Scratch that, if you change the preferences in the PS driver you can lower the saturation if the color is too dark, or increase the lightness if everything is too dark. PCL driver has no color controls.
With a calibration done for print all you really have left besides a tech visit for a hardware caused issue, is to try the settings here in Properties > Services > Printing > Page Description Languages > Postscript.
I submit the PDF file, the result is the same : too dark :(
maybe another version of firmware can correct this ? ( i Know how to downgrade with ALTBOOT method in case)
@ Fiery : Hello, thanks for your support. Yes I made a callibration.
Go to CWIS and submit the pdf file that way using all default settings.
If it prints fine, the issue is Acrobat/Reader and would be solved via File > Print > Advanced and enable Let Printer Determine Color
Outside of PDF you would need to do some driver changes. Set Color Matching > In Printer
and Xerox Features > Color Options > Custom Color Options > Color Correction to None
If this part makes it work you would need to set it as the defaults in CUPS since Apple long ago decided you don't need to change printer defaults within the driver.
first, i want appologie for my poor english, i'm french.
here is my problem :
Workcentre 7830 with buit-in Controller (new device - just installed)
firmware : 072.010.165.14201
OS : Mac OS X v10.10.5
Driver : Universal Binary Mac OS X 10.8, 10.9, 10.10, 10.11 V3.64.0 (1572)
file to print : pptx file or PDF file (pptx file saved as a pdf file)
as I say in the title, the result of printing is realy too dark
- I tried in color auto mode and hight résolution mode, it's the same result.
- I tried different color correction mode, but the result is too dark again.
maybe someone have a "magic solution ' ? ^^
ty for your support.
