We've got an Epson Expression 1640XL scanner that we'd like to disassemble to clean because of a speck of dust on the image sensor.
I've got the screws off the back, and the plastic carriage lock removed, but I am only able to lift the top casing very slightly (maybe 1 inch) on the back side of the scanner. There are two (of what look like) pressure clips on the right side of the scanner glass, and the rear-most one is released, but I cannot release the front one, nor figure out what else needs to be done to release the top casing.
I can take pics if it will help, but any tips would be appreciated!!
