NOTE: Keep the shipping retainers after installing the machine.
They will be reused if in the future the machine is
transported to another location.
Proper reinstallation of the shipping retainers is required in
order to avoid any transport damage. It is important to
replace the scanner lock pins and the scanner lock plate
before transporting this copier. If it is not done, skewed
image may result.
