lots of problems for this discusssion. These machines tend to be real sensitive about developer settings and too much messing around with the ATDC sensor settings just tends to make them worse.
Try replacing the developer first. The ATDC sensors go bad a lot on these too.
All the other problems need more details to troubleshoot
