    Canon Cadmium Sulfide Photo-receptor

    I was reading and found that Canon's photo-receptor is composed of Cadmium Sulfide (or at least at one time it was). I seem to remember someone telling me a very long time ago that Minolta's photo-receptor was also made of the same material.

    I remember seeing one in a vintage machine and the color was something like "School Bus" yellow or maybe a bit more brown in color.

      Yeah they were yellow, I polished many CDS drums. This "dangerous" chemical was very popular for drums back in the day. I guess it had the characteristics to charge / discharge, etc. Disposal was strict if I remember. Years later they say exposure is bad. I guess us old timers would be dead by now if they didn't switch to organic drums

          That goes back 30 years. The last Cadmium drum I saw was in 1990.
          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.

              Cadmium was also used in metal plating. There apparently were many antique radio chassis plated with Cadmium which turns to a whitish crystalline powder of the course decades. Nasty stuff to breath.

                  Operation LAC (Large Area Coverage) was a U.S. Army Chemical Corps operation which dispersed microscopic zinc cadmium sulfide (ZnCdS) particles over much of the United States. The purpose was to determine the dispersion and geographic range of biological or chemical agents.

                      Nice....

                      Yeah I heard they are going to make a giant country size photocopier.
                      Next chemical spayed in the atmosphere should be DDT to defoliate the all the trees; ready to pulp the entire forests into a giant sheet of paper.
                      After that we should be able to harvest chlorella spirulina (smelly pond scum that grows under water) to use as toner on the giant sheet of paper.

                      Anyone for Rice paper and Chlorella for dinner... Yum... not!....

                      Way to go...one lie is the same as the next.
                      Why didn't they just ask the apiarists(bee keepers)?
                      Seems USA buys tonnes of queen bees from other countries each year.
                      I wonder why that is? Seems bees are the biological interdispersent miner canaries.
