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


Tools
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
Rubbing Alcohol
