machine was copying very light as if it wasn't adding toner or the dv was old. I replaced the dv. ran the tcr adjustment .the machine dumped the dv filling the drum clearing unit with dv and going into error code 2803. cleaned out the dv in the cleaning unit. cleared code and ran the tcr adj again. machine went right back into the error code 2803. this is my first service call on this machine. but it seem as if the charge maybe to high or a bias problem. please help! thanks
