This is instructions on how to disassemble the top portion (scanner and Document Feed) of an HP Laserjet 3030.
The problem: Photo scans were having streaks in the image.
Cause: Wires connected to the scanner element dragging across the glass - these wires appear to be coated with some sort of light lubricant
Solution: Disassemble -- clean glass
T-10 Torx Bit <--- if you're buying a torx set, I recommend that you buy a tamper evident set just in case you need that feature later ;)
Awl or something with a pointy edge
Glass Cleaner and chamois
Step 1: Remove Screws and Keypad Cover
Turn off and unplug your machine ;)
There are 5 T-10 torx screws that need to be removed -- see photo notes below. Remove them and store in a safe place.
The keypad cover is held in by friction and several tabs located at the top of the pad. Pry from the bottom of the cover and lift straight up. When the pad releases - pull up and away (towards your body) and guide the keypad off.
You'll notice that my machine is still on at this time. I was hoping I would not need to remove anything wire harnesses and keep the machine running while I did the fix (my parent's business needs this machine up to receive faxes).
