How does a subcontractor release a mechanics lien in Oreagon after the debt has been paid?

I'm a property owner that had several subs not get paid by our contractor and filed liens. Liens are all paid now and I have 1 sub that does not know how to remove the lien and asked if I could provide him the paperwork so we could turn it in to remove the lien. Do you have full sanctification of mechanics lien I could access? Thanks
