Thank you, thank you, thank you!!!!!!!!! This worked. My printer has been stuck for two years now. Decided to pull it out today and give it one last try, found your instructions and it works again!!!!!
For anyone else using this fix you can get 64.59.11 (Bridge Release) here https://www.support.xerox.com/en-us/product/phaser-6510/content/147727?language=en&platform=win10x64
Nice to hear !
I also strongly recommend to further upgrade your firmware to v 64.68.31 even if your Phaser 6510 may already work fine with 64.59.11. The version 64.59.11(as well as the previous) may produce a memory mgmt issue in some conditions. Enjoy !
