1 - Direct PCB Conversion - Opening the D78


Opening the D78 printer is quite easy. First, remove the two screws at the rear.





Then, starting at the back of the printer, working round clockwise, release the 6 clips. The first one is easy - Just press it in and lever the case up slightly.


The second clip is also easy. Press a flat bladed screwdriver up slightly into the slot, while providing some upward force on the case.


The next clip gets slightly trickier. This is the internal view of the right hand version looking down through the case.


Epson has made this rather difficult with these clips. Your aim here is to press outward on the bottom plastic, while pressing inward on the top plastic, at the point of the clip. Once you've applied enough force, it should just pop out!


In the center of the paper tray at the front, you need to press in on the bottom plastic, while lifting the top plastic.


The following two clips are repeats of ones you have seen before. However, this time you can get access to the clip itsself by moving the print cartridge to the center of it's carriage.




Move the print head back to the park position.

Back at the other side, this is the last clip you need to undo.


Now, the body shell should just be able to slide off the printer vertically.
