Setting the drum drive disk, image shifting arm, pressure cylinder drive disk, and
scissors gear in their home positions
1. To set the drum drive disk in the home position, align the elongated hole [A] in
the drum drive disk straight down by turning the disk.
2. Set the image shift arm [B] in the home position. To do this, align the hole in the
upper plate [C] with the elongated hole in the image shift arm.
3. Align the hole in the pressure cylinder drive disk [D] with the hole in the side
plate of the drive unit [E], then install the bushing [F] (one E-ring).
NOTE: Before installing the bushing [F], make sure that the scissors gear [G]
also meshes with the next gear. If the scissors gear is set incorrectly by
180 degrees, the scissors gear will not mesh with that gear. (See OK
and NG in the diagram above.)
