How to Add Oil Back to Your phaser maintenance roller: Counter

Adding oil and what type:

The method I give here is not under the counter general warranty. Neither will I assume any liability or responsibility for your printer if you use this technique. Although I've had good results and recommend that this method for reusing your old rollers along with a purchased maintenance counter if you decide to add oil then you must proceed at your own risk, as I have done research but I don't claim to be an expert on the lubricating fluid inside these rollers. That said I've personally printed over 100,000 prints with good quality and good results and no damage to my print engine

Studying the Tektronix patents gives a good clue on the type of oil inside these maintenance rollers, basically its simply silicone oil. The hard part is determining what the correct viscosity should be for the replacement oil. After some basic research I've determined that Genuine Xerox 8R2955 fuser oil is the correct replenishing oil, given the porosity of the sponge roller and the required mg of oil deposit on the fuser drum. You can usually pick a 1 liter bottle of this up on ebay for as little as $30.00 (including shipping). A liter will give you 6-8 refills of your old sponge roller.

The basic method of adding this silicone oil back to the sponge rubber is simple enough. You should get a plastic tray large enough to easily fit the maintenance roller and I'd recommend rubber gloves. As far as the rubber gloves its not that the oil is dangerous, as the MSDS shows its very safe, but this oil is really hard to get off the skin or for that matter any other object (even detergent isn't that effective). Also I'm the kind of guy who likes to error on the side of caution. Now take the steel rod out of the roller and pour approximately 10 tablespoons amounts into the tray. Work this into the roller on all sides with your gloved hands and do this until no more oil can be asborbed (saturated) by the roller. These rollers can absorb up to four times their weight in oil, so don't get skimpy adding oil. When no more oil will go into the roller take a dry paper towel and wipe the surface of the roller and reassemble back into your maintenance tray.

Only do this step if your roller has excessive ink deposits:

As far as ink striping the surface of the roller, I've found that this usually happens if the roller gets too dry of oil. As you probably would agree the more lubricated the oil roller the less likely the wax ink will stick to its surface. But yes the surface of the roller can be gently cleaned of ink striping. I've found that before adding new silicone oil as in the above paragraph that I could gently clean the roller with soapy warm water and a slight working with my gloved hand to remove most of the striping. It's a fine balance between washing and rubbing and not scouring the surface of the roller. I suppose its best to stay away from using the gorilla finger approach if I were to describe the amount of persistence and force required to clean a dirty roller of excessive ink. Obviously if you dig a hole into the surface of the roller cleaning the ink off it you aren't going to have a good roller when done. But still it takes a bit of rubbing to get mostly clean, and you won't get something perfectly white and shiny so don't even try. After that laborious cleaning you'll want to rinse and rinse until no more soap bubbles come out. Since my water isn't hard I really don't worry about a final rinse with distilled or deionized water, but you might consider otherwise as a final water rinse out. Finally after water washing you'll need to let it completely dry in warm and sun for a good week before adding back the silicone oil as mentioned above.
