    These aren't the worst fusers ever made ... but they rarely make yield, and I've had quite a few that the gear separates from the sleeve, then blows the thermostat. The replacements with the black glue are supposed to be better. I have not seen any of those separate ... yet. =^..^=

    I just pour all the oil inside the belt and slide the belt into the belt holder by rotating the belt in the paper feed direction and gently push the thermistors when the edge of the belt reach them, no oil mess at all and no extra hands needed. Tried different ways but this is the best for me so far.

    Firstly I recommend virgin sacrifice to the great god of Xerograph.

    I have always gotten used to wearing gloves since the gold corona wire days, I like the blue neoprene ones.
    While it takes care of your paws from getting oily, it does nothing for your tools.

    This fuser design is stupid.

    I pour a thin line along the sheet, full in what I can and still hold the innards along the pressure pads recesses then fit the sleeve about half way to then dump in all the rest of the oil and slip/spin on the remainder of the sheet.
    It's gotten to the point where we try and have a second tech on hand to assist as is seems to need 3 hands to do and not dork up the fragile thermistors.

    How do you install these frustrating fuser sleeves?

    from another thread:

    And use the oil. It's necessary. And it's very easy to damage the thermistors. I start the sleeve onto the holder, wipe oil onto the first 75mm of the teflon sheet, then carefully rotate the sleeve while sliding it onto the holder. As you near the thermistors press them back to slide the sleeve past. Apply more oil, repeat ... Don't forget to move the bearing from the gear side of the old sleeve to the gear side of the new sleeve. Your hands will stay nice and slippery. Plan on dropping your tools frequently for the next few days.
    I've tried a few ways, including above, but its just messy. There is probably no way to eliminate the mess, but there must be a better way....

    When I went to training, the instructor show a short video of how they do it in Japan. The video showed a very Asian fellow (with a hair net on), and he poured all the oil into the sleeve (non gear end) and held it for a while, I'm assuming so that the oil runs the whole length of the sleeve. Then the sleeve was slid on to the holder.

    First time I tried this, I made just as much mess as any other method. Then I noticed on the holder, there is an area between the Teflon sheet and the the sliver spring holder (away from the thermisters) that is recessed. If you orient the oil line inside the sleeve to line up with that recess, the mess is less, and the more of the oil stays inside. I immediately rotate the sleeve so that the oil rubs right on to the Teflon sheet, where I believe it belongs.

    Any other input or methods to help this? I mean I don't mind dirty hands, but oily is just plain awful. Oh, beware of the thermisters. If they become damaged, you have to replace the whole inside holder.
Working...
