Hi everyone, I'm looking for a service manual for the HP Officejet H470. I am trying to remove the top cover (the section above the silver strip). I am currently unable to do this. I have removed the 8 obvious Torx screws including the 4 screws underneath the rubber covers. I have also unclipped the 3 internal clips I have been able to access however the cover still wont budge. Thanks for your help.
