Reassembling Notes
• When installing the motor bracket, fit the two holes "a" over the positioning bosses pro-
vided on the drive unit.
• Make sure that the locking arm clamps the motor.
• When installing the drive unit to the scanner frame ASSY, hold the resin part of the drive
unit, taking care not to grip the solenoid spring. Fully turn the cutter flange clockwise and
turn the upper blade to the angle shown below, and then fit the boss of the cutter flange
into the hole of the upper blade.
