Xerox 7556 not printing correct colors

We have a brand new Xerox 7556.  It prints true colors from a color copy made on the copier, but when sending a file from a computer the flesh tones are orange, grays are purple, and blues are faded. 

 

We went through the caibration steps on the copier - tools>calibration - and printed the calibration image.  We scaned that image as a PDF and put that PDF on the computer.  The colors on the screen looked identical to the original calibration copy.  

 

We then printed the calibration image from the PDF on computer (making 3 copies) - the colors were off as indicated above.  We then went through the copier's tools>calibration page and printed the calibration copies again.  However, instead of inserting these 3 copies it just printed, we inserted the 3 copies from our PDF file (computer>copier printout).  

 

The copier then prints a before and after calibration page to compair.  The before calibration page and the after calibration page were identical.

 

The before and after pages should have either been different because it corrected the colors - or it should have been even farther off becuase we're not doing something right.  But they are identical. 

 

Is it possible the print calibration program is faulty?

Re: Xerox 7556 not printing correct colors

Almost certainly is Acrobat/Reader due to it outputting to what it expects is an RGB device.

 

Open a pdf and go to File > Print > Advanced and check the box for Let printer determine color

Or if Acrobat Pro, File > Print > Advanced > Color Management and set it to None

Indesign would be the same as Acrobat Pro.

You do this just once and it will become the new defaults for the selected printer.

I'm out for the weekend so any updates won't be answered until Monday.

Re: Xerox 7556 not printing correct colors

Thanks for the reply.  I did go into adobe and change the setting as you indicated: "let printer handle color."  It returned our greys to gray, blues went back to a closer representation, and it toned down the orange hues in flesh tones.  However taupe colors (light browns) still print pink. 

 

A technician was in today, and had no answer as to why the copier's print calibration wouldn't change the colors when we used our printed copies instead of the "originals" the copier produced.  He agreed that when the copier printed the "original" and the "changes with re-calibration" pages they should have been diffirent - not identical.  He had no way of checking if this part of the copier program was faulty.

Re: Xerox 7556 not printing correct colors

The story continues....

 

Xerox had a troubleshooting tech come from another city to take a look at our 7556 copier/printer.  He was unable to determine why light browns were printing pink.  He took our image back to his office and tried it on an identical model.  He discovered that their 7556 Xerox had the same color issues with light browns. 

 

We've contacted our sales person (as this machine was just delivered a week ago) to talk about a different model that was suggested by the technician.  He suggested the 7900 series machines, as they are supposedly designed for more commercial color print jobs, and not for garden variety office printing. 

 

Any ideas about "trading up" and what we should be aware of in a different model?  Or even hanging on to our color cube (which also had some color issues with red - but we learned to compensate)?

Re: Xerox 7556 not printing correct colors

Get a sample of that job from the 7970.

It sounds like there is something in the color the machine just can't do, and it could easily mean the 7970 cannot either.

An example would be a gradient going from 0-100% in Blue. This cannot be done on any toner based device. They can mostly get away with 10-100% with most shades, but that 1-10%  doesn't allow enough toner to be mixed to make the color without causing a stepping effect in trying to do such small coverage.

Also make sure they don't sample it from a 7970 with Fiery RIP, since that would not be a reflection of what the 7970 controller can do.
