Disassembly Instructions for HP Deskjet Printersby Ty Arthur
Your HP Deskjet series printer has a wide range of internal components that may go out during the life of the machine. Whether a specific defective part needs to be swapped out or you just want to see how the printer works, there are many reasons why you might want to disassemble the unit. Completely taking apart a Deskjet printer is a fairly complex job, but it shouldn't prove too difficult for anyone with basic experience in taking apart computers or electronics devices.
Lift up the Deskjet's top plastic cover and wait for the ink cartridge carriage to slide out from the left side. Pull up the two ink cartridge covers and remove the ink cartridges.
Leave the top cover open and unplug the Deskjet's power cable. Disconnect the USB cable. Locate the four locking screws on the top-left and top-right sides of the Deskjet.
Remove the screws with a hex screwdriver and pull the top half of the case off the Deksjet printer. Remove the screw on the left side of the button control panel and pull the panel off the printer.
Locate the thin, green plastic ink absorber at the bottom of the printer's case. Pull the absorber toward you and lift it out of the Deskjet.
Remove the screw holding the printed circuit board in place at the right end of the Deskjet. Pull the circuit board out of the printer.
Remove the screws at the left and right ends of the ink carriage and pull the carriage out of the printer. Turn the printer around so the back end is facing you.
Push in the visible plastic latches and pull apart the top and bottom halves of the plastic casing and finish disassembling the HP Deskjet printer.
- The printed circuit board will be damaged if you accidentally discharge static electricity from your hands. If you intend to put the HP Deskjet back together, you need to ground yourself before beginning the disassembly process. Tap your hands against an unpainted metal object connected to the floor to release the static electricity.
- Individual Deskjet printer components are available both directly through HP and through third-party online printer parts retailers.
