Replacing the side cover
After installing the memory, you then replace the side cover on the printer
and fasten it with the Phillips screws that you removed earlier.
To replace the cover on the printer, follow these steps.
1
Line up the front edge of the side cover with the front edge of the printer.
2
Gently press the cover into the printer until the tabs snap into their receiving slots.
Check the Phillips screw holes on the back of the printer. The holes should
be unobstructed. (You shouldn’t replace the Phillips screws until the side
cover is properly positioned.)
If the hole is obstructed, remove the side cover and try again. It may take a
few tries.
Place the cover back on the printer
and press firmly until it snaps into place.
