I have an MP 4002 that keeps giving me error codes. The codes are SC 360 and SC 372. I have done a complete PM on the drum unit with new developer/drum/charge/blade after cleaning it out really good and when I was still getting the error I threw in a new development unit with another fresh batch of developer to still get the same error popping up when trying to perform SP 2801. Not really sure what to try now. Any help would be much appreciated. Thanks
