Question about Canon PIXMA iP4300 InkJet Photo Printer
Yahoo_or mistakenly writes that there are five slots to release. There are, in fact, six, but only four have arrows (two on the side, two in the back). There are two more plastic "locks" (for lack of a better term) that you need to release in order to remove the top cover. Khumbu describes their location in an earlier post (poorly titled "wont print") here: http://www.fixya.com/support/t188220-wont_print
In his article, Khumbu describes two additional release holes on the bottom of the printer, near the front (note that the holes are the second to the front, immediately behind the ones closest to the front); these probably correspond to the "two flat vertical pieces" that yahoo_or mentions above. Be sure to use a long, narrow flat blade (i.e. a standard flathead screwdriver) to push the each tab toward the side of the printer to release each hook.
Once all six "locks" are released, the cover should lift straight off relatively easily.
Putting the cover back on is a little tricky. You need to make sure the control panel is properly seated and that the plastic pieces such as the silver plastic corner with the power button and the other silver plastic corner piece are properly snapped into place. Note that there's also a black plastic USB cover in the back that might come loose because it's not fastened down; make sure it's properly positioned. Carefully lower the cover straight down and make sure the corner pieces and release hooks mentioned earlier are all lined up properly. When everything is properly positioned and seated, the cover should snap back on all around. It may take some fiddling (not the musical kind). Enjoy.
One plus to this adventure was that I found my old soldering pencil. Yippie.

The problem is that the ridiculously cheap little plastic piece on the door hinge that is supposed to trip the switch that tells the printer that the door is open is either a) broken off or b) no longer aligned so that it pushes the switch all the way. I solved the problem by removing the top cover and gluing the switch open with super glue.
To open the cover, find yourself a small, flat piece of metal (or stiff plastic) about 1/2" wide and a few millimeters thick. (A very flat-bladed screwdriver will do, but I made myself one out of the non-sharp side of a straight-edge razor blade.) Push this into the 5 slots marked with an arrow around the sides and back of the printer (they're toward the bottom of the sides.) Pry up on the cover at the back and then pull straight up on the front. There are two flat vertical pieces that slide into slots at the front that have to come up - they were tough to make come loose, just try not to break them off.
Pick up the electronic control panel that is on the front right of the printer. (You might have to remove the silver piece of plastic at the right front corner. It pulls straight up to remove.) The switch is the little black plastic piece on the left side of the electronic control panel. Push it to the "open" position (opposite the resting position) and glue it in place. Reassemble your printer and voila! no more annoying "door closed" message!

I looked at the previous posts and got the cover off. Then I tied a string around the lever, pulled it up and tied it up at the top. I love low tech jury rigged solutions. Cheers.
