I have been working with a Toshiba eStudio 233 that gives a e550 jam code after feeding one sheet of paper from either tray. After paper exits into output tray, machine continues to run with no paper being picked from tray and then will stop and give e550 code. There will be no paper in path. I only need to open and close access door below bypass unit to reset machine, and cycle begins again. New feed tires were installed earlier this year and feed side was disassembled two days ago, all sensors in path cleaned and reassembled with good results for 2 days. It has been awhile since I have seen this on a Toshiba and I need a memory refresher. Thanks for any ideas on this issue.

Re: eStudio 233 e550 jams
Hi: Your problem is caused by a failing sensor located on the bottom of the bypass unit. Remove the duplex door then remove the bypass unit. Flip the bypass unit over and remove the black access cover that covers the sensor and replace it. It's a common problem on that series.
