I am having workcentre 24, CMYK colours tone are not printing properly mainly cyan and majenta

clean the print heads and align them

Blocked print head nozzles
You may have blocked print head nozzles.
Try the printer maintenance to clear the printer nozzles.
After several deep cleaning attempts and there is no improvements in the print then a new print head is required.
A new print head maybe expensive and it maybe more cost effective to purchase a new printer.

No, that's not what it means.
If printer heads are not aligned, CMYK colors (Cyan, Magenta, Yellow and blacK - the usual colours in a printer) will not print in the correct place.
Assume a dark grey dot is to be printed. For this C, M and Y colored dots have to be placed exactly on the same spot. But if heads are not aligned, the three color dots will not be exactly in the same place. Therefore you will see Cyan, magenta and Yellow dots adjacent to each other instead of one dark grey dot.
It is always a good idea to align the print heads every time a new cartridge is installed.

Hi there! The blue color is becoming violet because the Cyan and the Magenta toners are not getting mixed in the proper 100:100 ratio (100% Magenta and 100% Cyan make CMYK Blue). Since the print is violet, the culprit is the Cyan toner. Now, first, get the Cyan Developer Assy checked if there is enough developer in it. If no, get it refilled by a proper tech and manually mix about 50 grams of the Cyan Toner with the developer. Also get the tech to check the trimmer gap on the Developer Assy with a metering gauge. If yes, next check the Cyan dispenser motor located on the backside of the Toner Housing Assy. It is probably broken and not dispensing any toner to the Cyan Developer Assy . Additionally, check for the Cyan Dispenser Auger blockage or jam. It is located under the Cyan Toner Cartridge in the Toner Housing Assy and also check the auger under the Cyan Developer Assy. After sorting these out, you should get proper CMYK blue from the 10th or 12th page once you resume printing.Let me know. Regards

Solution : Perform an Automatic Gradation Adjustment (Color Calibration) Automatic Gradation Adjustment compensates for tones when the color tones shift in color copies / prints. Compensating for color tones maintains the quality of color copies / prints made by the machine at a fixed level.

NOTE: Output of the Automatic Gradation Adjustment chart is added to the metered copy count.

NOTE: When Gradation Adjustment is selected, the following changes will be made to default copy settings set in System Settings mode:

• Copy Density = Normal or Auto
• Color Shift =Normal
• Saturation = Normal
• Color Balance = 0
• Sharpness = 0

1. Press the [Access] button (key symbol) on the Control Panel. The Access button is located above the number "3" on the numeric keypad.
   
   
2. Using the numeric keypad, enter your administrator password and select [Confirm] on the Touch Screen. The System Administration Menu screen will be displayed.
   
   NOTE: If you do not know the password, contact your administrator. The initial password at machine install is 11111. If the administrator encounters a problem with changing the password, or forgets the password, a service call must be placed.
   
   
3. Select [System Settings]. The System Settings screen will be displayed.
4. Select [System Settings] again.
5. Select [Common Settings].
6. Select [Image Quality]. The Image Quality Adjustment screen displays.
7. Select [Automatic Gradation Adjustment].
8. Load 8.5 x 11 inch (216 mm x 279 mm) or A4 (210 mm x 297 mm / 8.3 x 11.7 inch) paper in Tray 5 (Bypass Tray). Adjust the paper tray edge guide so that the guide gently touches the edge of the paper stack.
9. Select the desired gradation adjustment screen.
10. Press [Start]. The Adjustment Chart is output.
    
    NOTE: When printing the color chart for Auto Gradation and you get the message,'Auto Graduation Procedure has completed with an error' make sure that 8.5 x 11 inch (216 mm x 279 mm) paper is loaded into Tray 5 Long Edge Feed (LEF).
    
