    This works on every photointerrupter:

    Leave it plugged into the copier and powered ON. Use you're meter on 5vdc range. Meter each pin to frame ground. There are (3) pins:

    ground: 0.0vdc
    supply voltage: 5.0vdc
    output: 0.2 to 5.0vdc, depending if the sensor is blocked or unblocked

    Simple! =^..^=
    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.

    Be aware, a photo sensor may appear to function correctly in a static test, removed from machine, and still be defective. Many fail dynamically due to hysteresis caused by age. It only takes a couple of milliseconds delay to generate a jam detect.

    Re: Test AW020145-PHOTOENTERRUPTOR.

    I was able to test and the problem was even the sensor, I used a part of his idea and I got another sensor, but I mounted a small electrical scheme, to identify even when it is the infrared emitter that are burned, looking at the camera of the cell phone or when the problem is in the phototransistor, through a resistive divider that generates pulses when a barrier is present. Many thanks to all for the help.
