While this is a calibration sheet it does this on all color gets to the end of the page and then looks as it starts to skip (aka chatter) then if you look at the bottom of the page it leaves those morse code looking marks even though that part of the page should be blank. Its no the transfer unit I changed it out same results. Any Ideas? Thanks

And if you could it would be nice to know the direction of paper travel.

I'll go out on a limb here. Being that there's so much talk of lasers today ... and the specks are only K of varying density and in a neat row main scan direction, I'll call it laser.:

I'm filing all this knowledge away. keep it coming.

@Billy: Notice the tool "Colorpic".

If you cannot find it, I can get you a copy. =^..^=

I did notice it but I'm not quite sure what I'm looking at or how you used it for the dots on the page. You're gonna have to break it down for me. Forgive my ignorance.

I have not used it but it appears that the red circle is the pointer for what you want the tool to examine. ColorPic then shows you the breakdown of the color(s) of the area selected.

I'm thinking black pcu. How many copies on the PM items? What model machine?

I see. Sorta. This is software tool that analyzes colors. I wasn't paying close enough attention. But I'm still unsure how it's being used to troubleshoot the laser??

Re: Chatter on color only

Colorpic allows us to get a CMYK or RGB color breakdown of any/every pixel of any electronic document in any application. If you can display it on your PC, you can define the pixel color.

Here's a good example of where this is helpful: Customer presents you with a printed page. "The green doesn't match our press printed business cards." So I get a copy of the electronic file, the same file used for both images. I sample the green, it's C: 32, M: 0, Y: 67, K: 2. Roughly Pantone 7737C.

Pantone 7737C-Hex 87B240.jpg

Now you might have seen this diagram before.
The full circle defines the colors that can be seen with the human eye.
The yellow outline defines RGB colors, like what you can see on your PC monitor. Clearly less colors.
The red outline defines Pantone ink colors. Less than either the RGB colors or the full gamut.
The blue outline defines CMYK colors, or what your MFP could conceivable print. So there are a LOT of colors that you can see with your eyes, or see on your monitor, or print in ink, that you just can't print with a CMYK printer ever. How can you quantify that?

Well, if you find 32/0/67/2 on the image, it's where that little yellow star appears. It's right at the top where RGB and Pantone colors intersect, but far outside the realm of possibilities for a CMYK printer.

You know the best part? My enduser says to me: "So be best thing we could do is just pick a color that the printer CAN print!"
Oh, yeah! If only I could get so many other people to get that concept.

I can tell that each of those specks is ONLY K of varying percentages, with no C, M, or Y. And it's in a pattern in the main-scan direction, like a laser writes.

I love it. And I understand now. Thanks for sharing.
