almost sounds like your Developer is shot, I would try replacing the powder, and also check the laser settings, if the lasers are too dark it will undertone the powder. how does it look on the drum, it may be a transfer problem, possible bad carona wires, and possible toner density control board. good luck

if this machine has got an ATDC sensor that looks at the drum, there might be a buildup of toner on this and giving the m/c false readings toner wise. not familiar with this model, but you never know.

JRF is probably right the gears at the rear of the toner mechanism at the rear of the machine might be bad. What is the counter on the developer. Have you checked the drum sensor board.

Have you check DID YOU REALLY have a toner issue. Remove the Dev Box and tоuch the magnetic roller with finger. did you get dirty with toner, if you are the problem isn't in the toner supply.
Try to add some toner directly in the DB. Are the copy better? If it is - there is a toner issue.
