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.

1. Remove the 7 strips of tape [A] as shown.

2. Open the front door and remove 4 strips of tape [B] as shown.

3. Pull out the paper tray [C], and remove a strip of tape [D] and the foam block [E] (1 tray for the duplex machine and 2 trays for the non-duplex machine).
