[Misc] HP Color LaserJet MFP M274n - bad colors at copies only (scan good colors)

[spree]

Hello,
I have here HP Color LJ Pro MFP M274n:
- with non genuine cartridges!
1.) printing is excelent - see scan image attached
2.) scaning is good - see scan image attached
3.) but copies are not good - colors are not good - best to see at yellow color - see scan image attached
What was maked:
- flashing the newest firmware (
- reseting the printer to the defaults
- NAND reset (in 2nd service mode)
- perform Scan Calibration (in 2nd service mode)
- perform Super NVRAM initialization

Still the same problem.

Where can be the problem (bad scanner assembly - B3Q10-60125 ?) or some electric board?, but scaned image has perfect colors, but copies have not good colors.

start by installing genuine carts - the cyan doesn't look like it's quite the right color and i've seen this a few times
