Hi,

I think that the yellow is darker in center of print than border !

In this case the laser's lens is wrong, it is necessary to replace the yellow laser module.

If the color (yellow) is NOT regular from left to right, that's because the corona is not parralle to drum, you need to put an adhesif on the corona.

Kind regards,

Twinax

Some of the charge corona's for those boxes are KNOWN to come not set correctly. Crack open the covers and make sure the corona wire is set properly.
