When I try to enter a number in my my HP officejet pro 8600 it will try to put # while typing
The display on machine On my HP officejet pro 8600 plus printer is acting like a button is stuck.the display is going crazy with the # and 9. like its stuck but its digital. It did it all day yesterday & today. Tried turning off & unplugging. When you do try to enter a number it will try to put # while your typing.
