In theses machines you have three reasons to have light copies:





1-If the toner motor is blocked you have compacting toner in the hopper the toner gear (color green) does not turn to let toner to goes in the developing unit check it in 47 mode 01 to see if toner motor is feeding toner if it is ok go to step 2.





2- Drum life if the drum is old it gives light copies you have to change it and reset the counter 47 mode 91 if not an old drum go to step three.





3- Replace the developer and do the calibrating on 47 mode 51 it will run about three minutes after it will stop.





N.B to enter to service mode, you have three choices 47, 25, 36 modes


Turn off the machine to enter to service mode press 47 or 25 or 36 you have to press 4and 7 in the same time and press the main switch and keep pressing on the button 47 or 25 or 36 see the attachement file ,good luck.

Everything TALALOO said is correct, but I would start by making sure the Optics and Corona wires are Clean. If you are set to Auto Exposure and it jumps to the lightest setting It is more than likely that your optics need cleaning.
