can't get rid of SC 352 codes; replaced ID sensor twice;2nd ID sensor I replaced today allowed me to get SP3001 to set without error code; however after about 20 copies SC 304 followed by SC 352 came up. Another thing I notice is when copier is shut down the powered back up copies are light and SP 2001 has changed. Could this be an NVRAM problem???
Thanks!!!
I think SC 304 is the key to the problem. Both codes relate to drum charge, possible over toning and possible coated development (mag) roller. If you do not currently have a copy of Goose's Guide, download it and follow the trouble shooting steps it lists.
Kill it and replace it!!!!!!!!!!!!!!!!!!!!!!!!!!

Check the charge roller , I think bushings are dirty and preventing it from moving
^^This was what worked for me the last time I saw an SC304.
I keep getting 304 on an MP4000, i cleaned the charge roller, contacts and bushings then developer and mag roller were replaced. cleaned ID sensor and reinitialised.
Still get the SC304 coming in on @remote, but no issues on CQ.
So yer, we've abandoned hope until the CQ goes downhill.
