RELEASE ARM - The material of the Release Arm has been changed from
aluminum to iron to prevent it from becoming deformed. This will prevent the poor
image transfer associated with a bent Release Arm.
DESCRIPTION
Relase Arm
LEFT SCALE - With use, the Left Scale may warp slightly. This may allow
originals to go between the Left Scale and the Exposure Glass when they are
switched back. As a countermeasure, the material of the Left Scale has been
changed from ABS to Polycarbonate and the grooves on the back side have
been removed.
