 +===== Reset HP OfficeJet Pro 8600 Plus ===== 
 +<code> 
 +My printer is a N911n, and I have not found a consistent way to reset it. 
 +I did get the Home, Back, Home, Home to work possibly one time a couple months ago, so not sure if the Oct 31st firmware changed something, 
 +as I have not been able to do any kind of reset.   
 +(tried the Back x 4-5 times as well at boot up, but nothing happens, after power off/unplugging for 1-10 mins).
