Get the driver from me.
When I first bought this printer there was no 64 bit windows driver. Then, for a brief period of time there was a 64 bit driver for Vista offered at the Sharp USA website(which works for 7 and 10)...but after a mere few months this window (no pun intended) of opportunity vanished leaving only the 32 bit version available again. NOW the entire driver page for this model on the sharpusa.com website has been "archived", however, when I try and visit the archived page the site claims to be experiencing "technical difficulties", and to try again later. This has been like this for almost a year now.
Fortunately I was able to find the 64 bit driver on an old hard drive so I have the elusive 64 bit driver again for Vista, 7 and 10.
I just uploaded the driver files to a file cloud. I had to cut the driver files .zip folder into 2 so I could meet the file size requirements of my free file hosting service. Make sure to download files from both links and read the README files I wrote so that you can re-assemble the original file structure:http://http://
