phases(engagement between gears). Therefore, since procedures for
disassembly and assembly is quite difficult, this section has disassembly
procedure and assembly procedure separately. Refer to section 4.3.1 for

are assembled without matching each phases,
printer goes to fatal error with abnormal sound,
when the printer is turned on.
