I have Windows 7 Professional on a desktop computer, and a HP Office Jet Pro 8100 printer equipped with a duplexer.
Since purchase some 18 months ago the printer has been working flawlessly. Now, the duplexer has stopped working. I have removed the attachment and reinstalled it, and removed and reinstalled the software, but the problem remains. I have only one-side printing.
A couple of weeks ago I printed some photographs and had to turn off the duplexer via "settings" for the printer, because it wanted to run the photo paper front and back. After that I returned to "settings" and turned the duplexer back on. It worked normally for a few days and then quit printing front and back. When I look at "settings" it shows the duplexer installed.
What next? Could the accessory be going bad?
Thanks, stowerssf
