I have a problem with this SC302 / can I have an answer? Thanks in advance

There is a charge leak coming from the charge roller in the drum area.
Check the PCU connector as well.

everything looks fine and in good condition in PCU, and the connector are ok / any other ideea? thanks for your answer

If you checked the PCU and connections and they are OK, then you have a failed High Voltage Power Supply

Charge Corona Output Error
Grid Voltage Error
Charge Roller Current Leak

tungnhung,
Just curious. Are you reading from the right book? I've seen errors in a couple of your answers to recent posts that would lead me to believe this.

In this case, how would a "charge corona output error", or a "grid voltage error" come in to play in this machine model? (My manual does not mention this.)

certinproject,
You are on the right track with the PCU. Take that PCU apart again. Triple check every metal piece that touches another metal piece near the charge roller and drum. Make sure those that should be are making good contact and are clean. I assume you have an OEM drum and charge roller in there that are new or fairly new?

Regards

Mention : after I start the machine in the short time when this code appear the drum is full with toner even if I clean it before. Thanks for your support I'm amazed and grateful about your quick response

certinproject if the drum is full of toner and your getting sc302 then you have no charge. If all seems ok in the pcu area try cleaning or replacing the charge roller although i've never had this error from a bad charge roller before just PCQ. Again as previously mentioned check the metal contacts on either side of the charge roller making sure they're not bent. then try a HV power supply, again never had one gone down before my self. hope this helps, good luck

If I start the machine with the high voltage supply board disconnect from the main board the machine have a normal start and SC302 appear after I try to do a copy. I think I have this board defective. Where I can find to buy this board? this code is stick on the board: 3Z240268 . I don/t have manual for this machine. If somebody know something or have this board even if is second hand and used please give me a sign.( I don't wanna be out of tread) With thanks .
