IBM Colo 8 fuser roller got fouled with a sticky residue from inkjet photo paper. The sticky substance has a paper coating and is difficult to scrape from the roller without doing damage to the rubber roller. I've read posts suggesting lighter fluid, silicone oil, and fuser oil as possible solvents. A glue remover would seem to work great but I think it will damage the rubber roller. What is the best solvent for cleaning the rubberized fuser roller?

Cleaning web is a prediatecally replaceble part.,its a part of fuser assembly which cleans the fuser roller surface and applies lubricarion to avoid ghost image, toner stains, paper jams. Its look like a paper roller very near to fuser roller depends on model.
No fusing part in inkjet technology printers. Laser printers only having this part to bonds the image on paper. The fuser contains main parts of heater, teflon sleeve & pressure roller. Fuser produces the heat & fix the image on paper with the help of teflon sleeve and pressure roller.Ideal Image of fuser internal parts:
It sounds like the problem is either on the fuser or the drum of the toner cartridge itself. Take the fuser out from the back by pinching the two levers on the left and right side and look at the fuser itself, you should find some type of residue on the film of the fuser, if thats the case your best bet is to do a refurb exchange on the fuser. Also, rotote the gears to inspect the circumference of the fuser roller.
if you dont see anything there, then check the drum.
I'm assuming that the cracking noise occurs as the printed page is passing through the fuser?
Check your print settings to ensure that your paper stock is not set to heavy (card). This setting applies extra heat to the fuser to 'fuse' the text to the paper, which is what you want for card, but if you are printing normal stock, it will overheat the toner causing it to stick to the fuser roller on the way through and make a 'cracking' sound as the paper peels off the roller.
Whilst it is possible that there is a fault with the thermostat and the fuser heater is not switching off, this is rare. If you have been printing a number of pages at an incorrect paper stock setting you may need to clean baked text of the upper fuser roller, in which case, apply the following procedure.
After switching off the pirnter and it has had time to cool you may be able to clean the upper fuser roller with a rag moistened with a little methylated spirit, although you will not be able to rotate the roller fully without removing the fuser assembly from the printer. If the roller is physically damaged however, eg. scoured, cleaning will not resolve the problem, the roller will need to be replaced. This usually occurs after a long life, so it is generally best to install a new or reconditioned fuser (includes new rollers, top and bottom and new heat lamp).
There are two factors. One is that the fuser (hot) rollers get contaminated with toner residue, resulting in them getting sticky. The sheet sticks to the roller, and instead of being fed straight through, it gets bent with the direction of roller rotation, and is pushed under the separator pieces. The second is that the separator "tongues", that should facilitate separating the sheet from the roller and directing the paper to the output, deteriorate over time. They are plastic, and subject to prolonged heat, so after some time they tend to lose their shape, get cracky etc.
Replacing the fuser is not a hard task, OKI is rather modular in it's construction. The instructions should come with the new fuser unit, and also you can look for directions on OKI website.
If the fuser heater were defective, you would probably get an error message related to fuser temperature. It may be that there is some residual toner stuck on the fuser roller and it causes the paper to jam. It may also be the other roller in the fuser that is worn. Don't worry too much about resistances; they are relative.
the lubrication for the fuser roller comes from the KM toner. There is usually a cleaning roller in the fuser as well that distributes some oil. Another thing that could cause the problem is non-recommended paper like heat transfer paper, inkjet photo paper or very thick paper. Make sure the fuser sperator teeth are still in place. Lift the two green levers and pull the black cover back. You should see three light brown teeth hovering above the fuser roller. There are some black ones on the guide as well. These are supposed to detatch the paper from the roller incase it sticks.
