Ricoh Im C6000 scans missing light colors

[error404]

We have a Ricoh IM C6000 and we are finding that while prints look good, a copy of the same image is missing the lighter colors. We thought it was drums/developer but was changed out the drums and found no difference. What we did find however is the scans simply are not seeing the colors (scan to email to verify) so it's not going to print them. Cleaned and then replaced the ADF assembly as well as theunder glass lens/mirror assembly to rule out the hardware. Several color calibrations and color registrations. I'm at a loss, if anyone has any suggestions I would greatly appreciate it.

So much talk about scan quality.
Scan a colour test page, and upload it for us to have a look.
A sample is so much more helpful....

The prints in person are spot on, but in copies the 10% is gone completely and half of the 20%. For instance in the flyer at the bottom left hand corner, there is a background behind the text, this is just simply not detected.

A photocopy will never be as good as a print job. the copier only runs at 600x600 dpi. printing is done at a much higher dpi.

What mode are you using while photocopying? text/photo? playing around with the original settings/density may help.

You're expectations are WAY TOO HIGH.
Leo's right, there are some settings that might bring up some of these (very faint to begin with shades); However,This is a business MFP, not a printing press.
There's no issue with these images.
Moving on....

Dear, I just hope that no comments have been made about this in front of the client, otherwise he will criticize you and demand that you provide what the machine does not provide.

No, they have unreasonable about their expectations before I ever got on site. When I advised that printing is 1,200x1,200 where copies are 600x600 I keep getting met with its printed just fine before and that’s it’s never done that in the past. Then the icing on the cake is the pink is not pink enough. My gut feeling is they are trying to get out of their lease. I do agree that the colors are not perfect but it’s no different then when I printed and copies the same on a Xerox C8155. Thank you all for your feedback, was hoping I was just overlooking something.

If you have another similar model machine you could take the originals to test on to see if it has the same issue. It would help rule out the copier itself to prove to the customer that its not a copier problem

Are you making copies of the printed flyer, if so it will always be lighter.

I worked for 10 years with Xerox Pro "Digital Press" machines and NEVER was a copy as good as an internal print. I also had trouble with the scanner picking up some faint pastel-like colors. These usually came from a local artist who wanted us to make prints of their work. This all was at a local Minuteman Press I used to work for.

I don't know if it's my monitor, but I see the colors a little weak.
it's true that the photocopy will never be like the internal print... but it would be interesting to check the "counter pm status" here...for the rest loloculus is right, to cut the head of the bull you should try with another machine of that series, as long as it mounts the same optical sensor.
personally I think it's like saying... the seat of a car, it's not that they give you a perfect one for you, you have to adjust it according to your needs.

What I am seeing is a grayscale shift. Such a shift is usually caused by a dirty scan of the white reference. It could be from a dirty white reference or scanner components.

instead of using the print to make a copy, why not just make multiple prints?
