1. This procedure is performed in the following case.
(1) When the lens unit is removed.
(2) When No. 4/5 mirror drive unit is disassembled.
(3) When the copy is out of focus because relative position of the lens
unit and No. 4/5 mirror unit is shifted by moving the lens unit itself
back and forth without turning the L drive pulley.
* In order to move the lens unit of this machine back and forth in
servicing, be sure to turn the L drive pulley. (If the lens unit itself is
moved, the wire may slip at the L drive pulley and the relative
position of the lens unit and No. 4/5 mirror unit is shifted, resulting
in improper focusing.)
