Observe the following precautions when performing disassembly and assembly work. Be sure to unplug the power cord before working on the machine. Perform all reassembly work by reversing the order in which the component was disassembled, unless otherwise specified. Do not lose small parts (screws, etc. ) or insert them in the wrong place. Install all parts completely before operating the machine. Do not loosen the screws indicated as disallowed for removal. 3 DIS. /ASSEMBLY PI-108 PAPER FEED SECTION [1] Replacing a Paper-Feed Roller and Feed Roller Caution: Be sure the power cord has been unplugged from the wall outlet.
