    I do the same and there are some amazing parts to be found.

    If it's not nailed down, it's mine.
    If I can pry it loose, it's not nailed down.

    2muchstuff,
    If you have any pics post them and if possible the brand of copier, I like to see what's out there.

    Zumba,
    I suspect if you check in your area for copier repair centers they will have a pile out back ready for dumping and they will have no problem with you stripping them once you do not leave a mess, this will keep the police of your back as well as Kinko's security . Remember to search throughly as I almost missed 2 steppers on each copier that were hiding behind a circuit board.


    Each copier seems to have one really large transformer and a smaller one along with an interesting looking lead screw. DC brushless 24v fans are to be found as well. The skate bearings (608) do not seem to be as numerous on these newer copiers. I will brave the sun for a few hours today to liberate some more parts but at 600 lbs a piece they do not like being moved around too much.

    Pics to follow.

    Jason

    Jason can you please do us all a favour and post just a few photos of the kind of copiers that might contain those rather large (1.5A+?) steppers so we know what to look for? Does it have to be one of them '80s tank-size copiers or your ordinary everyday A4/A3 desk-size copier?

    These copiers are about 3 feet tall and weigh 600 lbs. The Toshiba series numbers are: 7550, 6560, 6560, 5540.

    The only desktop machine I know to carry a reasonably strong motor is the HP laserjet 3 which carries a 100 oz/inch motor.

    A few pics of other items recovered including heat sinks, transformers, leadscrew, bearings, dc brushless fans, solid state relays and drive belts. These were recovered from one copier.

    It seems that I was a little luckier than I originally thought as I discovered that at least some of the Minebea motors have a 1/4" (6.35mm) shaft instead of a 6.00mm shaft which allows me to use the lovejoy couplers I already have . Finding a vendor that sells the Lovejoy L-050 series coupler with a 6.00 mm hole is a pain.

    I frequent several copier repair places. The ones that get trashed are no one particular brand, they are the traded in ones from new purchases. The machines range from the small desktop to commercial laser magnetic ink type. Talk to someone in back like a warehouse person, people up front are useless so are sales people. Get there permission and get it wrote on their buisness card. That way when diving after hours in the dark and the cops show up you are covered. You may be wondering how I know this, experience. Get to talking to the guys and you may find out when they are getting ready to bring in a 40 yarder, parts galore. Most places don't care about you diving as long as you don't make a mess, it saves them space in thier dumpster as you take the parts.

    If it's not nailed down, it's mine.

    I went to the Toshiba boss who was happy to get them from the back of his office. I usually take all they have to dump and end up with a load of parts . Occasionally you will end up with a machine using 5 phase motors as the main motor but this has not been the case on my last two trips. Hopefully someone comes up with a cheap hobby 5 phase controller so that the ones I have had here for a while will be of more use than a paperweight.

    Jason,

    I noticed you haven't popped the hood off of the ADF (Automatic Document Feeder) in the picture you posted. There is usually a good sized stepper motor under there that drives the feed belt.

    Happy hunting,

    HayTay

    Hi Harry,

    That's normally the case Harry but Toshiba uses a small servo type setup to run that section. I will take that pic and post it later today.

    I never pass up a document feeder. Most times there is a nice sized PM DC motor and belts in them that I use for my RC boats.

    If it's not nailed down, it's mine.
