Shelf life of Riso ink

[ianmck]

Does anyone know how long Riso ink can be stored for and still be useable? If the model matters it is for a GR3750. Can ink that is too old damage a drum?

Thanks.

Re: Shelf life of Riso ink

Depends on the brand. I have had ink separate after a couple of years and that was oem. I use non oem and had no problems after a year. The only damage would be if it separated and the fluid dripped into the drum. You can easily tell when it is separated by looking at the tube.

Re: Shelf life of Riso ink

Riso stamps the year and month of manufacture on it. Any tubes from before this time we won't use. 2 years max is our cutoff date in a good environment. Using old ink will just make for slower dry time and more ink getting in places you don't want it to in the drum.
