Run Factory Default under Recall Standard Data under Process Adjustment.


Then run test pattern N. 80 and compare the colors


Do not let the printer adjust. Run the test right after the Factory Default.

colorful ...
very nice colors ...

after gamma adjustment and color registration

Re: C6500 - color density problem

I start to think that the problem starts from gamma sensor,
when I cleaned boards from gamma and color registration sensor can be that I touch this 2 adjustments...


can I find right position of them, or can I readjust them?

thanks!

Re: C6500 - color density problem

replace, if cleaning didn't fix. Usually overcompensates the other way when dirty.

how many test prints did you run before it go lighter, before adjustment? i would have ran a bunch just to be sure it didn't lose density on it own.

Changing would be the best alternative. However, in the printed tests, it seems to me to have a developer with a shelf life at the end.


Cyan prints bad colors.


The yellow background after the adjustments is a faulty gamma sensor characteristic.


But be sure to change the developers if necessary.


This sensor strip has an update. Pay attention when making a purchase.
