Operational Guidelines
■ Do not block or cover the slots and openings on the printer. The printer may overheat 
without adequate ventilation.
■ For optimum performance, use the printer at elevations below 2,000 m (6,562 ft.).
■ Do not place the printer near a heat source.
■ Do not place the printer in direct sunlight to avoid exposure of light-sensitive components 
when the doors are open.
■ Do not place the printer in line with the cold air flow from an air conditioning system.
■ Place the printer on a level, solid non-vibrating surface with adequate strength for the 
weight of the printer. It should be within 2° of horizontal with all four feet in solid contact 
with the surface. The base printer weight without any packaging materials is 
approximately 89 kg (196 lb.).
Printing Safety Guidelines
■ Wait 10-15 seconds between turning the printer off and on.
■ Keep hands, hair, neckties, etc., away from the exit and feed rollers.
When the printer is printing:
■ Do not remove the paper source tray that you selected in either the printer driver or control 
panel.
■ Do not open the doors.
■ Do not move the printer.
Printer Supplies
■ Use the supplies specifically designed for your printer. The use of unsuitable materials 
may cause poor performance and a possible safety hazard.
■ Follow all warnings and instructions marked on, or supplied with, the printer, options, and 
supplies.
