    If it's been sitting awhile I would dump and vacuum DV and dry wipe the cylinder and add fresh toner. I've had to do this before.

    There was an issue with the developing stirring rods breaking or not turning.

    See TP17 243a Countermeasure against poor density or white band image.

    These machines have a history of light density printing.

    I've lost count of how many stirring rods that I've changed on these things..

    I have noticed in using the correct thickness of corona wire makes clear copies. For eg. 60 microns results in blacker, clearer copies as compared to 80 microns (based from services) IRA 6055/6255 models even on IR5000/6000s. Another thing is the Drum might have been sensitive to light already, what I do is I improvised a dark red penetrating cover on the drum assembly part to dim the lights a bit which is flashing directly above it (helps with darkening the images also). This is of course right after you did these processes.
    *cleaning the drum, replacing the drum cleaning blade, cleaning the developing assembly from paper dust/old toners, cleaning the platen glass, cleaning the scanning unit prisms and then of course configuring the numerical values in the service mode. Then you have the case of old papers that hang around, try freshly opened ones.

    +1 for deactivation of potential control for testing.But ,before this,i would check the DPOT values in service mode.From there,you can have a clue where the trouble is.Also check if the drum heater is on.

    Good luck.
