I have one machine with 3 mil copies and some problems , The ecquipment is buyed 2 weeks ago .

If the ecquipment work with default factory settings everything is ok , the print quality is good .
After a time the machines make automaticly Auto gama adjust , after this calibration the colors are very week , the print don’t have the normal intensity of colour . The intensity is at 50% for normal print .
On the service menu the “bias of developer” on yellow by default is set at 522 after Auto Gamma adjust the value is 288 , the same situation for Magenta – factory default is 488 after Auto Gamma Adjust is 276 .

I tray to fix the problem but no succes untill now , any suggestion are wellcome !

Sounds like a firmware issue to me or a faulty "Gamma Sensor". Try the latest firmware first. do a recall standard data and then run Auto Gamma, printer gamma sensor then printer gamma offsett.
