Service Tip - Most Machines - Feed Rollers

Hi Guys,
I just wanted to pass along my best feed roll tip.
I got this from an engineer many moons ago.
Once you clean the rollers with alcohol, take a drop or two of oil and rub it into the rubber.
After a bit, you will notice that your rollers now have a huge amount of grip.
The explanation was that if it is a Japanese box, then it uses synthetic rubber rollers which age differently from natural rubber rollers.
Just for grins and giggles, try it on the ADF feed and pick-up rollers for a test.
This works on most of the grey and black rollers. On really new machines I have been seeing these new type, kind of clear looking rollers. With these, it does not seem to work as well but I do not have enough boxes out there to test with any certainty
I use Castrol 5W-50 Synthetic.
It does seem counter-intuitive but give it a try.

wd-40

I use wd-40 on feed separation and pick up. Works great. No alcohol. Ever heard anything about rainx on radf slit glass?

Alcohol dries out rubber.

Absolutely. And if all you did were to wipe down the rollers with alcohol, yep, you dry them out. If you follow up with the second step, you will find that the rubber absorbs the oil and the rollers don't dry out.

I love Rain-X. And not just for my car. After cleaning the slit glass, I apply a few drops and begin to work it in. At first it is very liquid, but over time it thickens and coats. Let it dry and remove the residue with a damp cloth. The layer it provides resists anything sticking to the glass and what does, like white-out, is super easy to remove. Also, I apply it to the surfaces of the photo sensors. Once done, polish them with a q-tip. Their surface is now so slick that dirt and crud does not adhere. And anything that does is easily blown off with canned air or a puffer brush.

Adding oil to rubber is a very old trick, I used to service IBM typebar typewriters that had a power roll, the shoes for the typebars would contact the rubber power roll and after a while would slip. We would clean roller with trichloethane and then oil it. The rubber absorbes oil and expands a little and becomes grabby again. My tip is never use motor oil on plastic bushings, guides etc. because it will make it expand slightly and break the plastic down...use silicone oil

Hence the saying "All that is old becomes new again".
