❏ Avoid electrical outlets controlled by wall switches or automatic timers. An interruption in power
can erase information in the memory of your printer or computer. Also avoid outlets on the same
circuit as large motors or other appliances that can cause voltage fluctuations.
❏ Use a grounded power outlet; do not use an adapter plug.
❏ If you plan to use a printer stand, follow these guidelines:
- Use a stand that can support at least twice the weight of the printer.
- Never use a stand that tilts the printer. The printer should always be kept level.
- Position your printer’s power cord and interface cable so they do not interfere with paper
feeding. If possible, secure the cables to a leg of the printer stand.
❏ Do not place near the CRT display which emits strong electromagnetic wave.
When maintaining the printer
❏ Unplug the printer before cleaning it, and always clean it with a piece of damp cloth only.
❏ Do not spill liquid onto the printer.
❏ Do not attempt to service the printer yourself except as specifically explained in this guide.
❏ Unplug the printer and refer servicing to qualified service personnel under the following
conditions:
i. If the power cord or plug is damaged.
ii. If liquid has entered the printer.
iii. If the printer has been dropped or the cabinet damaged.
