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
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).
Step 2: Removing the Keypad and Keypad Harness
Note the "hook-like" plastic tab and plastic nub (that locks into the tab) below the lcd panel and to the left of my dirty finger (sorry -- from oil change to scanner repair man). Push the tab up and slide the keypad to the left.
Now, gently pull straight up and locate the ribbon harness. Gently pull the ribbon harness out of the keypad. The plastic holder stays in place. Only the ribbon can be removed. Set the keypad aside.
