General Guidelines
For qualified service personnel only:
Refer also to the preceding Power Safety
Precautions.
Avoid servicing alone:
Do not perform internal service or adjustment of this product
unless another person capable of rendering first aid or resuscitation is present.
Use care when servicing with power:
Dangerous voltages may exist at several
points in this product. To avoid personal injury, do not touch exposed connections and
components while power is on. Disconnect power before removing the power supply
shield or replacing components.
Do not wear jewelry:
Remove jewelry prior to servicing. Rings, necklaces and other
metallic objects could come into contact with dangerous voltages and currents.
Power source:
This product is intended to operate from a power source that will not
apply more then 264 volts rms for a 220 volt AC outlet or 140 volts rms for a 110 volt
AC outlet between the supply conductors or between either supply conductor and
ground. A protective ground connection by way of the grounding conductor in the
power cord is essential for safe operation.
Warning Labels
Read and obey all posted warning labels. Throughout the printer, warning labels are
displayed on potentially dangerous components. As you service the printer, check to
make certain that all warning labels remain in place.
Safety Interlocks
Make sure covers and panel are in place and that all interlock switches are functioning
correctly after you have completed a printer service call. If you bypass an interlock
switch during a service call, use extreme caution when working on or around the
printer.
