ive got a couple of these, mainly tray sensors,clud, dlud, also ppd2. tray sensors show no paper in tray, motor dont lift. swap motors out all ok. what kills them. ppd2 is reflection sensor, have cleaned before. static?

Re: 363/453/503 sensor dead
Great question. I've noticed these sensor failures on Sharp and Toshiba. Most of the sensors that I've had to replace were of the Sharp "73" variety.
A couple of the machines in question had dirty power, but certainly not all. I've come to distrust the sensor test service modes. The only definitive test is connecting meter leads to the center (output lead) and ground, and watch the output (0-5vdc).
My guess is that there is some sort of quality control problem in manufacture of these sensors. I've replaced perhaps 4 dozen of these sensors in the last 2 years, and perhaps a dozen total for the previous 23 years.
You may care to try an experiment. The next time you come across one of these sensors acting up, while it's still live unplug the connector and plug it back in. A couple have resumed function, but I still didn't trust them to continue to work. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: 363/453/503 sensor dead
Here is a bulletin regarding it, MFP-TB-1025.
I have tried to swap them around and was not successful. The best you could do is to swap to make it less of a problem for the client and to order new sensors. I have replaced many of them between PF and DF.
The problems stems across several copier lines. The bulletin will show how to possible get reimbursed for the time and energy spent on the sensors.Comment
