I have a 3070L that is printing things in an almost monochromatic tone. As you can especially see with the one example most of the color isn't even present in the image compared to the computer file. I've ran tests on cyan, magenta, yellow, and black test pages. (plain color) and nothing showed up. I'm guessing it's a software problem but does anyone have any ideas?

Re: 3070L printing with very little color
Assuming all OEM toners, drums, and developers in the machine?
Step 1. Make sure the paper settings are correct for the media. (Coated Gloss, Coated Matte, Plain, paper weight, etc.)
Step 2 Run the automatic gamma adjustment under drum peculiarity. Make sure the calibration completes without error.
Step 3 Run auto color registration under machine > quality (again completes without error)
Step 4 Run the density balance adjustment for all the different types of media.
Step 5 Calibrate the Fiery in Command Workstation for all media types. (Providing the machine has a Fiery) For Konica print controller, use color centro. Both methods will require a spectro-densitometer
This should bring colors into spec providing the machine is mechanically sound with good supplies.
Keep in mind as well. I've had customers complain about the colors of one machine as compared to another that has hotter or different colors.
Only to demonstrate after a complete calibration that the machine being compared to with hot colors is actually wrong.
Also, colors on a computer monitor will never match what's printed on paper. Colors on a monitor are rendered using RGB additive process where as printed media used CMY subtractive process. -
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: 3070L printing with very little color
Look at magenta ... drum, developer, primary charge, or some combination.
But yes the calibration helped immensely. =^..^=If you'd like a serious answer to your request:

Re: 3070L printing with very little color
I did create these test patterns, and used them exclusively on every model for about a decade.
The places I see the defects are:
*The muddy appearance of the 11% fill magenta pattern (think of moist paper).
*Look at the composite black gradations (CMY black looks sort-of brown colored), in the 10% to 25% fill ... do you see how it doesn't look brown, it looks magenta?
With practice you'll be able to see these things pretty quickly. I carried a USB stick with pattern sizes from ANSI 1/2 A (statement size) up to ARCH E (36" x 48"). If you print the largest paper size the machine can accept, you'll see the full drum surface, and be able to identify repeating patterns pretty easily.
Your 3070 will print Super B (13" x 19") with slightly wider front & rear voids. Most of my printer customers had no problem stocking or cutting whatever size I requested. As a matter of fact the printers all had this PDF image, and left samples of my test image ... which is extraordinarily helpful on intermittent issues.
If you need a specific sized image just PM me. =^..^=Last edited by blackcat4866; 01-27-2024, 04:58 AM.If you'd like a serious answer to your request:

I have Blackcat's test charts saved to a USB drive as well. They are indispensable for isolating image quality issues!!!Comment

Re: 3070L printing with very little color
I was working on VoyagerE's at the time, before machines came with the built in test patterns. But they all did have USB ports and printing from external memory.
You know how customers save unique quality samples to demonstrate their problem? I paid special attention to what patterns and colors showed the defects most clearly. When you use manufacturer test patterns, they hire artists to create patterns that DON"T show defects. Who wants to see the defects? Well, the technician does.
So my patterns are built around finding defects, not hiding defects. Here's a good example: Ask any printer what color is the most difficult to reproduce a smooth solid color. Most of them will say Henry Ford Blue (C:100, M:47, Y:0, K:55) or something close. So defects are plainly obvious, and intervals easy to measure. When you're dealing with printing companies it is a complete waste of time show them manufacturer test images. They know the machine inside and out. They know color. You just can't tell them that there isn't a problem.
Maybe the most useful part is the CMY composite black gradations. Each color is in equal proportion, and the defects are undeniable. In retrospect, I might have added a full page 11% CMY composite black page. If you use these pages, you'll know that KM production devices can print down to 5% fill smoothly, but that 5% image on a Samsung or Brother will be completely blank.
Sorry for the rambling. I did put a lot of thought into the elements in those patterns, and they have evolved through 4+ image revisions, & 38 standard paper sizes. =^..^=If you'd like a serious answer to your request:

Re: 3070L printing with very little color
Hello, I think you have problems with the highlights, you still have to make these adjustments Service->Machine adjustment->Quality adjustment->Gamma curve adjustment->IDC sensor adjustment.
Service->Machine Adjustment->Quality Adjustment->Gamma Curve Adjustment->Highlight Automatic Adjustment,
[Enter Utility] -> Administrator Settings -> System Settings -> Expert Adjustment ->Quality Adjustment ->Auto Density Balance Adjustment.
Then, if I were you, I would create an icc profile because using the default fiery profiles is not highly recommended, if your clients are very critical of color
thanks
