    [Misc] sensors and wires

    hi every one
    first : i want to know the arrangement of sensor 3 pine
    which one GROUND , 5V DC , and signal
    if there any picture will be beter
    second : table that appear the wires' color related it's voltage in canon
    i mean if the wires' color is red >>>>> that mean the volatage is 24 v dc and so>>
    thanks alot

      Re: sensors and wires

      Naturally, if you had a specific sensor in mind, my answer would be more specific, but here goes:

      Most of the photointerrupters I see these days are 5vdc, but in the past I have seen photointerrupters that use 5, 12, -12, and 24vdc. We'll talk about 5vdc photointerrupters.

      Canon stopped color coding their wire harnesses 20 years ago when the ir2200 came out with the miles and miles of purple wire. Perhaps 20 years ago you could rely on wiring color conventions, but that has gone out the window. For 5vdc it's supposed to be orange.

      To check a live photointerrupter, use your meter and read the voltage at the outer pin to frame ground, then the other outer pin to frame ground. One of those pins will be +5vdc and one will be frame ground +0vdc. Now connect your meter to the signal pin (center pin on the photointerrupter) and 0 ground. Blocking the photointerrupter should give you a change ~5vdc to ~0.5, for a good working photointerrupter.

      Keep in mind that photointerrupters in areas of high heat (like near the fuser), can become intermittent when the temperature is high, but work normally at low temperatures.

      How's that for a nice general answer to a nice general question? =^..^=
      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.

              Did my old eyes miss it or did he not mention what copier he's working on?

                  Well it came in under the Canon forum, so I leaned my answer in that direction, but no, there was no specific mention of a model, or any specific sensor, or even a general type of sensor. General question leads to general answer. =^..^=
