The best way to get a stripped screw out is to improve friction with a rubber band or an abrasive like steel wool. Using a larger screwdriver can be helpful. With a cross-shaped Phillips head screw, turning with a flat-head screwdriver provides added grip.
To remove a stripped screw from plastic, it`s best to use a gentle method—plastic is softer than wood or metal and can be damaged more easily. Before using pliers or hammering the screw to create new notches, try using the rubber band, hot glue, or duct tape methods.
Try adding a dab of superglue to the top of the screw. Set your driver into the screw head, and allow the glue to dry. Using a firm grip and downward pressure, give the driver a twist to remove the screw. Don`t forget to clean the remains of the glue from the tip of your driver.
You can unscrew a stripped screw using a rubber band, pliers, a drill or even a screwdriver. When figuring out how to fix a stripped screw, remember to not overwork the screw with any one method. If one fix doesn`t work, quickly try another. You don`t want to strip your screw any more than it already is.
Use a Hammer

Another way to help you get some traction with your stripped screw is to use a hammer to gently tap the handle of a manual screwdriver deeper into the stripped screw.

Fortunately a little cyanoacrylate (CA) glue fixes them just as easily. Simply fill the stripped hole with CA glue, let it cure for a couple minutes, and re-install the screw. It works for any size screw and any type of wood.

I need access to the strip and carrier
ANSWER : Nothing available in the way of diagrams. Basically, that is an encoder strip. It slides through a U shaped plastic sensor in the carrier. If it came out, then you can use a mirror and flashlight to try and thread it through. Then you hook the rectangular hole at each end of the strip onto the 2 metal hooks on the sides of the printer. You can find them by stretching out the strip and where the end points is where the hook goes. One of them is spring loaded to keep the strip taut. Without the strip, the printer can’t see the position of the ink cartridges. Way too much trouble to disassemble that printer.
