General Safety Precautions - Printronix L5000 Series Maintenance Manual

General Safety Precautions

This chapter provides safety information for technicians who are installing and
maintaining L5000 Series printers. Installation, initial setup, testing and
maintenance should be performed only by a factory-trained service representative.
The printer relies on protective devices in the building installation for protection.
The printer must be connected to a 30 Amp, 250 V outlet. The operator-accessible
power switch does not shut off all power to the printer. You must unplug the power
cord to shut off all power to the printer.
When handling the printer, observe the following precautions to avoid accidents and
ensure safe operation:
Follow all safety notices and instructions printed in this manual and indicated on
the printer.
Remove packaging materials carefully, and save them for possible future use. If
the printer is powered on without removing all internal tape and packing, the
printer may be damaged.
Keep combustible materials away from the printer. Dispose of used toner
properly, as it is flammable.
Be aware of components in the printer that are potentially hazardous or easily
damaged. For example, the fuser unit becomes very hot under normal operating
conditions, and several components use high voltage.
If it is necessary to remove the fuser section after operating the printer, take care
not to touch its metal portions or cover glass.
Do not touch the following parts, as high voltages are present:
Do not touch the photoreceptor drum surface, due to the hazardous nature of the
material; it is also easily damaged.
Do not touch the developer roller assembly.
Do not touch the xenon and halogen lamps or fuser cover glass, as fingerprints on
lamps will absorb heat and cause them to break.
Do not place magnetically sensitive items near the developer roller assembly, as
it is magnetized.
Do not place the toner near vinyl material, as the toner melts vinyl chloride.
