As far as the OPC belt - don't replace it until you start seeing ghosts and image defects! Reset it by:
Press 1 and 7 at the same time
Press 1 to reset the life counter.

if it does this on all colors, try cleaning the laser **** glass located below toner cartridges. you could have drops of toner on it. if only certain colors, visually check your toner cartridge rollers.

Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.
This will reset the purge count value. Then the printer will restart, try this step by step.without missing any thing. thanks
