HP OfficeJet 6310 all-in-one printer hidden functions

Recently one of the HP 6310 printer had a problem and I had to call up HP Support to get it solved.

In doing this I got to learn some new functions that can be used in this printer.

1. Reset the printer settings
Unplug the printer from power. And then wait for about 1 min for the power to be totally drained out of the printer. And then press and hold onto # and 3 buttons on the number pad on the printer and then plug in the power cable while keep on pressing the # and 3 buttons. Now wait till a message comes up on the printer display. Normally this will come up with Language selection.

2. Service Menu
While the printer is fully powered on and it is in standby mode. press * and # button together. This will show a message on the display of the printer similar to this "********########" . once you get this message key in the following number in sequence using the number pad 329. Once you done that a message will come on the display saying "Service" and a number. Now using the arrow buttons you can browse trough all the available menu options.

Hope this will help people who want to do troubleshooting on there printer.
