 +===== 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).

 +Caution: invalid backup GPT header, but valid main header; regenerating
 +backup header from main header.
 +
 +Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
 +on the recovery & transformation menu to examine the two tables.
 +
 +Warning! One or more CRCs don't match. You should repair the disk!
