Question about Xerox DocuColor 12 Printer

2 Answers

Gradation Problem When I print a gradient it comes out chopping rather than smooth. There's actually hard breaks in the succession of color rather than a smooth transition between the colors. This came about when Xerox came out and replaced both IBT's and all of the developer as I was having problems with prints coming out grainy and degraded. Strangely, it was fine after the IBT's were replaced but became a problem after the developer change. They ran Max setup after all the work was done and of course everything checked out OK. I've tried adjusting the Low and Mid range toner concentration but not luck. Any thoughts?

Calibration is all thats needed, from your fiery or splash. These machines are rebuilt all the time and they bounce abck from everything. Dev change will just make the colour better, not worse, but its down to you to keep it calibrated

All the copies and print outs are black colour. Why is this happening?


Have you check the gradation print out for each color in the service mode? Recommended that you do that. Does this happen in printing or copying? There is a difference. Any warning to replace certain parts? Check consumables what needs to be replaced? What does the demo page look like? Are the image units OEM? is the transfer belt OEM? Service mode + Counter, details, stop00 stop01, output, gradation pattern.

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!

Xerox 7345 color comes out orange instead of red.


If you go into your User settings. Login 11111.
What you want to do is the Auto Gradation adjustment. It will print out a test pattern and you will place it on the glass and scan it.
I think there are 4 times you repeat it, for copy, print, photo print.
That should correct it. There is also a Tec Color adjustment on your print driver if the issue is only when you print.

Oh, it's the colors you are having a problem with. Then you probably want to perform an Auto Gradation Adjustment. It's on pages 162-163 of the manual found here: http://download.support.xerox.com/pub/docs/DocuColor_3535/userdocs/any-os/en/3535_User_Guide.pdf

Here is what it says:

Auto Gradation Adjustment
Auto Gradation Adjustment is a color calibration for the copier and printer. An Auto Gradation Adjustment compensates for differences between the actual and the expected toner densities for each color. An Auto Gradation Adjustment should be performed whenever there is a noticeable change in the appearance (quality) of the output, particularly changes in color
tones or densities. Performing an Auto Gradation Adjustment on a regular basis will help to maintain consistent color quality over time.

NOTE: Since an Auto Gradation Adjustment can affect all jobs for all users, it is recommended that this procedure be performed only by the Machine Administrator.

Copy Job - Text Compensates tones when a text original is copied.
Copy Job - Photo Compensates tones when a photo original is copied.
Print Job Compensates tones when printing with controller line screen.
Network Controller - 1 Compensates tones when printing with Network Controller screen type 1.
Network Controller - 2 Compensates tones when printing with Network Controller screen type 2.

NOTE: Printing the chart for Auto Gradation does not increase the meter count.
NOTE: When gradation adjustment is executed, 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.
NOTE: When Print or Network Controller gradation adjustment is executed, the printer’s output profiles for the available screen types are compensated.

1 On the Image Quality Adjustment screen, select Auto Gradation Adjustment.
2 Load 8.5x11 inch or A4 paper into Tray 5 (Bypass). Move the paper guide to gently touch the edge of the paper.

3 Select the desired gradation adjustment screen:
• Copy Job - Text
• Copy Job - Photo
• Print Job
• Network Controller - 1
• Network Controller - 2
Press Start. The Adjustment Chart is output.
4 Place the Adjustment Chart face down on the Document Glass with both Magenta color patches against the left side of the glass.
5 Place 5 sheets of white paper on top of the Adjustment Chart and close the DADF. Select Start.
6 To continue Auto Gradation Adjustment with other screens, repeat steps 2 to 5. When you are finished, select Close until the System Settings screen is displayed.
7 Select Exit to exit the System Settings mode.

Tektronix phaser 7300 uneven inking


sounds like a bad cyan developer housing. Or that somehow the housing has come out of its mounting, but I cant think how that would happen. There are some rails in the machine that may have also come loose.
You have to remove the IBT ( transfer) assembly to look into that.
