    HP CM4540 doc feeder light green/on from boot

    No paper in doc feeder and green light stays on. The problem stays with the printer frame. Have switched with another machine (doc feed assemble, doc feeder PCB, formatter, updated firmware and cold reset). Any ideas? paper present flag checks out fine.

    Re: HP CM4540 doc feeder light green/on from boot

    If you press copy does the df try to feed? Just wandering if the machine is actually recognizing it being installed. If it does, then the df paper detect sensor is not changing, from High to low. I think that's a photo-interrupter? for what ever reason. If not then I am not sure where to go... Power supply?

    Good luck and let us know what happens.

    If you have another machine to swap with, try swapping the entire scan assembly. I can't remember, but it seems to me that the doc feed hooks up to the scan assembly, which hooks up to the actual machine.
