Remove the power button circuit board from the support frame by pinching the left side, and pulling forward and to the left simultaneously.
Push up on the tab holding the secondary control circuit board with the spudger and pull it forward to remove it.
Be careful not to pull too hard on the cable connecting the power button control circuit board and the secondary control circuit board to the main circuit board
Remove the printer head cleaner by lifting the front of the printer head cleaner above the track and slide it forward.
This is an extremely difficult step. It can take quite a bit of force to lift the printer head cleaner above the track and it is easy to slip and hurt yourself.
i got everything taken apart and fix my problem but now i cannot get the printer head cleaner gear to set in place and work like it supposed to. any advise?
Beautiful description, thank you. I disassembled the printer, cleaned everything thourouly and put everything back, but I realized that the feed roller is stuck. I don't know which step went wrong. Any suggestions?
The HP Photosmart c4580 has enough in common with this model that this guide enabled me to get into the head cleaner reservoir and remove the years of accumulated ink gumming up the works - thanks!
