Troubleshooting

WARNINGS !

!Hazardous voltages are present in the 4100 printer. With the enclosure removed and power applied, hazardous voltage areas are present. Equipment service must be performed only by service-trained personnel who are aware of the hazards involved.

!Double-Pole/Neutral Fusing. The 4100 printer contains two fuses in the power receptable. It is possible for only one fuse to blow. If this occurs, be warned that, even though the POWER indicator is not lit, some printer electrical circuit may remain active. ALWAYS turn off the printer and unplug the power cord before checking the cause of the blown fuse(s) and before replacing the fuse(s).

!Use only the fuses specified. Never use repaired fuses, and never short- circuit a fuse holder.
