image is too reddish:

      Increase "Blue" or "Cyan" by 20.

      

      If the printed image is unclear:

      Increase the contrast by 15.

      

   8. ADJUSTMENT BY CHANGING THE MACHINE’S PROFILE SETTING

      You can change the printer’s profile setting by specifying a bit switch in SP mode.

      
      

      • By changing the profile setting, you can change the tone of all images printed by the machine’s printer function.

      • By changing the profile setting, you can make the tone (image gamut) of the printed image similar to that of another model. However, due to factors such as the image gamut difference between different models, individual differences, and ageing of components, you may not achieve exactly the same tone.

        
        

        Procedure to Change the Profile Setting

        1. Enter the printer SP mode.

        2. Change the values of bit switches with the following SP numbers.

           
           

           Desired tone (color gamut)	SP to change	Value to select
           2009 Spring model or those before it	SP1-001-002	00000001 [01H]
           2009 Autumn to 2011 Spring model		00010000 [10H]
           2011 Autumn model or later		00000000 [00H]
           Fuji Xerox product	SP1-001-001	10000000 [80H]

           
           

        3. Turn the machine’s power off and then back on.

           The specified setting is applied.

             Standard profile for MP C3002/C3502/C4502/C5502 up to the present model.

             Compared to Color B, the difference between colors have become more recognizable. On the other hand, the printed image has become slightly less vivid.

             If you receive a comment that the printed image is less vivid compared to that of a Color B-standard model, we recommend changing the setting to Color B.

             Color D

             Profile with a tone similar to that of the prints by the FX products.

           • Bluish colors appear slightly purplish. (Image of the sky appears with a slight tint of red.)

           • Pink in the printed image appears with a tint of magenta.

   9. PRINTER GAMMA CORRECTION

      
      

      • We recommend that you keep the printer gamma correction values at the default values.

      • The values adjusted/saved in the printer SP mode are applied after the machine’s power is turned off and then back on.

      • After adjusting/saving the values in the printer SP mode, make sure not to perform the printer’s Auto Color Calibration (ACC). Doing so will reset the values.

      • To change multiple resolutions, perform this procedure for each resolution.

        1. Select the mode you want to change in the printer SP1102-001: Resolution Setting.

           
           

           1102	[Resolution Setting]
           	Selects the printing mode (resolution) for the printer gamma adjustment.
           001	Resolution Setting	CTL	[0 to 9 / 0 / 1/step] 0: 1200x1200 Photo (2bit/4col) 1: 1200x1200 Photo (1bit/4col) 2: 600x600 Photo (4bit/4col) 3: 600x600 Photo (2bit/4col) 4: 600x600 Photo (1bit/4col) 5: 1200x1200 Text (2bit/4col) 6: 1200x1200 Text (1bit/4col) 7: 600x600 Text (4bit/4col) 8: 600x600 Text (2bit/4col) 9: 600x600 Text (1bit/4col)

           
           

        2. Change the gamma correction value for each color in the printer SP1104: Gamma Adjustment.

           • When adjusting the value, be sure to follow the sequence: I M S (Shadow) H (Highlight).

           • To lower the print density, reduce and save the H/M/S/I value for each color.

           • To heighten the print density, increase and save the H/M/S/I value for each color.

   10. COLOR REGISTRATION

Adjust color registration with the following procedure when color registration errors occurred.

Check the Occurrence of Color Registration Errors

Prepare some A3 sheets.

1. Execute SP2-111-004 (Forced line Position Adj.: Mode d)

2. Make sure that execution completed successfully with using SP2-194-007 (MUSIC).

   If the value of SP2-194-007 is "0", it indicates that the result of SP2-111-004 was successful. If the value of SP2-194-007 is "1", it indicates that the result of SP2-111-004 was a failure, which you need to fix the color registration errors (See "Ways to fix color registration errors" (page 4-233))

3. Execute SP2-109-003 (Test Pattern: Pattern Selection)

4. With a loupe, check the details of the color registration errors on the printed test pattern. (page 4-233)

   • Specification: Main/Sub is smaller than 180.0um

   • No color registration errors: Adjustment completed.

   • Color registration errors occurred: Adjust the color registration errors (See "Ways to fix color registration errors" (page 4-233)

Judgment for Type of Color Registration Error

In the following diagrams, solid lines represent "K" and dotted lines indicate any of "C", "M" or "Y".

1. Pattern 1

   This is a case in which there is a shift in the sub-scan direction at the leading edge of the paper. The following diagram shows "C", "M" or "Y" lines closer to the leading edge than "K" lines.

   
   

   

   
   

2. Pattern 2

   This is a case in which there is a shift in the sub-scan direction at the trailing edge of the paper. The following diagram shows "C", "M" or "Y" lines farther away from the leading edge than "K" lines.

   

3. Pattern 3

   This is a case in which a color registration error is found in the main-scan direction and size of the error is the same at the left, center and right.

   
   

   

   
   

4. Pattern 4

   This is a case in which a color registration error is found in the main-scan direction and the size of the error is different at the left, center and right. For "M", the largest error will be at the right, followed by the center and then the left. For "C" or "Y", the order will be reversed. This is because the writing direction of the laser beam for "K" and "M" is different from "C" and "Y". Case "M"

   Case "C" or "Y"

   
   

   

5. Pattern 5

This is a case in which a color registration error is found in the sub-scan direction, but it is not the same as the Pattern 1 or 2. The error appears and disappears at intervals down the page.
