4. Appropriate power source. Make sure you use a grounded outlet; do not use an adapter plug. Avoid
electrical outlets controlled by timers or wall switches; an interruption in power can wipe out the
information in your computer or printer memory.
If you place the printer on a stand, follow these guidelines:
1. Use a stand that supports at least 9 kg (19 lb).
2. Never use a stand that tilts the printer. Always keep it level.
3. Provide enough clearance below the stand and between the printer rack and the legs of the rack so
the tractor paper flows smoothly.
4. Place cables to avoid interfere with paper feeding; secure them to a leg of the stand if possible.