    
11. Place the Adjustment Chart face-down on the Document Glass with both the Magenta color patches against the left side of the glass.
12. Place 5 sheets of white paper on top of the Adjustment Chart and close the Document Glass Cover.
13. Press [Start].
14. To continue Automatic Gradation Adjustment with other screens, repeat steps 6 to 10. When you are finished, select [Close] until the System Settings screen is displayed.
15. Select [Exit] to exit the System Settings mode.

Hope it helps!

Start with this

1. Make sure to set the Print Quality mode in the print driver to "Standard" and the TekColor Correction to "None" before performing the next step. This will allow the job to purge only the problem color. Other settings may cause the printer to use a percentage of the other ink sticks.
   
   
2. Print approximately 50 - 100 pages of the document, as necessary, until the printed color returns to normal.

Next. This is on xerox.com downloads and drivers.

The updated sRGB Display and sRGB Vivid color tables for the WorkCentre will help with the following issues that have been found with the original factory color tables.

• RGB images contain too much yellow.
• RGB image red shades are too orange or too light.
• RGB object blues are too dark or aqua.
• CMYK objects use the sRGB Display color table when the Automatic TekColor correction is used. After the updated color tables have been downloaded to the WorkCentre, the CMYK objects will use the Commercial Press TekColor correction when Automatic is used as the TekColor correction.
  
  NOTE: The new color tables will only take affect when using the Enhanced or High Resolution / Photo print quality mode.

To update the RGB color tables:

1. Click on the [Drivers & Downloads] link under the Product Resources menu on this window to download the updated color tables to a known location on the computer's hard drive. The color table update file is located under the Color Profiles section on the Drivers and Downloads page.
2. After the file has been downloaded to the computer, send the file to the WorkCentre. See the Related Items below for additional information.

Here is a list of reasons why colours on electronic designs might differ from printed designs:

• Monitors work in the RGB (Red,Green,Blue) colour space while printers use the CMYK (Cyan, Magenta, Yellow and Black) colour space.
  Designs look fine on a monitor if they are designed in RGB to begin with. Converting them to CMYK might make them look odd on screen, but they will print correctly, to a certain measure. It is difficult to sign of an image file that is currently in CMYK mode while viewing with an RGB monitor.
• Monitor settings differ.
  The designer was sitting in a darkish room when choosing the blue and his blue looks vibrant. The client was viewing the same design in a well-lit room, making the blue seem lighter. The designer uses an LCD display and the client uses a CRT monitor and the vibrancy differs. The contrast and saturation settings on each monitor might differ as well, rendering the blue with different values.
• Each printer in the world prints colour slightly different.
  Sometimes it is really obvious and sometimes it is almost impossible to see the difference. Normal desktop printers are definitely not something to do colour proofing with. If you print the design out on your desktop printer then a slight shortage on any of the colours will make the colour come out wrong. There are a lot of factors that can influence even the most expensive printing equipment. These include altitude, humidity, the current heat of the printer, age of the printer, quality of ink, the paper that is being used, special coatings on the paper etc. Even viewing the same printed material in different lighting conditions may make the colour seem different.

Tips on getting the most accurate colour
Go to your nearest printer company and ask to see their Pantone colour matching system. Each colour in the Pantone chart has a matching number. Most design applications have the same Pantone charts built in so that colour matching is easy. Read up on Pantone at Wikipedia. Make sure that the file is converted to CMYK (If not designed in it originally) before sending it to print. Some printer companies might ask for colour separation prints which the leading design packages can produce. It is also important for the designer to choose the correct colour management profile in the design package.

I eliminated everything except two new non HP majenta and cyan cartridges. I removed the cyan cartridge and replaced it with an empty magenta cartridge, giving me 2 magenta cartridsges and althought it didnt printy, it staretd to pick up the paper so paper feed was working. I knew then that the cyan cartridge was faulty and changed it. All works now

For optimum printing results change your cartridge not long after the printer is reporting low ink levels.

Printer cartridges print in CMYK (Cyan, Magenta, Yellow & Black)
