Okay I had a paper jam and removed the paper. Now I have a Code 318 error that I cannot get rid of. There have not been any recent posts on the OKI forums so wondering how much help if any, I can get. I have tried everything to correct. One thing is states is to check the sensor lever of the WR sensor. What is the WR sensor and where is it located? What does WR stand for? The problem is not in the fuser or cartridge assembly. Sure wish I could fix because I hate to purchase a new printer right now. Has anyone had any experience with my type of problem before on this printer? Sure wish I could get in contact with someone who really knows this printer. Lee
