Transporting Your Printer:

   Moving the Printer to a Nearby Location:

   As long as you keep the printer level, you can move it as it is to a 
   nearby location--within the same room or to a nearby room. If the 
   printer is tilted, toner might leak from the developer unit.

Shipping the Printer:

   Properly packing the printer requires all the original packing 
   materials.  You also need two large plastic bags to wrap the drum unit 
   and developer unit to prevent toner from spilling out during transit.

   Pack the printer and its accessories all the original carton. If you no
   longer have the original carton, individually pack each component in an
   appropriate box. Use adequate packing material to protect all 
   accessories and the printer body from damage.

   1. Turn off the power and unplug and disconnect the power cord.
   2. Remove the multipaper cassette. Remove the optional items such as the
      2nd-bin feeder or font cartridge, and pack them using the original
      packing materials.
   3. Remove the multipaper cassette. Remove the optional items such as the
      2nd-bin feeder or font cartridge, and pack them using the original
      packing materials.
   4. Remove the developer block, cleaning pad, and drum counter from the
      printer.
   5. Wrap the drum unit in the original black wrapper or a black cloth to
      prevent it from being exposed to light. Then put the drum unit in a
      plastic bag and seal the bag.

WARNING: Do not touch the drum surface.

   6. Put the developer unit in a plastic bag and seal the bag. This 
      prevents toner from leaking out of the developer unit and staining 
      the printer.
   7. Attach the original packing materials to the printer.
   8. Pack the printer body and parts in the packing carton.
